Automated Demand Response Opportunities in Wastewater Treatment Facilities  

SciTech Connect (OSTI)

Wastewater treatment is an energy intensive process which, together with water treatment, comprises about three percent of U.S. annual energy use. Yet, since wastewater treatment facilities are often peripheral to major electricity-using industries, they are frequently an overlooked area for automated demand response opportunities. Demand response is a set of actions taken to reduce electric loads when contingencies, such as emergencies or congestion, occur that threaten supply-demand balance, and/or market conditions occur that raise electric supply costs. Demand response programs are designed to improve the reliability of the electric grid and to lower the use of electricity during peak times to reduce the total system costs. Open automated demand response is a set of continuous, open communication signals and systems provided over the Internet to allow facilities to automate their demand response activities without the need for manual actions. Automated demand response strategies can be implemented as an enhanced use of upgraded equipment and facility control strategies installed as energy efficiency measures. Conversely, installation of controls to support automated demand response may result in improved energy efficiency through real-time access to operational data. This paper argues that the implementation of energy efficiency opportunities in wastewater treatment facilities creates a base for achieving successful demand reductions. This paper characterizes energy use and the state of demand response readiness in wastewater treatment facilities and outlines automated demand response opportunities.

Environmental Assessment for the High Explosives Wastewater Treatment Facility, Los Alamos National Laboratory, Los Alamos, New Mexico  

SciTech Connect (OSTI)

The Department of Energy (DOE) has identified a need to improve the management of wastewater resulting from high explosives (HE) research and development work at Los Alamos National Laboratory (LANL). LANL`s current methods off managing HE-contaminated wastewater cannot ensure that discharged HE wastewater would consistently meet the Environmental Protection Agency`s (EPA`s) standards for wastewater discharge. The DOE needs to enhance He wastewater management to e able to meet both present and future regulatory standards for wastewater discharge. The DOE also proposes to incorporate major pollution prevention and waste reduction features into LANL`s existing HE production facilities. Currently, wastewater from HE processing buildings at four Technical Areas (TAs) accumulates in sumps where particulate HE settles out and barium is precipitated. Wastewater is then released from the sumps to the environment at 15 permitted outfalls without treatment. The released water may contain suspended and dissolved contaminants, such as HE and solvents. This Environmental Assessment (EA) analyzes two alternatives, the Proposed Action and the Alternative Action, that would meet the purpose and need for agency action. Both alternatives would treat all HE process wastewater using sand filters to remove HE particulates and activated carbon to adsorb organic solvents and dissolved HE. Under either alternative, LANL would burn solvents and flash dried HE particulates and spent carbon following well-established procedures. Burning would produce secondary waste that would be stored, treated, and disposed of at TA-54, Area J. This report contains the Environmental Assessment, as well as the Finding of No Significant Impact and Floodplain Statement of Findings for the High Explosives Wastewater Treatment Facility.

Bingen wastewater treatment facility energy evaluation. A reconnaissance level technical assistance study for the city of Bingen  

SciTech Connect (OSTI)

In the fall of 1983, the city of Bingen was selected as a target community for the Local Government Technical Assistance (LGTA) Program. They requested the LGTA team to assist them in identifying cost-effective energy conservation opportunities at their wastewater treatment facility. A description of the wastewater treatment process, monthly energy cost and consumption data, and process in-flow data were collected and analyzed by the LGTA team. An onsite treatment facility evaluation was performed in March of 1984. The purpose of this report is to present the results of the LGTA energy inventory and to recommend directions for further study. The city of Bingen operates a small treatment plant which averages 9.6 million gallons per month (an average of 0.31 million gallons per day). The treatment process consists of passing wastewater through a comminutor, grit chamber, aeration basin, clarifier, and a chlorination contact chamber prior to releasing the treated water into the Columbia River. The solids portion of the waste stream is biologically treated by aerobic digesters before the sludge is trucked to a land disposal site. Annual electrical consumption at the facility averages about 80,000 kWh. As estimated by the LGTA equipment inventory, the largest electrical consuming process component is the operation of the brush aerators (approx.65% of the total process electrical consumption). An Energy Utilization Index (EUI) was determined on a bimonthly basis. Over the last 18 months, the EUI has averaged a very respectable 2.67 million Btus per million gallons of processed wastewater.

Biological treatment of a seafood processing wastewater  

SciTech Connect (OSTI)

The seafood industry in Tampa is a multi-million dollar-per-year industry which heavily impacts the environment with large volumes of wastewater containing high concentrations of suspended solids and nitrogen. A 10 liter per day, bench-scale, wastewater treatment facility was designed, constructed, and operated for approximately eight (8) months to collect treat ability data on a seafood-processing wastewater. The bench-scale reactor consisted of a single-sludge, extended aeration, modified Ludzack-Ettinger (MLE) process for biologically removing carbon, nitrogen, and phosphorus from the wastewater. Influent and effluent data collected on the system included: chemical oxygen demand (COD), total suspended solids (TSS), total Kjeldahl nitrogen (TKN), ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, total nitrogen (TN), pH, total phosphorus (TP), dissolved oxygen (DO), alkalinity, and temperature. All analyses were performed in accordance with Standard Methods (1992). Typical influent characteristics were: 900--4,000 mg/L COD, 45--110 mg/L TKN, 150--2,000 mg/L TSS, and 40--80 mg/L TP. Solids residence time (SRT) served as the primary control parameter with average STR's of 4.5, 6.4, 8.5, and 30.9 days observed during the study. The following biokinetic constants were determined from the data: a yield coefficient (Y) of 0.49 mg TSS/mg COD and an endogenous decay coefficient (k{sub e}) of 0.11 days{sup {minus}1}.

Wastewater treatment using ferrous sulfate  

SciTech Connect (OSTI)

Treatment of industrial wastewater with coagulants is used extensively in the thorough removal of emulsified tars and oils. The central plant laboratory at the Zhdanov Coke Works conducted investigations of the treatment of wastewater, subsequently used for quenching coke, with ferrous sulfate. Laboratory tests and subsequent industrial tests demonstrated the efficiency of the method. In order to further intensify the wastewater treatment process we conducted laboratory tests with the addition of certain quantities of other coagulation reagents, for example polyacrylamide (PAA) and caustic soda, in addition to the ferrous sulfate. The combined use of polyacrylamide and ferrous sulfate permits instant coagulation of the sludge and very rapid (5 to 10 min) clarification of the water. In addition, in this case the degree of purification of the water is less dependent on the initial concentration of impurities. The purification is also improved when caustic soda is added, raising the pH. From the data it is apparent that an identical degree of purification of the water may be achieved either by increasing the consumption of ferrous sulfate, or by adding PAA or NaOH. During industrial tests of the purification of wastewater with ferrous sulfate, we also investigated the resulting sludge. The use of ferrous sulfate causes a significant increase in its quantity (by a factor of 1.5 to 1.8) and in its oil content (by a factor of 2 to 2.5). The water content in the sludge decreases. The sludge (in the quantity of 0.6% of the charge) may be added to the coking charge.

Ceramic membrane treatment of petrochemical wastewater  

SciTech Connect (OSTI)

Ceramic alumina microfiltration membranes were evaluated for treatment of 3 aqueous streams containing heavy metals, oils, and solids at petrochemical manufacturing facilities. To the best of the author's knowledge, this is the first reported use of ceramic alumina membranes for process water and wastewater treatment in a US petrochemical plant. In a pilot test at a vinyl chloride monomer (VCM) plant, precipitated heavy metal solids were filtered with the membranes. On another stream at that site, the ceramic membrane pilot system successfully treated emulsions of 1,2-dichloroethane (EDC), water, and solids. Membrane filtration of a linear alkyl benzene (LAB) oily wastewater stream produced water with less than 5 ppmw oil and grease, after pretreatment with HCl and ferric chloride. A preliminary financial analysis shows that the installed system cost for a ceramic membrane unit is comparable to other membrane technologies, while operating costs are anticipated to be lower. Specific process conditions that are particularly amenable to treatment by ceramic membrane microfiltration are also given in the paper. 10 refs., 11 figs., 7 tabs.

Technical analysis of advanced wastewater-treatment systems for coal-gasification plants  

SciTech Connect (OSTI)

This analysis of advanced wastewater treatment systems for coal gasification plants highlights the three coal gasification demonstration plants proposed by the US Department of Energy: The Memphis Light, Gas and Water Division Industrial Fuel Gas Demonstration Plant, the Illinois Coal Gasification Group Pipeline Gas Demonstration Plant, and the CONOCO Pipeline Gas Demonstration Plant. Technical risks exist for coal gasification wastewater treatment systems, in general, and for the three DOE demonstration plants (as designed), in particular, because of key data gaps. The quantities and compositions of coal gasification wastewaters are not well known; the treatability of coal gasification wastewaters by various technologies has not been adequately studied; the dynamic interactions of sequential wastewater treatment processes and upstream wastewater sources has not been tested at demonstration scale. This report identifies key data gaps and recommends that demonstration-size and commercial-size plants be used for coal gasification wastewater treatment data base development. While certain advanced treatment technologies can benefit from additional bench-scale studies, bench-scale and pilot plant scale operations are not representative of commercial-size facility operation. It is recommended that coal gasification demonstration plants, and other commercial-size facilities that generate similar wastewaters, be used to test advanced wastewater treatment technologies during operation by using sidestreams or collected wastewater samples in addition to the plant's own primary treatment system. Advanced wastewater treatment processes are needed to degrade refractory organics and to concentrate and remove dissolved solids to allow for wastewater reuse. Further study of reverse osmosis, evaporation, electrodialysis, ozonation, activated carbon, and ultrafiltration should take place at bench-scale.

Designing a wastewater and storm water management system for a new sealed lead acid battery facility  

SciTech Connect (OSTI)

Design of a new lead acid battery manufacturing facility requires careful planning to ensure compliance with wastewater, storm water, air quality and hazardous waste regulations. A case history is presented describing the planning approach to development of a wastewater and storm water management system for an SLA (sealed lead acid) battery plant in Columbus, Georgia. Several pollution prevention concepts were utilized in the design of the wastewater management system, which resulted in an 80% reduction in wastewater volume, and at the same time ensured compliance with the mass-based federal categorical effluent limits. Storm water management features were focused on eliminating any outdoor areas of industrial activity by avoiding outdoor storage areas to the extent possible, containment of remaining areas, and stringent air emission control concepts. Federal effluent guidelines for the battery manufacturing point source category as well as federal regulations governing the industrial storm water discharge permitting program were the key factors in motivating the design concepts utilized. Areas affected by the design concepts included facility layout, HVAC system design, process recovery systems, chemical storage and containment, and wastewater treatment technology. The facility has been in compliance with all applicable environmental regulations since startup in August, 1992 and has been awarded the 1995 Matsushita Electric Corporation`s President`s Award for Environmental Excellence.

Energy efficiency in municipal wastewater treatment plants: Technology assessment  

SciTech Connect (OSTI)

The New York State Energy Research and Development Authority (NYSERDA) estimates that municipal wastewater treatment plants (WWTPs) in New York State consume about 1.5 billion kWh of electricity each year for sewage treatment and sludge management based on the predominant types of treatment plants, the results of an energy use survey, and recent trends in the amounts of electricity WWTPs use nationwide. Electric utilities in New York State have encouraged demand-side management (DSM) to help control or lower energy costs and make energy available for new customers without constructing additional facilities. This report describes DSM opportunities for WWTPs in New York State; discusses the costs and benefits of several DSM measures; projects energy impact statewide of the DSM technologies; identifies the barrier to implementing DSM at WWTPs; and outlines one possible incentive that could stimulate widespread adoption of DSM by WWTP operators. The DSM technologies discussed are outfall hydropower, on-site generation, aeration efficiency, time-of-day electricity pricing, and storing wastewater.

The key elements of the report are summarized as follows: Discharge of tritiated water is regulated worldwide. Differences exist in discharge limits and in regulatory philosophy from country to country and from state to state in the United States. Tritium from manmade sources is emitted into the atmosphere and discharged into the ground or directly to the oceans and to waterways that empty into the oceans. In 1989, reported worldwide emissions of tritium from nuclear power generating plants totaled almost 1,000,000 Curies (Ci).

Domestic wastewater treatment with membrane filtrationtwo years experience  

Science Journals Connector (OSTI)

This study tested domestic wastewater treatment membrane filtration without external cleaning in sustained long term operation. Domestic wastewater treatment plant monitoring was performed at the municipal wastewater treatment plant Devnska Nov Ves, Bratislava between February 2005 and July 2007. Two membrane modules were tested by immersion in the domestic wastewater treatment plant. The flat sheet membrane module was operated without external cleaning at a flux of 2060 L/m2 h for 6 months. The hollow fiber membrane module was operated for 4 months without external cleaning with a flux of 2045 L/m2 h. Parallel operation of flat sheet and hollow fiber membrane modules showed similar results in effluent water quality. Both membrane modules were able to effectively remove organic matter (as much as 91%) and more than 97% of NH4+?N. Nitrogen removal via denitrification was observed during the short periods with low oxygen concentration. Treated water contained suspended solids under measurable limits.

Mercury mass balance at a wastewater treatment plant employing sludge incineration with offgas mercury control  

Science Journals Connector (OSTI)

Efforts to reduce the deliberate use of mercury (Hg) in modern industrialized societies have been largely successful, but the minimization and control of Hg in waste streams are of continuing importance. Municipal wastewater treatment plants are collection points for domestic, commercial, and industrial wastewaters, and Hg removal during wastewater treatment is essential for protecting receiving waters. Subsequent control of the Hg removed is also necessary to preclude environmental impacts. We present here a mass balance for Hg at a large metropolitan wastewater treatment plant that has recently been upgraded to provide for greater control of the Hg entering the plant. The upgrade included a new fluidized bed sludge incineration facility equipped with activated carbon addition and baghouse carbon capture for the removal of Hg from the incinerator offgas. Our results show that Hg discharges to air and water from the plant represented less than 5% of the mass of Hg entering the plant, while the remaining Hg was captured in the ash/carbon residual stream exiting the new incineration process. Sub-optimum baghouse operation resulted in some of the Hg escaping collection there and accumulating with the ash/carbon particulate matter in the secondary treatment tanks. Overall, the treatment process is effective in removing Hg from wastewater and sequestering it in a controllable stream for secure disposal.

Protecting Lake Ontario - Treating Wastewater from the Remediated Low-Level Radioactive Waste Management Facility - 13227  

SciTech Connect (OSTI)

The Port Granby Project is part of the larger Port Hope Area Initiative, a community-based program for the development and implementation of a safe, local, long-term management solution for historic low level radioactive waste (LLRW) and marginally contaminated soils (MCS). The Port Granby Project involves the relocation and remediation of up to 0.45 million cubic metres of such waste from the current Port Granby Waste Management Facility located in the Municipality of Clarington, Ontario, adjacent to the shoreline of Lake Ontario. The waste material will be transferred to a new suitably engineered Long-Term Waste Management Facility (LTWMF) to be located inland approximately 700 m from the existing site. The development of the LTWMF will include construction and commissioning of a new Wastewater Treatment Plant (WWTP) designed to treat wastewater consisting of contaminated surface run off and leachate generated during the site remediation process at the Port Granby Waste Management Facility as well as long-term leachate generated at the new LTWMF. Numerous factors will influence the variable wastewater flow rates and influent loads to the new WWTP during remediation. The treatment processes will be comprised of equalization to minimize impacts from hydraulic peaks, fine screening, membrane bioreactor technology, and reverse osmosis. The residuals treatment will comprise of lime precipitation, thickening, dewatering, evaporation and drying. The distribution of the concentration of uranium and radium - 226 over the various process streams in the WWTP was estimated. This information was used to assess potential worker exposure to radioactivity in the various process areas. A mass balance approach was used to assess the distribution of uranium and radium - 226, by applying individual contaminant removal rates for each process element of the WTP, based on pilot scale results and experience-based assumptions. The mass balance calculations were repeated for various flow and load scenarios. (authors)

F/H Effluent Treatment Facility filtration upgrade alternative evaluations overview  

SciTech Connect (OSTI)

The F/H Effluent Treatment Facility (ETF) at the Savannah River Site (SRS) was designed to treat process wastewater from the 200-F/H Production Facilities (routine wastewater) as well as intermittent flows from the F/H Retention Basins and F/H Cooling Water Basins (nonroutine wastewater). Since start-up of the ETF at SRS in 1988, the treatment process has experienced difficulties processing routine and nonroutine wastewater. Studies have identified high bacteria and bacterial decomposition products in the wastewater as the cause for excessive fouling of the filtration system. In order to meet Waste Management requirements for the treatment of processed wastewater, an upgrade of the ETF filtration system is being developed. This upgrade must be able to process the nonroutine wastewater at design capacity. As a result, a study of alternative filter technologies was conducted utilizing simulated wastewater. The simulated wastewater tests have been completed. Three filter technologies, centrifugal polymeric ultrafilters, tubular polymeric ultrafilters, and backwashable cartridge filters have been selected for further evaluation utilizing actual ETF wastewater.

Innovative wastewater treatment using reversing anaerobic upflow system (RAUS)  

SciTech Connect (OSTI)

Anaerobic processes are widely popular in the treatment of a variety of industrial wastewaters since the development of such high rate treatment processes like upflow anaerobic sludge blanket (UASB), anaerobic filter, and the fluidized-bed process. In order to devise a low cost/high technology system so that it would provide an economical solution to environmentally sound pollution control, the Reversing Anaerobic Upflow System (RAUS) was developed. The system consists of two anaerobic reactors connected to each other. At the beginning, one reactor is fed upwards with wastewater while the other acts as a settling tank. After a set interval of time, the flow is reversed such that the second reactor is fed with wastewater and the first one acts as the settler. This particular feeding pattern had shown improved settling characteristics and granulation of methanogenic biomass from research carried out at the Hannover University with different wastewaters. The biological reaction vessels to which wastewater is introduced intermittently functions basically as a sludge blanket type reactor although the costly integrated settling devices present in a typical UASB system are avoided. The RAUS combines three principle reactor configurations: (1) conventional with sludge recycling; (2) fill and draw or sequential batch, inflow maintained constant during feeding; (3) upflow anaerobic sludge blanket. A pilot scale RAUS was operated for 400 days using distillery wastewater consisting of molasses slop and bottle washing water mixed in the ratio 1:1. This paper discusses the results of pilot scale experiments.

Groundwater Treatment at the Fernald Preserve: Status and Path Forward for the Water Treatment Facility - 12320  

SciTech Connect (OSTI)

Operating a water treatment facility at the Fernald Preserve in Cincinnati, Ohio-to support groundwater remediation and other wastewater treatment needs-has become increasingly unnecessary. The Fernald Preserve became a U.S. Department of Energy Office of Legacy Management (LM) site in November 2006, once most of the Comprehensive Environmental Response, Compensation, and Liability Act environmental remediation and site restoration had been completed. Groundwater remediation is anticipated to continue beyond 2020. A portion of the wastewater treatment facility that operated during the CERCLA cleanup continued to operate after the site was transferred to LM, to support the remaining groundwater remediation effort. The treatment facility handles the site's remaining water treatment needs (for groundwater, storm water, and wastewater) as necessary, to ensure that uranium discharge limits specified in the Operable Unit 5 Record of Decision are met. As anticipated, the need to treat groundwater to meet uranium discharge limits has greatly diminished over the last several years. Data indicate that the groundwater treatment facility is no longer needed to support the ongoing aquifer remediation effort. (authors)

Treatment of wool scouring wastewater for grease removal  

Science Journals Connector (OSTI)

Most of the wool scouring wastewater treatment systems in Australia consist of open anaerobic and facultative ponds which require large open areas. Apart from being unsightly and emitting odours, the plants are usually located in environmentally sensitive areas thereby causing environmental problems. There is a great need to look at alternative treatment systems which are more efficient and more environmentally acceptable. This study set out to investigate ways of reducing the grease content of the wastewater so that the pretreated wastewater can be fed to some high rate anaerobic digester. Various combinations of additions of coagulants, flocculants as well as using sulphuric acid for pH adjustment of the wastewater were attempted for assessing the extent of grease and COD removals. The study was also conducted at temperatures of 20 to 45C. It was found that up to 98% of grease and 79% of COD could be removed by just using sulphuric acid at a pH of between 2 and 3 and at a temperature of 20C. This work was first done on a batch basis. The work was extended into a continuous laboratory scale mixer-settler assembly which produced comparable results to those obtained batchwise.

Radiological Instrumentation Assessment for King County Wastewater Treatment Division  

SciTech Connect (OSTI)

The King County Wastewater Treatment Division (WTD) have concern about the aftermath of a radiological dispersion event (RDE) leading to the introduction of significant quantities of radioactive material into its combined sanitary and storm sewer system. Radioactive material could come from the use of a radiological dispersion device (RDD). RDDs include "dirty bombs" that are not nuclear detonations but are explosives designed to spread radioactive material. Radioactive material also could come from deliberate introduction or dispersion of radioactive material into the environment, including waterways and water supply systems. Volume 2 of PNNL-15163 assesses the radiological instrumentation needs for detection of radiological or nuclear terrorism, in support of decisions to treat contaminated wastewater or to bypass the West Point Treatment Plant (WPTP), and in support of radiation protection of the workforce, the public, and the infrastructure of the WPTP. Fixed radiation detection instrumentation should be deployed in a defense-in-depth system that provides 1) early warning of significant radioactive material on the way to the WPTP, including identification of the radionuclide(s) and estimates of the soluble concentrations, with a floating detector located in the wet well at the Interbay Pump Station and telemetered via the internet to all authorized locations; 2) monitoring at strategic locations within the plant, including 2a) the pipe beyond the hydraulic ram in the bar screen room; 2b) above the collection funnels in the fine grit facility; 2c) in the sampling tank in the raw sewage pump room; and 2d) downstream of the concentration facilities that produce 6% blended and concentrated biosolids. Engineering challenges exist for these applications. It is necessary to deploy both ultra-sensitive detectors to provide early warning and identification and detectors capable of functioning in high-dose rate environments that are likely under some scenarios, capable of functioning from 10 microrems per hour (background) up to 1000 rems per hour. Software supporting fixed spectroscopic detectors is needed to provide prompt, reliable, and simple interpretations of spectroscopic outputs that are of use to operators and decision-makers. Software to provide scientists and homeland security personnel with sufficient technical detail for identification, quantification, waste management decisions, and for the inevitable forensic and attribution needs must be developed. Computational modeling using MCNP software has demonstrated that useful detection capabilities can be deployed. In particular, any of the isotopes examined can be detected at levels between 0.01 and 0.1 ?Ci per gallon. General purpose instruments that can be used to determine the nature and extent of radioactive contamination and measure radiation levels for purposes of protecting personnel and members of the public should be available. One or more portable radioisotope identifiers (RIIDs) should be available to WTD personnel. Small, portable battery-powered personal radiation monitors should be widely available WTD personnel. The personal monitors can be used for personal and group radiation protection decisions, and to alert management to the need to get expert backup. All considerations of radiological instrumentation require considerations of training and periodic retraining of personnel, as well as periodic calibration and maintenance of instruments. Routine innocent alarms will occur due to medical radionuclides that are legally discharged into sanitary sewers on a daily basis.

Thermal sludge dryer demonstration: Bird Island Wastewater Treatment Plant, Buffalo, NY. Final report  

SciTech Connect (OSTI)

The Buffalo Sewer Authority (BSA), in cooperation with the New York State Energy Research and Development Authority (Energy Authority), commissioned a demonstration of a full scale indirect disk-type sludge dryer at the Bird Island Wastewater Treatment Plant (BIWWTP). The purpose of the project was to determine the effects of the sludge dryer on the sludge incineration process at the facility. Sludge incineration is traditionally the most expensive, energy-intensive unit process involving solids handling at wastewater treatment plants; costs for incineration at the BIWWTP have averaged $2.4 million per year. In the conventional method of processing solids, a series of volume reduction measures, which usually includes thickening, digestion, and mechanical dewatering, is employed prior to incineration. Usually, a high level of moisture is still present within sewage sludge following mechanical dewatering. The sludge dryer system thermally dewaters wastewater sludge to approximately 26%, (and as high as 38%) dry solids content prior to incineration. The thermal dewatering system at the BIWWTP has demonstrated that it meets its design requirements. It has the potential to provide significant energy and other cost savings by allowing the BSA to change from an operation employing two incinerators to a single incinerator mode. While the long-term reliability of the thermal dewatering system has yet to be established, this project has demonstrated that installation of such a system in an existing treatment plant can provide the owner with significant operating cost savings.

Radiological Risk Assessment for King County Wastewater Treatment Division  

SciTech Connect (OSTI)

Staff of the King County Wastewater Treatment Division (WTD) have concern about the aftermath of a radiological dispersion event (RDE) leading to the introduction of significant quantities of radioactive material into the combined sanitary and storm sewer system in King County, Washington. Radioactive material could come from the use of a radiological dispersion device (RDD). RDDs include "dirty bombs" that are not nuclear detonations but are explosives designed to spread radioactive material (National Council on Radiation Protection and Measurements (NCRP) 2001). Radioactive material also could come from deliberate introduction or dispersion of radioactive material into the environment, including waterways and water supply systems. This document develops plausible and/or likely scenarios, including the identification of likely radioactive materials and quantities of those radioactive materials to be involved. These include 60Co, 90Sr, 137Cs, 192Ir, 226Ra, plutonium, and 241Am. Two broad categories of scenarios are considered. The first category includes events that may be suspected from the outset, such as an explosion of a "dirty bomb" in downtown Seattle. The explosion would most likely be heard, but the type of explosion (e.g., sewer methane gas or RDD) may not be immediately known. Emergency first responders must be able to quickly detect the radioisotopes previously listed, assess the situation, and deploy a response to contain and mitigate (if possible) detrimental effects resulting from the incident. In such scenarios, advance notice of about an hour or two might be available before any contaminated wastewater reaches a treatment plant. The second category includes events that could go initially undetected by emergency personnel. Examples of such a scenario would be the inadvertent or surreptitious introduction of radioactive material into the sewer system. Intact rogue radioactive sources from industrial radiography devices, well-logging apparatus, or moisture density gages may get into wastewater and be carried to a treatment plant. Other scenarios might include a terrorist deliberately putting a dispersible radioactive material into wastewater. Alternatively, a botched terrorism preparation of an RDD may result in radioactive material entering wastewater without anyone's knowledge. Drinking water supplies may also be contaminated, with the result that some or most of the radioactivity ends up in wastewater.

Microbial ecology of denitrification in biological wastewater treatment  

Science Journals Connector (OSTI)

Abstract Globally, denitrification is commonly employed in biological nitrogen removal processes to enhance water quality. However, substantial knowledge gaps remain concerning the overall community structure, population dynamics and metabolism of different organic carbon sources. This systematic review provides a summary of current findings pertaining to the microbial ecology of denitrification in biological wastewater treatment processes. DNA fingerprinting-based analysis has revealed a high level of microbial diversity in denitrification reactors and highlighted the impacts of carbon sources in determining overall denitrifying community composition. Stable isotope probing, fluorescence in situ hybridization, microarrays and meta-omics further link community structure with function by identifying the functional populations and their gene regulatory patterns at the transcriptional and translational levels. This review stresses the need to integrate microbial ecology information into conventional denitrification design and operation at full-scale. Some emerging questions, from physiological mechanisms to practical solutions, for example, eliminating nitrous oxide emissions and supplementing more sustainable carbon sources than methanol, are also discussed. A combination of high-throughput approaches is next in line for thorough assessment of wastewater denitrifying community structure and function. Though denitrification is used as an example here, this synergy between microbial ecology and process engineering is applicable to other biological wastewater treatment processes.

Land treatment of contaminated sludge with wastewater irrigation  

SciTech Connect (OSTI)

A large-scale field experiment was conducted to test the feasibility of land application of sludge from industrial and domestic wastewater treatment to determine the fate and environmental impact of the contaminants. The sludge contained 13 organic priority pollutants, 16 additional environmentally significant organic compounds, and high concentrations of several metals (zinc, copper, lead, nickel, and cadmium). Each compound was monitored as the irrigation water percolated through the soil and the groundwater over time. Most of the organic compounds diminished to non-detectable levels by the end of the study, and the metals proved harmless to the environment. The effectiveness of land application of sludge with wastewater irrigation was clearly demonstrated. 1 figure, 11 tables.

Process waste treatment system upgrades: Clarifier startup at the nonradiological wastewater treatment plant  

SciTech Connect (OSTI)

The Waste Management Operations Division at Oak Ridge National Laboratory recently modified the design of a reactor/clarifier at the Nonradiological Wastewater Treatment Plant, which is now referred to as the Process Waste Treatment Complex--Building 3608, to replace the sludge-blanket softener/clarifier at the Process Waste Treatment Plant, now referred to as the Process Waste Treatment Complex-Building 3544 (PWTC-3544). This work was conducted because periodic hydraulic overloads caused poor water-softening performance in the PWTC-3544 softener, which was detrimental to the performance and operating costs of downstream ion-exchange operations. Over a 2-month time frame, the modified reactor/clarifier was tested with nonradiological wastewater and then with radioactive wastewater to optimize softening performance. Based on performance to date, the new system has operated more effectively than the former one, with reduced employee radiological exposure, less downtime, lower costs, and improved effluent quality.

Innovative Treatment Technologies for Natural Waters and Wastewaters  

SciTech Connect (OSTI)

The research described in this report focused on the development of novel membrane contactor processes (in particular, forward osmosis (FO), pressure retarded osmosis (PRO), and membrane distillation (MD)) in low energy desalination and wastewater treatment applications and in renewable energy generation. FO and MD are recently gaining national and international attention as viable, economic alternatives for removal of both established and emerging contaminants from natural and process waters; PRO is gaining worldwide attention as a viable source of renewable energy. The interrelationship of energy and water are at the core of this study. Energy and water are inextricably bound; energy usage and production must be considered when evaluating any water treatment process for practical application. Both FO and MD offer the potential for substantial energy and resource savings over conventional treatment processes and PRO offers the potential for renewable energy or energy offsets in desalination. Combination of these novel technologies with each other, with existing technologies (e.g., reverse osmosis (RO)), and with existing renewable energy sources (e.g., salinity gradient solar ponds) may enable much less expensive water production and also potable water production in remote or distributed locations. Two inter-related projects were carried out in this investigation. One focused on membrane bioreactors for wastewater treatment and PRO for renewable energy generation; the other focused on MD driven by a salinity gradient solar pond.

Operating experience with constructed wetlands for wastewater treatment  

SciTech Connect (OSTI)

Constructed wetlands are treating a variety of municipal, industrial, and runoff wastewaters. The growing interest in this technology is based on 20 years of research demonstrating the beneficial effects of wetlands on water quality, particularly their ability to assimilate carbonaceous and nitrogenous wastes. Constructed wetlands are an attractive option for applications where a land-intensive, natural' treatment technology is desired and where ancillary wildlife benefits will enhance a project's overall environmental balance sheet. This paper summarizes design and operating experience from constructed wetlands representing a variety of applications, including pilot systems in place at several US pulp mills.

Prediction of wastewater treatment plant performance using artificial neural networks  

Science Journals Connector (OSTI)

Artificial neural networks (ANN) models were developed to predict the performance of a wastewater treatment plant (WWTP) based on past information. The data used in this work were obtained from a major conventional treatment plant in the Greater Cairo district, Egypt, with an average flow rate of 1 million m3/day. Daily records of biochemical oxygen demand (BOD) and suspended solids (SS) concentrations through various stages of the treatment process over 10 months were obtained from the plant laboratory. Exploratory data analysis was used to detect relationships in the data and evaluate data dependence. Two ANN-based models for prediction of BOD and SS concentrations in plant effluent are presented. The appropriate architecture of the neural network models was determined through several steps of training and testing of the models. The ANN-based models were found to provide an efficient and a robust tool in predicting WWTP performance.

Environmental Assessment and Finding of No Significant Impact: Wastewater Treatment Capability Upgrade, Project NO. 96-D-122 Pantex Plant Amarillo, Texas  

SciTech Connect (OSTI)

This Environmental Assessment (EA) addresses the U.S. Department of Energy (DOE) proposed action regarding an upgrade of the Pantex Plant Wastewater Treatment Facility (WWTF). Potential environmental consequences associated with the proposed action and alternative actions are provided. DOE proposes to design, build, and operate a new WWTF, consistent with the requirements of Title 30 of the Texas Administrative Code (TAC), Chapter 317, ''Design Criteria for Sewage Systems,'' capable of supporting current and future wastewater treatment requirements of the Plant. Wastewater treatment at Pantex must provide sufficient operational flexibility to meet Pantex Plant's anticipated future needs, including potential Plant mission changes, alternative effluent uses, and wastewater discharge permit requirements. Treated wastewater effluent and non-regulated water maybe used for irrigation on DOE-owned agricultural land. Five factors support the need for DOE action: (1) The current WWTF operation has the potential for inconsistent permit compliance. (2) The existing WWTF lies completely within the 100-year floodplain. (3) The Pantex Plant mission has the potential to change, requiring infrastructure changes to the facility. (4) The life expectancy of the existing facility would be nearing its end by the time a new facility is constructed. (5) The treated wastewater effluent and non-regulated water would have a beneficial agricultural use through irrigation. Evaluation during the internal scoping led to the conclusion that the following factors are present and of concern at the proposed action site on Pantex Plant: (1) Periodic wastewater effluent permit exceedances; (2) Wetlands protection and floodplain management; (3) Capability of the existing facility to meet anticipated future needs of Pantex (4) Existing facility design life; and (5) Use of treated wastewater effluent and non-regulated water for irrigation. Evaluation during the internal scoping led to the conclusion that the following conditions are not present, nor of concern at the proposed site on Pantex Plant, and no further analysis was conducted: (1) State or national parks, forests, or other conservation areas; (2) Wild and scenic rivers; (3) Natural resources, such as timber, range, soils, minerals; (4) Properties of historic, archeological, or architectural significance; (5) Native American concerns; (6) Minority and low-income populations; and (7) Prime or unique farmland. In this document, DOE describes the proposed action and a reasonable range of alternatives to the proposed action, including the ''No-Action'' alternative. The proposed action cited in the ''U.S. Department of Energy Application for a Texas Pollutant Discharge Elimination System Permit Modifying Permit to Dispose of Waste, No. 02296,'' December 1998, included the construction of a new wastewater treatment facility, a new irrigation storage pond, and the conversion of the current wastewater treatment facility into an irrigation storage pond. Although a permit modification application has been filed, if a decision on this EA necessitates it, an amendment to the permit application would be made. The permit application would be required for any of the alternatives and the filing does not preclude or predetermine selection of an alternative considered by this EA. This permit change would allow Pantex to land-dispose treated wastewater by irrigating agricultural land. This construction for the proposed action would include designing two new lagoons for wastewater treatment. One of the lagoons could function as a facultative lagoon for treatment of wastewater. The second lagoon would serve as an irrigation storage impoundment (storage pond), with the alternative use as a facultative lagoon if the first lagoon is out of service for any reason. The new facultative lagoon and irrigation water storage pond would be sited outside of the 100-year flood plain. The existing WWTF lagoon would be used as a storage pond for treated wastewater effluent for irrigation water, as needed. The two new lagoons would be li

Hierarchical predictive control of integrated wastewater treatment systems  

Science Journals Connector (OSTI)

The paper proposes an approach to designing the control structure and algorithms for optimising control of integrated wastewater treatment plant-sewer systems (IWWTS) under a full range of disturbance inputs. The optimised control of IWWTS allows for significant cost savings, fulfilling the effluent discharge limits over a long period and maintaining the system in sustainable operation. Due to the specific features of a wastewater system a hierarchical control structure is applied. The functional decomposition leads to three control layers: supervisory, optimising and follow-up. A temporal decomposition that is applied in order to efficiently accommodate the system's multiple time scales leads to further decomposition of the optimising control layer into three control sublayers: slow, medium, and fast. An extended Kalman Filter is used to carry out an estimation of needed but not measured plant states in real time. The robustly feasible model predictive controller produces manipulated variable trajectories based on a dedicated grey box (GB) model of the biological processes and drawing its physical reality from the well known \\{ASM2d\\} model. The GB model parameters are dependant on the plant operating point and therefore are continuously estimated. As it is impossible to efficiently control the plant under all influent conditions that may occur by using one universal control strategy, different control strategies are designed. Recently developed mechanisms for soft switching between the MPC control strategies are applied in order to smooth the state and control transient processes during the switching. The methodologies and algorithms proposed in the paper are validated by simulation based on real data records from a wastewater system located in Kartuzy, northern Poland. The control system was implemented at the case-study site to generate in real time the control actions that were assessed by the plant operators and verified by simulation based on a calibrated plant model.

Photovoltaic Small-Scale Wastewater Treatment Project for Rural and New-Cultivated Areas in  

E-Print Network [OSTI]

AbstractThe problem of wastewater treatment in Egypt is a two-fold problem; the first part concerning the existing rural areas, the second one dealing with new industrial/domestic areas. In Egypt several agricultural projects have been initiated by the government and the private sector as well, in order to change its infrastructure. As a reliable energy source, photovoltaic pumping systems have contributed to supply water for local rural communities worldwide; they can also be implemented to solve the problem wastewater environment pollution. The solution of this problem can be categorised as recycle process. In addition, because of regional conditions past technologies are being reexamined to select a smallscale treatment system requiring low construction and maintenance costs. This paper gives the design guidelines of a Photovoltaic Small-Scale Wastewater Treatment Plant (PVSSWTP) based on technologies that can be transferred.

Fossil organic carbon in wastewater and its fate in treatment plants  

Science Journals Connector (OSTI)

Abstract This study reports the presence of fossil organic carbon in wastewater and its fate in wastewater treatment plants. The findings pinpoint the inaccuracy of current greenhouse gas accounting guidelines which defines all organic carbon in wastewater to be of biogenic origin. Stable and radiocarbon isotopes (13C and 14C) were measured throughout the process train in four municipal wastewater treatment plants equipped with secondary activatedsludge treatment. Isotopic mass balance analyses indicate that 414% of influent total organic carbon (TOC) is of fossil origin with concentrations between 6 and 35mg/L; 8898% of this is removed from the wastewater. The TOC mass balance analysis suggests that 3965% of the fossil organic carbon from the influent is incorporated into the activated sludge through adsorption or from cell assimilation while 2950% is likely transformed to carbon dioxide (CO2) during secondary treatment. The fossil organic carbon fraction in the sludge undergoes further biodegradation during anaerobic digestion with a 12% decrease in mass. 1.46.3% of the influent TOC consists of both biogenic and fossil carbon is estimated to be emitted as fossil CO2 from activated sludge treatment alone. The results suggest that current greenhouse gas accounting guidelines, which assume that all CO2 emission from wastewater is biogenic may lead to underestimation of emissions.

Combustion testing and heat recovery study: Frank E. Van Lare Wastewater Treatment Plant, Monroe County. Final report  

SciTech Connect (OSTI)

The objectives of the study were to record and analyze sludge management operations data and sludge incinerator combustion data; ascertain instrumentation and control needs; calculate heat balances for the incineration system; and determine the feasibility of different waste-heat recovery technologies for the Frank E. Van Lare (FEV) Wastewater Treatment Plant. As an integral part of this study, current and pending federal and state regulations were evaluated to establish their impact on furnace operation and subsequent heat recovery. Of significance is the effect of the recently promulgated Federal 40 CFR Part 503 regulations on the FEV facility. Part 503 regulations were signed into law in November 1992, and, with some exceptions, affected facilities must be in compliance by February 19, 1994. Those facilities requiring modifications or upgrades to their incineration or air pollution control equipment to meet Part 503 regulations must be in compliance by February 19, 1995.

A comprehensive substance flow analysis of a municipal wastewater and sludge treatment plant  

Science Journals Connector (OSTI)

Abstract The fate of total organic carbon, 32 elements (Al, Ag, As, Ba, Be, Br, Ca, Cd, Cl, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, N, Na, Ni, P, Pb, S, Sb, Se, Sn, Sr, Ti, V, and Zn) and 4 groups of organic pollutants (linear alkylbenzene sulfonates, bis(2-ethylhexyl)phthalate, polychlorinated biphenyl and polycyclic aromatic hydrocarbons) in a conventional wastewater treatment plant were assessed. Mass balances showed reasonable closures for most of the elements. However, gaseous emissions were accompanied by large uncertainties and show the limitation of mass balance based substance flow analysis. Based on the assessment, it is evident that both inorganic and organic elements accumulated in the sewage sludge, with the exception of elements that are highly soluble or degradable by wastewater and sludge treatment processes. The majority of metals and metalloids were further accumulated in the incineration ash, while the organic pollutants were effectively destroyed by both biological and thermal processes. Side streams from the sludge treatment process (dewatering and incineration) back to the wastewater treatment represented less than 1% of the total volume entering the wastewater treatment processes, but represented significant substance flows. In contrast, the contribution by spent water from the flue gas treatment process was almost negligible. Screening of human and eco-toxicity by applying the consensus-based environmental impact assessment method \\{USEtox\\} addressing 15 inorganic constituents showed that removal of inorganic constituents by the wastewater treatment plant reduced the toxic impact potential by 8792%.

STATUS REPORT: Onsite Wastewater Treatment Systems in California jointly presented by:  

E-Print Network [OSTI]

The regulation of onsite wastewater treatment systems will be undergoing significant changes in California in the coming years. Recent legislation has mandated that the State Water Resources Control Board develop and adopt statewide regulations by January 2004. These will be the first statewide regulations governing the use of onsite wastewater treatment in California. There are approximately 1.2 million onsite wastewater treatment systems in California, serving more than 3.5 million people, or 10 % of the states population. Since 1990, ten percent of new housing starts use onsite systems and this trend should continue for the foreseeable future. Onsite/decentralized systems are an integral part of the infrastructure used to support continued growth and development in the state. In April 1997, EPA published its Response to Congress on Use of Decentralized Wastewater Treatment Systems which concluded that, overall, adequately managed decentralized (onsite) wastewater treatment systems can be a cost effective and long-term option for meeting public health and water quality goals, particularly for small, suburban, and rural areas. Our dependence on onsite technologies has led to renewed interest in how they work. The performance of these systems is an important consideration in protecting the public health and water quality in the state. If onsite systems are recharging Californias

Science Journals Connector (OSTI)

Abstract The paper presents a wastewater treatment process and recycling of iron sludge from wastewater treatment for iron oxide red production. Results show that: (1) Sludge from wastewater treatment process under the operating parameters: 1.84g/L of NaOH dosage, 10mins of aeration with flow rate of 1L/min and 150mins of sediment time is potential for seed crystal preparation and excellent iron oxide red product can be obtained in the secondary oxidation under condition of 85C, 68h of reaction time and 150mL/min of airflow rate, (2) In practical engineering, the average removal rate of Fe2+ and SS and chroma of effluent is 99.75%, 86.7% and less than 40 times, respectively, and all items of product satisfy demands of industrial standards, (3) Compared with the original wastewater treatment, the new process can save the cost of wastewater treatment and earn extra 20.0 dollars for a ton of iron oxide red product and then both economic benefit and environmental protection can be realized by this process. It is proved that the novel method is reliable, economical and promising in iron oxide red industry and cleaner production of iron oxide red is feasible.

Tritiated wastewater treatment and disposal evaluation for 1995  

SciTech Connect (OSTI)

A second annual summary and analysis of potential processes for the mitigation of tritium contained in process effluent, ground water and stored waste is presented. It was prepared to satisfy the Hanford Federal Facility and Consent Order (Tri-Party Agreement) Milestone M-26-05B. Technologies with directed potential for separation of tritium at present environmental levels are organized into two groups. The first group consists of four processes that have or are undergoing significant development. Of these four, the only active project is the development of membrane separation technology at the Pacific Northwest Laboratory (PNL). Although research is progressing, membrane separation does not present a near term option for the mitigation of tritium. A second grouping of five early stage projects gives an indication of the breadth of interest in low level tritium separation. If further developed, two of these technologies might prove to be candidates for a separation process. At the present, there continues to be no known commercially available process for the practical reduction of the tritium burden in process effluent. Material from last year`s report regarding the occurrence, regulation and management of tritium is updated and included in the appendices of this report. The use of the State Approved Land Disposal Site (SALDS) for disposal of tritiated effluent from the 200 Area Effluent Treatment Facility (ETF) begins in the fall of 1995. This is the most significant event impacting tritium in the environment at the Hanford Site this coming year.

Zero liquid discharge industrial wastewater treatment: Case studies from 1976-1996  

SciTech Connect (OSTI)

As wastewater discharge regulations become more stringent, power plants, manufacturing plants and other industrial sites are looking for ways to reduce makeup water requirements and to recycle and reuse as much wastewater as possible. In some cases, environmental regulations require zero liquid discharge, meaning all wastewater must either be retained on site or reduced to solids for disposal off site. Zero liquid discharge or {open_quotes}closed-loop{close_quotes} wastewater treatment systems using evaporators and other process equipment have been well-accepted in recent years. Often overlooked is the fact that zero discharge is not just the latest fashion--many commercial zero liquid discharge systems have been in operation since the mid-70`s. This paper will give specific examples of zero liquid discharge operations from 1974 to the present, showing how evaporation equipment and processes have changed to meet the requirements of industry and environmental regulations. 5 refs., 5 figs., 3 tabs.

Feasibility study on production of biodegradable polymer and wastewater treatment using Aeromonas strains for materials recycling  

Science Journals Connector (OSTI)

Abstract With consideration of wastewater treatment and materials recycling for cradle-to-cradle (C2C) sustainable development, this treatability study analyzed the capability of poly 3-hydroxybutyrate (PHB) production in wastewater-laden media using indigenous dye-decolorizing Aeromonas hydrophila NIU01, KB23, Aeromonas salmonicida 741. Compared to paper-container, frozen food, wine manufacturing wastewater, wastewater generated from printing and dyeing industry was found to be more appropriate to efficiently produce PHB for materials recycling. Due to lack of sufficient essential inorganic nutrients provided for cell propagation, dye-decolorized wastewater with augmented MR media in different ratios was used to explore toxicity potency of mixed media and to present PHB-producing capability of cells. In particular, when MR media were completely replaced by decolorized culture broth, significant stimulating effect on PHA-production was shown (ca. 52.5% PHB content). This study clearly revealed the promising feasibility of simultaneous wastewater treatment and biopolymer production for cradle-to-cradle sustainable development.

Waste minimization necessary for solving wastewater problems  

SciTech Connect (OSTI)

Developing and implementing waste minimization procedures to correct the wastewater treatment problem are not as simple as identifying the problem. People cannot solve today's problems with the same kind of thinking that caused the problems. Nonetheless, industry primarily is using traditional treatment technologies to reduce wastewater. most companies are upgrading their wastewater treatment plants and installing treatment equipment in process areas whenever technically and economically feasible. The solution to ensuring wastewater compliance is recycling, waste minimization and moving toward zero discharge. Treating wastewater to the best possible quality still creates residual waste that must be disposed. In addition, regulatory limits continue to increase. Although some facilities can close and have closed the loop in certain processes, industry is pursuing waste minimization and the goal of zero discharge, given existing technology and economics. This, companies must taken an innovative approach to reducing wastewater volume and toxicity at the source.

Demonstration of membrane aeration panels: City of Geneva Wastewater Treatment Plant. Final report  

SciTech Connect (OSTI)

This report describes the design, construction, and testing of membrane aeration panels at the Marsh Creek wastewater treatment plant (WWTP) in Geneva, NY. The operators at the Geneva plant have undertaken a long-term program to upgrade wastewater treatment processes and lower operating costs. The aging mechanical surface aerators at the Marsh Creek treatment plant were replaced by a state-of-the-art membrane panel system. This fine-bubble diffused air system offers higher oxygen transfer efficiency than surface aerators or other types of fine-bubble diffused-air systems. The project had four objectives: to decrease the amount of electricity used at the plant for aeration; to enable the plant`s existing aeration basins to accommodate higher organic loads and/or nitrify the wastewater should the need arise; to provide an even distribution of dissolved oxygen within the aeration basins to enhance biological wastewater treatment activity; and to provide technical data to assess the performance of the membrane panel system versus other forms of wastewater aeration.

Structural redundancy of data from wastewater treatment systems. Determination of individual balance equations  

Science Journals Connector (OSTI)

Abstract Although data reconciliation is intensely applied in process engineering, almost none of its powerful methods are employed for validation of operational data from wastewater treatment plants. This is partly due to some prerequisites that are difficult to meet including steady state, known variances of process variables and absence of gross errors. However, an algorithm can be derived from the classical approaches to data reconciliation that allows to find a comprehensive set of equations describing redundancy in the data when measured and unmeasured variables (flows and concentrations) are defined. This is a precondition for methods of data validation based on individual mass balances such as CUSUM charts. The procedure can also be applied to verify the necessity of existing or additional measurements with respect to the improvement of the data's redundancy. Results are given for a large wastewater treatment plant. The introduction aims at establishing a link between methods known from data reconciliation in process engineering and their application in wastewater treatment.

Anaerobic treatment of high-sulfate wastewater and substrate interactions with isopropanol  

SciTech Connect (OSTI)

Modified biological methane-potential tests were used to study the treatment of wastewater with a chemical oxygen demand (COD) concentration of 40,000 mg/L and a sulfate concentration of 5,000 mg/L. The effects of wastewater concentrations on biodegradation and substrate interactions between sulfate reducers and methanogens were studied. Isopropanol (IPA) degradation was studied since isopropyl acetate was the major organic component in the wastewater. Six sets of batch tests were done, including a series of tests with varying concentrations of wastewater; wastewater and glucose; glucose and sulfate; IPA; IPA and glucose; and IPA, glucose, and sulfate. Sulfur and electron balances were used to analyze data to determine the extent of biodegradation from both methanogenesis and sulfate reduction. IPA did not appear to be inhibitory to methanogenesis or sulfate reduction. In comparison to glucose, the presence of wastewater or isopropanol stimulated greater sulfate-reduction efficiency. Evidence for IPA degradation was observed, and IPA degradation was stimulated in the presence of sulfate. Continuous feed-reactor results corroborated batch-test observations.

Optimization of diclofenac quantification from wastewater treatment plant sludge by ultrasonication assisted extraction  

Science Journals Connector (OSTI)

Abstract A rapid quantification method of diclofenac from sludge samples through ultrasonication assisted extraction and solid phase extraction (SPE) was developed and used for the quantification of diclofenac concentrations in sludge samples with liquid chromatography/tandem mass spectrometry (LCMS/MS). Although the concentration of diclofenac in sludge samples taken from different units of wastewater treatment plants in Istanbul was below the limit of quantification (LOQ; 5ng/g), an optimized method for sludge samples along with the total mass balances in a wastewater treatment plant can be used to determine the phase with which diclofenac is mostly associated. Hence, the results will provide information on fate and transport of diclofenac, as well as on the necessity of alternative removal processes. In addition, since the optimization procedure is provided in detail, it is possible for other researchers to use this procedure as a starting point for the determination of other emerging pollutants in wastewater sludge samples.

Impact of approach used to determine removal levels of drugs of abuse during wastewater treatment  

Science Journals Connector (OSTI)

Abstract In this study the levels of 19 drugs of abuse were estimated throughout a wastewater treatment plant using polar organic chemical integrative samplers (POCIS), 24h composite samples and grab samples. Overall removal efficiencies and removals in between each treatment unit were calculated using load data for each sampling technique as well as removals that take into account the hydraulic residence time distribution of the treatment plant (time-shifted mass balancing approach). Amphetamine-type stimulants, cocaine and its major metabolite, benzoylecgonine and opioid levels determined with 24h composite samples were generally comparable to those obtained with POCIS and grab samples. Negative mass balances resulting from the estimation of overall removal efficiencies by POCIS, day-to-day mass balancing of 24h composite and grab sample data did not occur when the hydraulic retention time (HRT) distributions of the plant were taken into account for calculation. Among the compounds investigated, cocaine exhibited the highest overall removal (90%) while codeine had the lowest with 13%, respectively. Sampling between the treatment units revealed that highest removal occurs during biological treatment as compared to primary or secondary clarification. Methylenedioxyamphetamine (MDA), fentanyl, dihydrocodeine and heroin were not detected in wastewater at any of the sampling locations at the treatment plant regardless of the sampling technique. The study demonstrates the benefits of applying the time-shifted mass balancing approach to the calculation of removals of drugs of abuse during wastewater treatment.

Occurrence of pharmaceuticals in a municipal wastewater treatment plant: Mass balance and removal processes  

Science Journals Connector (OSTI)

Occurrence and removal efficiencies of fifteen pharmaceuticals were investigated in a conventional municipal wastewater treatment plant in Michigan. Concentrations of these pharmaceuticals were determined in both wastewater and sludge phases by a high-performance liquid chromatograph coupled to a tandem mass spectrometer. Detailed mass balance analysis was conducted during the whole treatment process to evaluate the contributing processes for pharmaceutical removal. Among the pharmaceuticals studied, demeclocycline, sulfamerazine, erythromycin and tylosin were not detected in the wastewater treatment plant influent. Other target pharmaceuticals detected in wastewater were also found in the corresponding sludge phase. The removal efficiencies of chlortetracycline, tetracycline, sulfamerazine, acetaminophen and caffeine were >99%, while doxycycline, oxytetracycline, sulfadiazine and lincomycin exhibited relatively lower removal efficiencies (e.g., mass, i.e. 41% more than the input from the influent. Based on the mass balance analysis, biotransformation is believed to be the predominant process responsible for the removal of pharmaceuticals (22% to 99%), whereas contribution of sorption to sludge was relatively insignificant (7%) for the investigated pharmaceuticals.

Optimizing a Modular Expansion of a Wastewater Treatment Plant Using Option Theory and Moment Matching Approximation Abstract  

E-Print Network [OSTI]

We consider a municipality faced with the question of how big to make their new wastewater treatment facility to meet the demand of 10 % expected growth in the number of new connections. Previously, we developed a real options framework for determining optimal plant size and showed that the model takes on the form of an Asian option. Furthermore, it was shown that if the connection rate growths are closely correlated with the market growth, then the penalty costs associated with having insufficient capacity to treat the wastewater can be effectively hedged, significantly reducing overall expected costs. In this study, we introduce an approximate analytical solution and optimize the plant size of a staged / modular expansion. Based on the given construction cost estimates, we show that a staged expansion has a minimal (expected) savings when connection growth rates are closely correlated to the market growth rates. However, as the correlation decreases to zero, or, alternatively, no attempt is made to hedge the penalty costs, a staged expansion has an expected savings of 20%.

Analysis, anaerobic treatment and ozonation of wool scouring wastewater  

SciTech Connect (OSTI)

Wool scouring effluents (WSE) were analyzed by high-resolution gas chromatography-mass spectrometry (HRGC-MS), and then exposed to anaerobic biological treatment using laboratory scale fixed-bed filters. This resulted in a nearly 50% reduction in chemical oxygen demand (COD). Ozonation of the effluent from the biological step led to an even further decrease in total organic carbon (TOC). The fatty acid content of the WSE was affected by both biological treatment and ozonation. Finally, steroids in the WSE underwent reduction reactions when exposed to the anaerobic biological treatment.

Elimination of liquid discharge to the environment from the TA-50 Radioactive Liquid Waste Treatment Facility  

SciTech Connect (OSTI)

Alternatives were evaluated for management of treated radioactive liquid waste from the radioactive liquid waste treatment facility (RLWTF) at Los Alamos National Laboratory. The alternatives included continued discharge into Mortandad Canyon, diversion to the sanitary wastewater treatment facility and discharge of its effluent to Sandia Canyon or Canada del Buey, and zero liquid discharge. Implementation of a zero liquid discharge system is recommended in addition to two phases of upgrades currently under way. Three additional phases of upgrades to the present radioactive liquid waste system are proposed to accomplish zero liquid discharge. The first phase involves minimization of liquid waste generation, along with improved characterization and monitoring of the remaining liquid waste. The second phase removes dissolved salts from the reverse osmosis concentrate stream to yield a higher effluent quality. In the final phase, the high-quality effluent is reused for industrial purposes within the Laboratory or evaporated. Completion of these three phases will result in zero discharge of treated radioactive liquid wastewater from the RLWTF.

A mass balance method for assessing the potential of artificial wetlands for wastewater treatment  

Science Journals Connector (OSTI)

Artificial wetlands have been shown to have potential for treating wastewaters. An experimental artificial wetland is described together with a mass balance method for quantifying system performance, major nutrient storage components and nutrient removal mechanisms. The experimental systems were capable of a high level of performance. Percentage load removals for chemical oxygen demand, total nitrogen and total phosphorus were 86, 95 and 99%, respectively. Plant biomass was found to be the major nutrient storage compartment with plant nutrient uptake being the major removal mechanism. It was found that overall system performance could be described by a simple first order, steady state model. System design and hydrology were considered important factors in determining treatment performance. Designs must maximize wastewater-rootzone contact. The experimental systems used an upflow hydraulic format to achieve this design objective.

The behaviors and fate of polycyclic aromatic hydrocarbons (PAHs) in a coking wastewater treatment plant  

Science Journals Connector (OSTI)

The occurrence, behaviors and fate of 18 \\{PAHs\\} were investigated in a coking wastewater treatment plant in Songshan coking plant, located in Shaoguan, Guangdong Province of China. It was found that the target compounds occurred widely in raw coking wastewater, treated effluent, sludge and gas samples. In raw coking wastewater, high molecular weight (MW) \\{PAHs\\} were the dominant compounds, while 36 ring \\{PAHs\\} predominated in the final effluent. The dominant compounds in gas samples were phenathrene, fluoranthene and pyrene, while they were fluoranthene, pyrene, chrysene and benzo[k]fluoranthene for sludge. The process achieved over 97% removal for all the PAHs, 4792% of eliminations of these target compounds in liquid phase were achieved in biological stage. Different behaviors of \\{PAHs\\} were observed in the primary tank, anaerobic tank, aerobic tank, hydrolytic tank and coagulation tank units, while heavier and lower ones were mainly removed in anaerobic tank and aerobic tanks, respectively. Regarding the fate of PAHs, calculated fractions of mass losses for low MW \\{PAHs\\} due to transformation and adsorption to sludge accounted for 1550% and 2449%, respectively, while the rest was less than 1%. For high MW PAHs, the mass losses were mainly due to adsorption to sludge and separation with tar (contributing 5676% and 2239%, respectively), and the removal through transformation was less.

Environmental impact of recycling nutrients in human excreta to agriculture compared with enhanced wastewater treatment  

Science Journals Connector (OSTI)

Abstract Human excreta are potential sources of plant nutrients, but are today usually considered a waste to be disposed of. The requirements on wastewater treatment plants (WWTPs) to remove nitrogen and phosphorus are increasing and to meet these requirements, more energy and chemicals are needed by WWTPs. Separating the nutrient-rich wastewater fractions at source and recycling them to agriculture as fertiliser is an alternative to removing them at the WWTP. This study used life cycle assessment methodology to compare the environmental impact of different scenarios for recycling the nutrients in the human excreta as fertiliser to arable land or removing them in an advanced WWTP. Three scenarios were assessed. In blackwater scenario, blackwater was source-separated and used as fertiliser. In urine scenario, the urine fraction was source-separated and used as fertiliser and the faecal water treated in an advanced WWTP. In NP scenario, chemical fertiliser was used as fertiliser and the toilet water treated in an advanced WWTP. The emissions from the WWTP were the same for all scenarios. This was fulfilled by the enhanced reduction in the WWTP fully removing the nutrients from the excreta that were not source-separated in the NP and urine scenarios. Recycling source-separated wastewater fractions as fertilisers in agriculture proved efficient for conserving energy and decreasing global warming potential (GWP). However, the blackwater and urine scenarios had a higher impact on potential eutrophication and potential acidification than the WWTP-chemical fertiliser scenario, due to large impacts by the ammonia emitted from storage and after spreading of the fertilisers. The cadmium input to the arable soil was very small with urine fertiliser. Source separation and recycling of excreta fractions as fertiliser thus has potential for saving energy and decreasing GWP emissions associated with wastewater management. However, for improved sustainability, the emissions from storage and after spreading of these fertilisers must decrease.

Method and apparatus for energy efficient self-aeration in chemical, biochemical, and wastewater treatment processes  

DOE Patents [OSTI]

The present invention is a pulse spilling self-aerator (PSSA) that has the potential to greatly lower the installation, operation, and maintenance cost associated with aerating and mixing aqueous solutions. Currently, large quantities of low-pressure air are required in aeration systems to support many biochemical production processes and wastewater treatment plants. Oxygen is traditionally supplied and mixed by a compressor or blower and a mechanical agitator. These systems have high-energy requirements and high installation and maintenance costs. The PSSA provides a mixing and aeration capability that can increase operational efficiency and reduce overall cost.

Data evaluation of full-scale wastewater treatment plants by mass balance  

Science Journals Connector (OSTI)

Measured data of wastewater treatment plants (WWTPs) often contains errors. These errors can prohibit the use of WWTP data for process evaluation, process design, benchmarking or modelling purposes. In this paper a practical stepwise methodology is presented to check WWTP data using mass balances. The presented results show that poor WWTP data quality leads to large errors when calculating key operational conditions such as the solids retention time (SRT), oxygen consumption (OC) and the different internal conversions rates. By improving WWTP data quality using mass balance calculations useful new information becomes available for process evaluation, \\{WWTPs\\} design and benchmarking.

Greenhouse gas emission by wastewater treatment plants of the pulp and paper industry Modeling and simulation  

Science Journals Connector (OSTI)

Abstract Greenhouse gas (GHG) emission and energy consumption in wastewater treatment plants (WWTPs) of the pulp and paper industry were modeled and estimated. Aerobic, anaerobic, and hybrid biological processes were used for the removal of contaminants. In addition to the removal of carbonaceous compounds, anaerobic digestion of the produced sludge and the removal of excess nitrogen in the effluent of treatment plants by nitrification/denitrification processes were incorporated in the model. Carbon dioxide, methane, and nitrous oxide were the major \\{GHGs\\} generated during the biological treatment, combustion, energy generation, and transportation. The generated biogas from the anaerobic processes was assumed to be recovered and used as a source of energy for the treatment plant, in an effort to reduce GHG emissions while decreasing the total energy needs of the WWTP. The established kinetic relationships of wastewater treatment processes along with mass and energy balances were employed for the simulation of different treatment systems and estimation of GHG emissions. Various sources of GHG emission were divided into on-site and off-site sources to simplify the modeling and simulation procedure. The overall GHG generation in the presence of biogas recovery was equal to 1.576, 3.026, and 3.271kg CO2-equivalent/kg BOD by the three examined systems. The energy produced by the recovery and combustion of biogas could exceed the energy demands of all different treatment plants examined in this study and reduce off-site GHG emission. The generation of \\{GHGs\\} from aerobic and hybrid processes increased by 27% and 33.2%, respectively, when N2O emission from nitrogen removal processes was taken into consideration.

Occurrence and fate of polycyclic musks in wastewater treatment plants in Kentucky and Georgia, USA  

Science Journals Connector (OSTI)

Wastewater treatment plants (WWTPs) are a potential of source of polycyclic musks in the aquatic environment. In this study, contamination profiles and mass flow of polycyclic musks, 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[?]-2-benzopyran (HHCB), 7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene (AHTN), and HHCB-lactone (oxidation product of HHCB), in two WWTPs, one located in Kentucky (Plant A, rural area) and the other in Georgia (Plant B, urban), USA, were determined. HHCB, AHTN and HHCB-lactone were detected in the influent, effluent, and sludge samples analyzed. The concentrations in wastewater samples varied widely, from 10 to 7030ng/l, 13 to 5400ng/l, and 66 to 790ng/l, for HHCB, AHTN, and HHCB-lactone, respectively. Sludge samples contained HHCB at Plant A and 31g/day from Plant B. Mass balance analysis suggested that only 30% of HHCB and AHTN entering the plants was accounted for in the effluent and the sludge. Removal efficiencies of HHCB and AHTN in the two \\{WWTPs\\} ranged from 72% to 98%. In contrast, HHCB-lactone concentrations increased following the treatment. Concentrations of polycyclic musks in sludge were on the order of several parts per million. Incineration of sludge at one plant reduced the concentration of polycyclic musks.

K-1435 Wastewater Treatment System for the Toxic Substances Control Act Incinerator Wastewater at the East Tennessee Technology Park, Oak Ridge, TN  

SciTech Connect (OSTI)

This paper discusses the design and performance of a wastewater treatment system installed to support the operation of a hazardous waste incinerator. The Oak Ridge Toxic Substances Control Act Incinerator (TSCAI), located at the East Tennessee Technology Park (ETTP), is designed and permitted to treat Resource ConservatioN and Recovery Act (RCRA) wastes including characteristic and listed wastes and polychlorinated biphenyl (PCB)-contaminated mixed waste. the incinerator process generates acidic gases and particulates which consist of salts, metals, and radionuclides. These off-gases from the incinerator are treated with a wet off-gas scrubber system. The recirculated water is continuously purged (below down), resulting in a wastewater to be treated. Additional water sources are also collected on the site for treatment, including storm water that infiltrates into diked areas and fire water from the incinerator's suppression system. To meet regulatory requirements for discharge, a wastewater treatment system (WWTS) was designed, constructed, and operated to treat these water sources. The WWTS was designed to provide for periodic fluctuation of contaminant concentrations due to various feed streams to the incinverator. Blow down consists of total suspended solids (TSS) and total dissolved solids (TDS), encompassing metals, radionuclide contamination and trace organics. The system design flow rate range is 35 to 75 gallons per minute (gpm). The system is designed with redundancy to minimize time off-line and to reduce impacts to the TSCAI operations. A novel treatment system uses several unit operations, including chemical feed systems, two-stage chemical reaction treatment, microfiltration, sludge storage and dewatering, neutralization, granular activated carbon, effluent neutralization, and a complete programmable logic controller (PLC) and human-machine interface (HMI) control system. To meet the space requirements and to provide portability of the WWTS to other applications, the system was installed in three, over-the-road semi trailers, and interconnected with piping and power. Trailers were oriented on a small site footprint to facilitate ease of installation. A remote sump pump skid was provided to convey water from two holding sumps adjacent to the treatment process. An accumulation tank and pump were also provided to receive miscellaneous wastewaters for treatment if they meet the waste acceptance criteria. The paper includes details of the technology used in the design, the requirements for compliance, and the initial performance demonstration and jar testing results. The WWTS successfully allowed for highly efficient, high-volume treatment with compliant discharge to off-site surface water.

Treatment of concentrated industrial wastewaters originating from oil shale and the like by electrolysis polyurethane foam interaction  

DOE Patents [OSTI]

Highly concentrated and toxic petroleum-based and synthetic fuels wastewaters such as oil shale retort water are treated in a unit treatment process by electrolysis in a reactor containing oleophilic, ionized, open-celled polyurethane foams and subjected to mixing and laminar flow conditions at an average detention time of six hours. Both the polyurethane foams and the foam regenerate solution are re-used. The treatment is a cost-effective process for waste-waters which are not treatable, or are not cost-effectively treatable, by conventional process series.

Treatment of an agrochemical wastewater by integration of heterogeneous catalytic wet hydrogen peroxide oxidation and rotating biological contactors  

Science Journals Connector (OSTI)

Abstract The treatment of a non-biodegradable agrochemical wastewater has been studied by coupling of heterogeneous catalytic wet hydrogen peroxide oxidation (CWHPO) and rotating biological contactors (RBCs). The influence of the hydrogen peroxide dosage and the organic content of the wastewater (dilution degree) were studied. The CWHPO of the raw wastewater at 80C and using a moderate amount of oxidant (0.23gH2O2/gTOC) reduced significantly its total organic carbon content and increased its biodegradability. Likewise, the iron leaching of the heterogeneous catalyst (Fe2O3/SBA-15) was less than 2mg/L in the treated effluent. Under the best operating conditions, the resultant CWHPO effluent was successfully co-treated by rotating biological contactors (RBCs) using a simulated municipal wastewater with different percentages of the CWHPO effluent (2.5, 5 and 10%v/v). The \\{RBCs\\} showed high stability for the treatment of the highest percentage of the CWHPO effluent, achieving total organic carbon (TOC) and total nitrogen (TN) reductions of ca. 78% and 50%, respectively. The integration of both processes on a continuous mode has been successfully accomplished for the treatment of the as-received agrochemical wastewater.

Obtaining process mass balances of pharmaceuticals and triclosan to determine their fate during wastewater treatment  

Science Journals Connector (OSTI)

Abstract To better understand pharmaceutical fate during wastewater treatment, analysis in both aqueous and particulate phases is needed. Reported herein is a multi-residue method for the determination of ten pharmaceutical drugs and the personal care product triclosan in wastewater matrices. Method quantitation limits ranged from 7.6 to 76.6ngl?1 for aqueous phases and from 7.0 to 96.7ngg?1 for particulate phases. The analytical method was applied to attain a complete process mass balance of a pilot-scale activated sludge plant (ASP) operated under controlled conditions. The mass balance (inclusive of aqueous and particulate concentrations at all sample points) was used to diagnose removal, revealing pharmaceuticals to be separable into three fate pathways: (a) biological degradation, (b) sorption onto activated sludge and (c) resistant to removal from the aqueous phase. These differences in fate behaviour explained a broad range of secondary removal observed (?8 to 99%). The ASP was also simultaneously compared to a full-scale trickling filter (TF) works whilst receiving the same influent wastewater. Performance of the ASP and TF was similar, achieving total pharmaceutical removals of 253 and 249?gg?1 biochemical oxygen demand (BOD) removed, respectively. This corresponded with reductions in total pharmaceutical load of 91 and 90% (ANOVA, p-value>0.05). Interestingly, despite low suspended solid concentrations final effluents of both the ASP and TF contained significant concentrations of some chemicals in the particulate phase. Individually, triclosan and the antibiotics ofloxacin and ciprofloxacin were within the particulate phase of effluents at concentrations ranging from 26 to 296ngl?1.

Engineered nanoparticles in wastewater and wastewater sludge - Evidence and impacts  

SciTech Connect (OSTI)

Nanotechnology has widespread application in agricultural, environmental and industrial sectors ranging from fabrication of molecular assemblies to microbial array chips. Despite the booming application of nanotechnology, there have been serious implications which are coming into light in the recent years within different environmental compartments, namely air, water and soil and its likely impact on the human health. Health and environmental effects of common metals and materials are well-known, however, when the metals and materials take the form of nanoparticles - consequential hazards based on shape and size are yet to be explored. The nanoparticles released from different nanomaterials used in our household and industrial commodities find their way through waste disposal routes into the wastewater treatment facilities and end up in wastewater sludge. Further escape of these nanoparticles into the effluent will contaminate the aquatic and soil environment. Hence, an understanding of the presence, behavior and impact of these nanoparticles in wastewater and wastewater sludge is necessary and timely. Despite the lack of sufficient literature, the present review attempts to link various compartmentalization aspects of the nanoparticles, their physical properties and toxicity in wastewater and wastewater sludge through simile drawn from other environmental streams.

Abatement efficiency of municipal wastewater treatment plants using different technologies (Orbetello Lagoon, Italy)  

Science Journals Connector (OSTI)

Two small-scale municipal wastewater treatment plants (Neghelli and Terrarossa) discharging effluents into a lagoon of great environmental interest and highly stressed by tourism (Orbetello, Italy) were monitored over the year 2001. We evaluated plants' performances developing a general efficiency indicator of removal to select the suitable purification technology (activated sludge, Neghelli vs. rotating biodisc reactor, Terrarossa). Unexpected, conventional technologies (activated sludge) had best performances (84% vs. 62%) with higher removal efficiencies for dissolved nutrients producing, on average, better final effluents. Even if Terrarossa showed a great improvement in summertime, during winter it seemed to be considerably affected by sea aerosol. Before the final discharge in lagoon, effluents were phytodepurated in a pond to reduce their nutrient load. Although data showed that the pond had further abatement efficiency over 80%, final outlet water represented a dangerous input for the lagoon ecosystem.

An evaluation of tannery industry wastewater treatment sludge gasification by artificial neural network modeling  

Science Journals Connector (OSTI)

Abstract This paper reports on the calorific value of synthetic gas (syngas) produced by gasification of dewatered sludge derived from treatment of tannery wastewater. Proximate and ultimate analyses of samples were performed. Thermochemical conversion alters the chemical structure of the waste. Dried air was used as a gasification agent at varying flow rates, which allowed the feedstock to be quickly converted into gas by means of different heterogeneous reactions. A lab-scale updraft fixed-bed steel reactor was used for thermochemical conversion of sludge samples. Artificial neural network (ANN) modeling techniques were used to observe variations in the syngas related to operational conditions. Modeled outputs showed that temporal changes of model predictions were in close accordance with real values. Correlation coefficients (r) showed that the ANN used in this study gave results with high sensitivity.

Multimedia sampling for dioxin at a strip mine reclaimed with sludge from bleached kraft wastewater treatment  

SciTech Connect (OSTI)

This paper reports that mead conducted a two-year dioxin testing program on strip-mined land being reclaimed with sludge from the wastewater treatment plant of its bleached kraft mill. Many different samples were analyzed for both 2,3,7,8-TCDD (or dioxin) and 2,3,7,8-TCDF (or furan). The study included biodiversity studies to determine the total environmental impact. The results indicate that the sludge is an excellent reclamation material that improves the biodiversity at the site. The tracer dioxin in the sludge does not exhibit any significant migration or bioavailability when used for reclaiming strip mines. These findings differ from assumptions sometimes used in assessing the environmental risks of dioxin.

The production of biofuel and bioelectricity associated with wastewater treatment by green algae  

Science Journals Connector (OSTI)

Abstract This study describes algal biofuel production, bioelectricity generation and wastewater treatment using Leptolyngbya sp. JPMTW1 (KF977831). The experiments were conducted in an AMFC (Algal Microbial Fuel Cell) photobioreactor (single-chamber). The pH, EC (electrical conductivity), COD (chemical oxygen demand) and TDS (total dissolved solids) decreased from 8.01 to 7.0, 982 to 854 (mS/cm), 255 to 112 (mg/L) and 490427 (mg/L), respectively, over course of 7 days. Biomass production, rate of biomass production, chlorophyll a, b and total chlorophyll content increased with increasing time and were observed to be 3300mg/L, 471.42mg/L/day, 0.981mg/L, 0.173mg/L and 1.156mg/L after 7 days. Lipid production and rate of lipid production were 1068.383mg/g dry wt. biomass and 152.62mg/g dry biomass/day. FTIR (Fourier transform infrared) spectra revealed the presence of protein, lipid, \\{FAs\\} (fatty acids), triglycerides and ester functional groups. FAME (fatty acid methyl esters) profile revealed the presence of C16:0, C18:2n-6, C18:1 and C16:1. The generation of electric potential by Leptolyngbya sp. JPMTW1 increased significantly (p?0.05) from 0.0211 to 0.264mV within 7 days. The maximum power density (0.008mW/cm2) was obtained at cell potential at 12mV. This study shows that simultaneous production of biofuel, bioelectricity and wastewater treatment is possible by Leptolyngbya sp. JPMTW1.

Westinghouse Cementation Facility of Solid Waste Treatment System - 13503  

SciTech Connect (OSTI)

During NPP operation, several waste streams are generated, caused by different technical and physical processes. Besides others, liquid waste represents one of the major types of waste. Depending on national regulation for storage and disposal of radioactive waste, solidification can be one specific requirement. To accommodate the global request for waste treatment systems Westinghouse developed several specific treatment processes for the different types of waste. In the period of 2006 to 2008 Westinghouse awarded several contracts for the design and delivery of waste treatment systems related to the latest CPR-1000 nuclear power plants. One of these contracts contains the delivery of four Cementation Facilities for waste treatment, s.c. 'Follow on Cementations' dedicated to three locations, HongYanHe, NingDe and YangJiang, of new CPR-1000 nuclear power stations in the People's Republic of China. Previously, Westinghouse delivered a similar cementation facility to the CPR-1000 plant LingAo II, in Daya Bay, PR China. This plant already passed the hot functioning tests successfully in June 2012 and is now ready and released for regular operation. The 'Follow on plants' are designed to package three 'typical' kind of radioactive waste: evaporator concentrates, spent resins and filter cartridges. The purpose of this paper is to provide an overview on the Westinghouse experience to design and execution of cementation facilities. (authors)

Use advanced methods to treat wastewater  

SciTech Connect (OSTI)

Common sense guidelines offer plausible, progressive techniques to treat wastewater. Because current and pending local, state and federal regulations are ratcheting lower effluent discharge limits, familiar treatment methods, such as biological, don't meet new restrictions. Now operating facilities must combine traditional methods with advanced remedial options such as thermal, physical, electro and chemical treatments. these new techniques remove organics, metals, nonhazardous dissolved salts, etc., but carry higher operating and installation costs. Due to tighter effluent restrictions and pending zero-discharge initiatives, managers of operating facilities must know and understand the complexity, composition and contaminant concentration of their wastewaters. No one-size-fits-all solution exists. However, guidelines can simplify decision making and help operators nominate the most effective and economical strategy to handle their waste situation. The paper describes the common treatment and the importance of alternatives, then describes biological, electro, physical, thermal, and chemical treatments.

Mechanism of degradation of wool wax in the anaerobic treatment of woolscouring wastewater  

Science Journals Connector (OSTI)

Results of the anaerobic digestion of a woolscouring wastewater treatment and some considerations about the anaerobic degradation mechanisms of wool wax, are presented. A 57 live anaerobic baffled reactor (ABR) was operated with woolscouring effluent. When organic load varied from 3 to 5 kg COD/m3 d, COD and grease removal ranged from 40 to 55% and 50 to 65%, respectively. With centrifuged effluent, COD removal was 45% to 60%. A 300 m3 ABR was built and operated during two years based on the previous laboratory results. COD removal was between 45% to 18% with organic load of 3 to 10 kg COD/m3 d. With centrifuged effluent, COD efficiencies ranged between 72% and 47%. No inhibition by long chain fatty acids was observed. Considering the results of grease content determination and TLC analysis in both reactors, it could be assumed that wool wax is hydrolyzed forming sterols and free fatty acids and that free fatty acids are degraded while sterols are accumulated in the sludge.

A methodology to estimate greenhouse gases emissions in Life Cycle Inventories of wastewater treatment plants  

SciTech Connect (OSTI)

The main objective of this paper is to present the Direct Emissions Estimation Model (DEEM), a model for the estimation of CO{sub 2} and N{sub 2}O emissions from a wastewater treatment plant (WWTP). This model is consistent with non-specific but widely used models such as AS/AD and ASM no. 1 and presents the benefits of simplicity and application over a common WWTP simulation platform, BioWin Registered-Sign , making it suitable for Life Cycle Assessment and Carbon Footprint studies. Its application in a Spanish WWTP indicates direct N{sub 2}O emissions to be 8 times larger than those associated with electricity use and thus relevant for LCA. CO{sub 2} emissions can be of similar importance to electricity-associated ones provided that 20% of them are of non-biogenic origin. - Highlights: Black-Right-Pointing-Pointer A model has been developed for the estimation of GHG emissions in WWTP. Black-Right-Pointing-Pointer Model was consistent with both ASM no. 1 and AS/AD. Black-Right-Pointing-Pointer N{sub 2}O emissions are 8 times more relevant than the one associated with electricity. Black-Right-Pointing-Pointer CO{sub 2} emissions are as important as electricity if 20% of it is non-biogenic.

Fate of anthropogenic cyclic volatile methylsiloxanes in a wastewater treatment plant  

Science Journals Connector (OSTI)

Abstract The fate of cyclic volatile methylsiloxanes (cVMS) octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6) was evaluated in a typical secondary activated sludge wastewater treatment plant (WWTP). Water samples (influent, primary effluent, and final effluent) and sludge (primary sludge and waste activated sludge) samples were collected at overnight low, morning high, afternoon low, and evening high flows. Concentrations of cVMS in influents fluctuated with the influent flows, ranging from 0.166 to 1.13?gL?1, 3.4719.3?gL?1, and 0.4463.87?gL?1 for D4, D5, and D6, respectively. Mass balance analysis of cVMS showed the average mass of D4, D5, and D6 entering and exiting the plant in influent and effluent, respectively, were 109gd?1, 2050gd?1, 280gd?1, and 1.41gd?1, 27.0gd?1, 1.90gd?1. The total removal efficiency of cVMS was >96%. To elucidate their detailed removal mechanisms, Mackay's fugacity-based treatment plant model was used to simulate the fate of cVMS through the WWTP. Due to the unusual combination of high hydrophobicity and volatility of cVMS, volatilization in the aeration tank and adsorption to sludge were the two main pathways of cVMS removal from water in this WWTP based on the experimental and modeled results. The morning and evening high influent mass flows contributed almost equally at approximately 40% of the total daily cVMS mass, with D5 accounting for the majority of this daily loading.

Occurrence, fate and ecotoxicological assessment of pharmaceutically active compounds in wastewater and sludge from wastewater treatment plants in Chongqing, the Three Gorges Reservoir Area  

Science Journals Connector (OSTI)

Abstract The occurrence, removal and ecotoxicological assessment of 21 pharmaceutically active compounds (PhACs) including antibiotics, analgesics, antiepileptics, antilipidemics and antihypersensitives, were studied at four municipal wastewater treatment plants (WWTP) in Chongqing, the Three Gorges Reservoir Area. Individual treatment unit effluents, as well as primary and secondary sludge, were sampled and analyzed for the selected PhACs to evaluate their biodegradation, persistence and partitioning behaviors. PhACs were identified and quantified using high performance liquid chromatography/tandem mass spectrometry after solid-phase extraction. All the 21 analyzed PhACs were detected in wastewater and the target PhACs except acetaminophen, ibuprofen and gemfibrozil, were also found in sludge. The concentrations of the antibiotics and SVT were comparable to or even higher than those reported in developed countries, while the case of other target PhACs was opposite. The elimination of PhACs except acetaminophen was incomplete and a wide range of elimination efficiencies during the treatment were observed, i.e. from negative removal to 99.5%. The removal of PhACs was insignificant in primary and disinfection processes, and was mainly achieved during the biological treatment. Based on the mass balance analysis, biodegradation is believed to be the primary removal mechanism, whereas only about 1.5% of the total mass load of the target PhACs was removed by sorption. Experimentally estimated distribution coefficients (<500L/kg, with a few exceptions) also indicate that biodegradation/transformation was responsible for the removal of the target PhACs. Ecotoxicological assessment indicated that the environment concentrations of single compounds (including sulfadiazine, sulfamethoxazole, ofloxacin, azithromycin and erythromycin-H2O) in effluent and sludge, as well as the mixture of the 21 detected PhACs in effluent, sludge and receiving water had a significant ecotoxicological risk to algae. Therefore, further control of PhACs in effluent and sludge is required before their discharge and application to prevent their introduction into the environment.

Occurrence and fate of eleven classes of antibiotics in two typical wastewater treatment plants in South China  

Science Journals Connector (OSTI)

Abstract Wastewater treatment plants (WWTPs) are regarded as one of the most important sources of antibiotics in the environment. Two sampling campaigns over a period of one year in two wastewater treatment plants (plant A: activated sludge with chlorination, and plant B: oxidation ditch with UV) of Guangdong Province, China were carried out to assess the occurrence and fate of 11 classes of 50 antibiotics. The wastewater samples were extracted by Oasis HLB cartridges (6mL, 500mg), while the solid samples (sludge and suspended solid matter) were extracted by ultrasonic-assisted extraction with solvents (acetonitrile and citric acid buffer), followed by an enrichment and clean-up step with solid-phase extraction using SAX-HLB cartridges in tandem. The results showed the presence of 20 and 17 target compounds in the influents and effluents, respectively, at the concentrations ranging from low ng/L to a few ?g/L. Sulfamethoxazole, norfloxacin, ofloxacin, anhydro erythromycin and trimethoprim were most frequently detected in the \\{WWTPs\\} wastewaters. Twenty-one antibiotics were found in the sewage sludge from the two \\{WWTPs\\} at the concentrations up to 5800ng/g, with tetracycline, oxytetracycline, norfloxacin and ofloxacin being the predominant antibiotics. The total mass loads of antibiotics per capita in the two plants ranged from 494 to 901?g/d/inhabitant (672182?g/d/inhabitant) in the influents, from 130 to 238?g/d/inhabitant (17545?g/d/inhabitant) in the effluents and from 107 to 307?g/d/inhabitant (19187.9?g/d/inhabitant) in the dewatered sludge, respectively. The aqueous removals for sulfonamides, macrolides, trimethoprim, lincomycin and chloramphenicol in the \\{WWTPs\\} were mainly attributed to the degradation processes, while those for tetracyclines and fluoroquinolones were mainly due to the adsorption onto sludge.

BIO?REFINERIES: BIOPROCESS TECHNOLOGIES FOR WASTE?WATER TREATMENT, ENERGY AND PRODUCT VALORIZATION  

Science Journals Connector (OSTI)

Increasing pressure is being exerted on communities and nations to source energy from forms other than fossil fuels. Also potable water is becoming a scarce resource in many parts of the world and there remains a large divide in the demand and utilization of plant products derived from genetically modified organisms (GMOs) and non?GMOs. The most extensive user and manager of terrestrial ecosystems is agriculture which is also the de facto steward of natural resources. As stated by Miller (2008) no other industry or institution comes close to the comparative advantage held for this vital responsibility while simultaneously providing food fiber and other biology?based products including energy. Since modern commercial agriculture is transitioning from the production of bulk commodities to the provision of standardized products and specific?attribute raw materials for differentiated markets we can argue that processes such as mass cultivation of microalgae and the concept of bio?refineries be seen as part of a new agronomy. EBRU is currently exploring the integration of bioprocess technologies using microalgae as biocatalysts to achieve waste?water treatment water polishing and endocrine disruptor (EDC) removal sustainable energy production and exploitation of the resultant biomass in agriculture as foliar fertilizer and seed coatings and for commercial extraction of bulk commodities such as bio?oils and lecithin. This presentation will address efforts to establish a fully operational solar?driven microalgae bio?refinery for use not only in waste remediation but to transform waste and biomass to energy fuels and other useful materials (valorisation) with particular focus on environmental quality and sustainability goals.

Stripping of organic compounds from wastewater as an auxiliary fuel of regenerative thermal oxidizer  

Science Journals Connector (OSTI)

Organic solvents with different volatilities are widely used in various processes and generate air and water pollution problems. In the cleaning processes of electronics industries, most volatile organic compounds (VOCs) are vented to air pollution control devices while most non-volatile organic solvents dissolve in the cleaning water and become the major sources of COD in wastewater. Discharging a high-COD wastewater stream to wastewater treatment facility often disturbs the treatment performance. A pretreatment of the high-COD wastewater is therefore highly desirable. This study used a packed-bed stripping tower in combination with a regenerative thermal oxidizer to remove the COD in the wastewater from a printed circuit board manufacturing process and to utilize the stripped organic compounds as the auxiliary fuel of the RTO. The experimental results showed that up to 45% of the COD could be removed and 66% of the RTO fuel could be saved by the combined treatment system.

Use of Treated Municipal Wastewater as Power Plant Cooling System Makeup Water: Tertiary Treatment versus Expanded Chemical Regimen for Recirculating Water Quality Management  

SciTech Connect (OSTI)

Treated municipal wastewater is a common, widely available alternative source of cooling water for thermoelectric power plants across the U.S. However, the biodegradable organic matter, ammonia-nitrogen, carbonate and phosphates in the treated wastewater pose challenges with respect to enhanced biofouling, corrosion, and scaling, respectively. The overall objective of this study was to evaluate the benefits and life cycle costs of implementing tertiary treatment of secondary treated municipal wastewater prior to use in recirculating cooling systems. The study comprised bench- and pilot-scale experimental studies with three different tertiary treated municipal wastewaters, and life cycle costing and environmental analyses of various tertiary treatment schemes. Sustainability factors and metrics for reuse of treated wastewater in power plant cooling systems were also evaluated. The three tertiary treated wastewaters studied were: secondary treated municipal wastewater subjected to acid addition for pH control (MWW_pH); secondary treated municipal wastewater subjected to nitrification and sand filtration (MWW_NF); and secondary treated municipal wastewater subjected nitrification, sand filtration, and GAC adsorption (MWW_NFG). Tertiary treatment was determined to be essential to achieve appropriate corrosion, scaling, and biofouling control for use of secondary treated municipal wastewater in power plant cooling systems. The ability to control scaling, in particular, was found to be significantly enhanced with tertiary treated wastewater compared to secondary treated wastewater. MWW_pH treated water (adjustment to pH 7.8) was effective in reducing scale formation, but increased corrosion and the amount of biocide required to achieve appropriate biofouling control. Corrosion could be adequately controlled with tolytriazole addition (4-5 ppm TTA), however, which was the case for all of the tertiary treated waters. For MWW_NF treated water, the removal of ammonia by nitrification helped to reduce the corrosivity and biocide demand. Also, the lower pH and alkalinity resulting from nitrification reduced the scaling to an acceptable level, without the addition of anti-scalant chemicals. Additional GAC adsorption treatment, MWW_NFG, yielded no net benefit. Removal of organic matter resulted in pitting corrosion in copper and cupronickel alloys. Negligible improvement was observed in scaling control and biofouling control. For all of the tertiary treatments, biofouling control was achievable, and most effectively with pre-formed monochloramine (2-3 ppm) in comparison with NaOCl and ClO2. Life cycle cost (LCC) analyses were performed for the tertiary treatment systems studied experimentally and for several other treatment options. A public domain conceptual costing tool (LC3 model) was developed for this purpose. MWW_SF (lime softening and sand filtration) and MWW_NF were the most cost-effective treatment options among the tertiary treatment alternatives considered because of the higher effluent quality with moderate infrastructure costs and the relatively low doses of conditioning chemicals required. Life cycle inventory (LCI) analysis along with integration of external costs of emissions with direct costs was performed to evaluate relative emissions to the environment and external costs associated with construction and operation of tertiary treatment alternatives. Integrated LCI and LCC analysis indicated that three-tiered treatment alternatives such as MWW_NSF and MWW_NFG, with regular chemical addition for treatment and conditioning and/or regeneration, tend to increase the impact costs and in turn the overall costs of tertiary treatment. River water supply and MWW_F alternatives with a single step of tertiary treatment were associated with lower impact costs, but the contribution of impact costs to overall annual costs was higher than all other treatment alternatives. MWW_NF and MWW_SF alternatives exhibited moderate external impact costs with moderate infrastructure and chemical conditioner dosing, which makes them (especially

The hydrogen peroxide decomposer columns at the 200 Area Effluent Treatment Facility (ETF) have been taken out of service due to ongoing problems with particulate fines and poor destruction performance from the granular activated carbon (GAC) used in the columns. An alternative search was initiated and led to bench scale testing and then pilot scale testing. Based on the bench scale testing three manganese dioxide based catalysts were evaluated in the peroxide destruction pilot column installed at the 300 Area Treated Effluent Disposal Facility. The ten inch diameter, nine foot tall, clear polyvinyl chloride (PVC) column allowed for the same six foot catalyst bed depth as is in the existing ETF system. The flow rate to the column was controlled to evaluate the performance at the same superficial velocity (gpm/ft{sup 2}) as the full scale design flow and normal process flow. Each catalyst was evaluated on peroxide destruction performance and particulate fines capacity and carryover. Peroxide destruction was measured by hydrogen peroxide concentration analysis of samples taken before and after the column. The presence of fines in the column headspace and the discharge from carryover was generally assessed by visual observation. All three catalysts met the peroxide destruction criteria by achieving hydrogen peroxide discharge concentrations of less than 0.5 mg/L at the design flow with inlet peroxide concentrations greater than 100 mg/L. The Sud-Chemie T-2525 catalyst was markedly better in the minimization of fines and particle carryover. It is anticipated the T-2525 can be installed as a direct replacement for the GAC in the peroxide decomposer columns. Based on the results of the peroxide method development work the recommendation is to purchase the T-2525 catalyst and initially load one of the ETF decomposer columns for full scale testing.

Biological Information Document, Radioactive Liquid Waste Treatment Facility  

SciTech Connect (OSTI)

This document is intended to act as a baseline source material for risk assessments which can be used in Environmental Assessments and Environmental Impact Statements. The current Radioactive Liquid Waste Treatment Facility (RLWTF) does not meet current General Design Criteria for Non-reactor Nuclear Facilities and could be shut down affecting several DOE programs. This Biological Information Document summarizes various biological studies that have been conducted in the vicinity of new Proposed RLWTF site and an Alternative site. The Proposed site is located on Mesita del Buey, a mess top, and the Alternative site is located in Mortandad Canyon. The Proposed Site is devoid of overstory species due to previous disturbance and is dominated by a mixture of grasses, forbs, and scattered low-growing shrubs. Vegetation immediately adjacent to the site is a pinyon-juniper woodland. The Mortandad canyon bottom overstory is dominated by ponderosa pine, willow, and rush. The south-facing slope was dominated by ponderosa pine, mountain mahogany, oak, and muhly. The north-facing slope is dominated by Douglas fir, ponderosa pine, and oak. Studies on wildlife species are limited in the vicinity of the proposed project and further studies will be necessary to accurately identify wildlife populations and to what extent they utilize the project area. Some information is provided on invertebrates, amphibians and reptiles, and small mammals. Additional species information from other nearby locations is discussed in detail. Habitat requirements exist in the project area for one federally threatened wildlife species, the peregrine falcon, and one federal candidate species, the spotted bat. However, based on surveys outside of the project area but in similar habitats, these species are not expected to occur in either the Proposed or Alternative RLWTF sites. Habitat Evaluation Procedures were used to evaluate ecological functioning in the project area.

The biodegradation of olive oil and the treatment of lipid-rich wool scouring wastewater under aerobic thermophilic conditions  

Science Journals Connector (OSTI)

The biodegradation of olive oil and the treatment of the lipid-rich wool scouring wastewater were studied under aerobic thermophilic (65C) conditions using the newly isolated strain Bacillus thermoleovorans IHI-91. In a continuously operated laboratory-scale stirred-tank reactor olive oil was degraded to more than 90% at a residence time of 2h with a maximum volumetric degradation rate of 900mgl?1h?1. A relatively high maximum biomass yield of 1.05g dry cell weight per g olive oil consumed was measured and a maintenance coefficient of 0.04g olive oil(g DCW)?1h?1 was calculated from steady-state data. A severe growth inhibition was observed when the feed olive oil concentration was increased to more than 4gl?1. Lipid removal from the highly loaded wool scouring wastewater (COD of 77000mgl?1) was 2030% at a residence time of 1020h while the COD removal was 1520%. GC-MS analysis revealed that longchain fatty acids up to C18 were efficiently degraded while degradation of the predominant sterol-fraction of the wool grease was not detected. The high concentrations of volatile fatty acids (60mM acetic acid, 13mM propionic acid) present in the wastewater were completely removed even at residence times of 2h. Compared with data from mesophilic processes the lipid degradation rates obtained under thermophilic conditions are extremely high.

Fate of As, Se, and Hg in a Passive Integrated System for Treatment of Fossil Plant Wastewater  

SciTech Connect (OSTI)

TVA is collaborating with EPRI and DOE to demonstrate a passive treatment system for removing SCR-derived ammonia and trace elements from a coal-fired power plant wastewater stream. The components of the integrated system consist of trickling filters for ammonia oxidation, reaction cells containing zero-valent iron (ZVI) for trace contaminant removal, a settling basin for storage of iron hydroxide floc, and anaerobic vertical-flow wetlands for biological denitrification. The passive integrated treatment system will treat up to 0.25 million gallons per day (gpd) of flue gas desulfurization (FGD) pond effluent, with a configuration requiring only gravity flow to obviate the need for pumps. The design of the system will enable a comparative evaluation of two parallel treatment trains, with and without the ZVI extraction trench and settling/oxidation basin components. One of the main objectives is to gain a better understanding of the chemical transformations that species of trace elements such as arsenic, selenium, and mercury undergo as they are treated in passive treatment system components with differing environmental conditions. This progress report details the design criteria for the passive integrated system for treating fossil power plant wastewater as well as performance results from the first several months of operation. Engineering work on the project has been completed, and construction took place during the summer of 2005. Monitoring of the passive treatment system was initiated in October 2005 and continued until May 18 2006. The results to date indicate that the treatment system is effective in reducing levels of nitrogen compounds and trace metals. Concentrations of both ammonia and trace metals were lower than expected in the influent FGD water, and additions to increase these concentrations will be done in the future to further test the removal efficiency of the treatment system. In May 2006, the wetland cells were drained of FGD water, refilled with less toxic ash pond water, and replanted due to low survival rates from the first planting the previous summer. The goals of the TVA-EPRI-DOE collaboration include building a better understanding of the chemical transformations that trace elements such as arsenic, selenium, and mercury undergo as they are treated in a passive treatment system, and to evaluate the performance of a large-scale replicated passive treatment system to provide additional design criteria and economic factors.

Radioactive Liquid Waste Treatment Facility Discharges in 2011  

SciTech Connect (OSTI)

This report documents radioactive discharges from the TA50 Radioactive Liquid Waste Treatment Facilities (RLWTF) during calendar 2011. During 2011, three pathways were available for the discharge of treated water to the environment: discharge as water through NPDES Outfall 051 into Mortandad Canyon, evaporation via the TA50 cooling towers, and evaporation using the newly-installed natural-gas effluent evaporator at TA50. Only one of these pathways was used; all treated water (3,352,890 liters) was fed to the effluent evaporator. The quality of treated water was established by collecting a weekly grab sample of water being fed to the effluent evaporator. Forty weekly samples were collected; each was analyzed for gross alpha, gross beta, and tritium. Weekly samples were also composited at the end of each month. These flow-weighted composite samples were then analyzed for 37 radioisotopes: nine alpha-emitting isotopes, 27 beta emitters, and tritium. These monthly analyses were used to estimate the radioactive content of treated water fed to the effluent evaporator. Table 1 summarizes this information. The concentrations and quantities of radioactivity in Table 1 are for treated water fed to the evaporator. Amounts of radioactivity discharged to the environment through the evaporator stack were likely smaller since only entrained materials would exit via the evaporator stack.

Determining the ecological viability of constructed wetlands for the treatment of oil sands wastewater  

SciTech Connect (OSTI)

To determine the conditions for optimal degradation of naphthenic acids (C{sub n}H{sub 2n+z}O{sub 2}), the most toxic component of oil sands wastewater, the authors have monitored the mineralization of 2 representative naphthenic acids (NA), U-{sup 14}C-palmitic acid (linear, Z = 0) and 8-{sup 14}C-decahydro-2-naphthoic acid (bicyclic, Z = {minus}4) under varying conditions of temperature, phosphate and oxygen. The radiolabeled NA was added to biometer flasks containing wastewater {+-} amendments and evolved {sup 14}C-CO{sub 2} was trapped in a side arm and counted by LSC. The results indicate that low temperature (5 C) and anaerobiasis greatly inhibited NA degradation over the four week incubation period. Addition of phosphate (as buffered KP{sub i}) significantly increased {sup 14}C-CO{sub 2} production for both Z = 0 and Z = {minus}4 compounds; however, the subsequent high microbial growth rates also decreased PO{sub 2} which limited NA mineralization. Effluent toxicity was monitored at week 0 and week 4 using Microtox and fathead minnow tests. Although there was increased survival of fathead minnows in the phosphate-amended effluent, the IC{sub 20} values of the Microtox assay showed no improvement in either the phosphate-treated or untreated effluents. These results show that naphthenic acid analogues are readily degraded by indigenous microorganisms in oil sands wastewater and that phosphate addition accelerated the mineralization of these compounds if PO{sub 2} remained high.

Chapter 7 - Urban Wastewater Treatment for Recycling and Reuse in Industrial Applications: Indian Scenario  

Science Journals Connector (OSTI)

Abstract Urban wastewater management has become a challenge in many countries because infrastructure development and regulations have not kept pace with population growth and urbanization. This chapter focuses on urban wastewater management and the possible use of treated water for industrial applications in India. The figures on Indias annual urban population are rising and expected to reach about 600 million by 2030, making India more peri-urban than rural. It is realised that Indian industry has not taken a neutral stance on the required quality and quantity of water. The current national water share for Indian industry is only about 8%, which is far lower than in developed countries with respect to higher reuse and recycling applications. However, the water share of Indian industry will be growing along with the growing GDP. According to a recent Industry/Commerce & Government assessment, the water requirement for industrial use will increase from the current 30 billion m3 to-120 billionm3 by 2025. India is already an almost water-stressed country. The huge water demand of industry can be balanced by recycling and reusing urban wastewater, which would also provide an opportunity for the growth of Indian industry should this type of program be adopted. It would be possible to reuse 4050% of secondary sewage for industrial and indirect potable use. If the sustainability of resources was maintained in light of increasing industrial water demand, the present reuse of less than 8% would be increased to 3040% toward the projected water demand of 2030. Industrial water production from secondary sewage of urban and semi-urban areas can increase the water availability to Indian industrial sectors by establishing a joint municipalindustrial collaboration.

Identification and treatment of lithium as the primary toxicant in a groundwater treatment facility effluent  

SciTech Connect (OSTI)

{sup 6}Li is used in manufacturing nuclear weapons, shielding, and reactor control rods. Li compounds have been used at DOE facilities and Li-contaminated waste has historically been land disposed. Seep water from burial grounds near Y-12 contain small amounts of chlorinated hydrocarbons, traces of PCBs, and 10-19 mg/L Li. Seep treatment consists of oil-water separation, filtration, air stripping, and carbon adsorption. Routine biomonitoring tests using fathead minnows and {ital Ceriodaphnia}{ital dubia} are conducted. Evaluation of suspected contaminants revealed that toxicity was most likely due to Li. Laboratory tests showed that 1 mg Li/L reduced the survival of both species; 0.5 mg Li/L reduced {ital Ceriodaphnia} reproduction and minnow growth. However, the toxicity was greatly reduced in presence of sodium (up to 4 mg Li/L, Na can fully negate the toxic effect of Li). Because of the low Na level discharged from the treatment facility, Li removal from the ground water was desired. SuperLig{reg_sign} columns were used (Li-selective organic macrocycle bonded to silica gel). Bench-scale tests showed that the material was very effective for removing Li from the effluent, reducing the toxicity.

Energy-efficient evaporators can cut operating costs for wastewater treatment, reuse  

SciTech Connect (OSTI)

High-efficiency evaporators can substantially lower the costs of recycling water, separating and reducing waste, and reclaiming industrial byproducts. Although capital costs run higher than conventional, stream-driven systems, energy efficient designs can allow users to recoup those costs over time and provide significant, ongoing utility savings. This is especially true in applications in which evaporation requirements are more than 75,000 pounds per hour, and steam costs exceed $3 per 1,000 pounds. In conventional, multistage evaporators, vapor resulting from wastewater evaporation is reused as a heating agent to effect further evaporation, but fresh steam must be added continuously to the system to maintain adequate temperature and pressure--two factors critical to evaporation. In contrast, three energy-efficient designs maintain temperature and pressure by recycling otherwise wasted resources, thereby greatly reducing or eliminating steam costs and other utility expenses.

Treatment of reactive dyes and textile finishing wastewater using Fenton's oxidation for reuse  

Science Journals Connector (OSTI)

Fenton's oxidation (FO) was used to decolourise and degrade some reactive dyes (Remazol Black 5, Remazol Red, Remazol Blue, Remazol Yellow) and raw textile finishing industry effluents (S1, S2, S3) containing mainly reactive dyes. The operational conditions for pH varied between 2.5 and 4.0 while temperature ranged from 30°C to 50°C. The concentrations of FeSO4 and H2O2 varied to a wide range (200??600 mg/l of FeSO4, 300??1000 mg/l of H2O2) depending on the type of the dyes and their mixture and textile additives used in the process. FO is highly effective for colour removal (>99%) for reactive dyes and (87??94%) for textile finishing wastewater. It can be applied as a pretreatment and the remaining total dissolved solids (TDS) can be removed by an additional advanced process, e.g. membrane process.

and air emission implications of a decentralized wastewater system and air emission implications of a decentralized wastewater system Title Energy and air emission implications of a decentralized wastewater system Publication Type Journal Article Year of Publication 2012 Authors Shehabi, Arman, Jennifer R. Stokes, and Arpad Horvath Journal Environmental Research Letters Volume 7 Issue 2 Abstract Both centralized and decentralized wastewater systems have distinct engineering, financial and societal benefits. This paper presents a framework for analyzing the environmental effects of decentralized wastewater systems and an evaluation of the environmental impacts associated with two currently operating systems in California, one centralized and one decentralized. A comparison of energy use, greenhouse gas emissions and criteria air pollutants from the systems shows that the scale economies of the centralized plant help lower the environmental burden to less than a fifth of that of the decentralized utility for the same volume treated. The energy and emission burdens of the decentralized plant are reduced when accounting for high-yield wastewater reuse if it supplants an energy-intensive water supply like a desalination one. The centralized facility also reduces greenhouse gases by flaring methane generated during the treatment process, while methane is directly emitted from the decentralized system. The results are compelling enough to indicate that the life-cycle environmental impacts of decentralized designs should be carefully evaluated as part of the design process.

Reciprocating Constructed Wetlands for Treating Industrial, Municipal, and Agricultural Wastewater  

E-Print Network [OSTI]

For many rural communities, treating domestic wastewater efficiently and cost-effectively is a challenging task. Environmental issues, financing of construction costs, and the bottom-line cost to the consumer complicate this effort. Increasingly stringent discharge standards have resulted in a growing number of permit violations from small, conventional treatment systems. Many rural communities have discovered that their existing systems (e.g., facultative lagoons) provided excellent service in the past but have become obsolete due to new discharge standards. These communities simply cannot afford to own and operate the highly sophisticated tertiary treatment facilities these new regulations require. As a result, funding agencies have looked more favorably to regional solutions that can achieve consistent, high-quality discharge. In most cases, the regional solution is a centralized treatment facility to which surrounding communities pump their sewage. In many instances, communities must pump extremely long distances to reach the regional treatment facility. This means that communities, and, therefore, funding agencies, are putting most of their money into pumps and piping instead of treatment. What small rural communities need is a decentralized wastewater treatment system that is inexpensive to construct, simple to operate, and achieves consistently high levels of discharge quality, even with small flows. Having such a system would allow a paradigm shift whereby funding agencies could support decentralized treatment and regional management of numerous decentralized treatment systems.

SciTech Connect (OSTI)

This effort addressed an evaluation of human machine interfaces (HMIs) in Room TA-50-1-60/60A of the Radioactive Liquid Waste Treatment Facility (RLWTF). The evaluation was performed in accordance with guidance outlined in DOE-STD-3009, DOE Standard Preparation Guide for U.S. Department of Energy Nonreactor Nuclear Facility Documented Safety Analyses, 2006 [DOE 2006]. Specifically, Chapter 13 of DOE 2006 highlights the 10 CFR 830, Nuclear Safety Management, 2012, [CFR 2012] and DOE G 421.1-2 [DOE 2001a] requirements as they relate to the human factors process and, in this case, the safety of the RLWTF. The RLWTF is a Hazard Category 3 facility and, consequently, does not have safety-class (SSCs). However, safety-significant SSCs are identified. The transuranic (TRU) wastewater tanks and associated piping are the only safety-significant SSCs in Rooms TA-50-1-60/60A [LANL 2010]. Hence, the human factors evaluation described herein is only applicable to this particular assemblage of tanks and piping.

Treatment of municipal wastewater reverse osmosis concentrate using UVC-LED/H2O2 with and without coagulation pre-treatment  

Science Journals Connector (OSTI)

Abstract The potential of a prototype batch reactor using ultraviolet light emitting diodes (UVC-LEDs) which emit at 255nm in conjunction with H2O2 for the treatment of a highly saline (electrical conductivity ?22mS/cm; DOC 3237.5mg/L) municipal wastewater reverse osmosis concentrate was investigated. Mineralization of organic content (measured as DOC) was low (22%) due to the low fluence rate (0.14mW/cm2), however, a large reduction in colour (94%) and A254 (75%) occurred after delivering a UV fluence of 48נ103mJ/cm2 at the original pH of 8.3. Fairly similar results were obtained at pH 7, but the reduction of DOC increased at lower pH with 38% and 36% achieved at pH 4 and 5, respectively. Similar trends were observed for colour and A254 reduction. These results, in conjunction with excitationemission matrix spectra, biological dissolved organic carbon (BDOC) assay and apparent molecular size distribution, demonstrated that the prototype system led to the breakdown of the chromophore bonds and thus changes in the molecular structure, and degradation of high molecular weight (MW) compounds to low MW compounds. Coagulation (1.5 and 3mmolL?1 Al3+ at pH 5) led to a significant reduction of DOC (3438%), colour (5066%) and A254 (4754%), and subsequent UVC/H2O2 treatment led to further reduction in these parameters. For a target DOC reduction of 15mg/L, the EE/O was 15kWh/m3 when coagulation was used as pre-treatment to the UVC/H2O2 treatment (UV fluence 36נ103mJ/cm2) and it reduced to less than half after biological treatment (as BDOC assay). This study demonstrated the potential of UV-LEDs as an alternative UV source for degrading the organic matter in ROC using advanced oxidation.

Mass balance for wastewater nitrogen in the Central ArizonaPhoenix ecosystem  

Science Journals Connector (OSTI)

A complete nitrogen mass balance for all wastewater generated in the Central ArizonaPhoenix ecosystem was developed using data from the 18 largest wastewater treatment plants (99% of flow). Components included total N in raw wastewater, denitrification in wastewater treatment plants, biosolids production, and effluent (reuse, recharge, and discharge). Denitrification and biosolids production remove 81% of wastewater N. Nearly all biosolids are recycled to cotton fields within the ecosystem. Most effluent is recycled within the ecosystem. As the result of wastewater management practices developed to reuse wastewater, wastewater N is either deliberately volatilized or accumulates within the system; only 4% of the original wastewater N is exported via the Gila River.

How environmentally significant is water consumption during wastewater treatment?: Application of recent developments in LCA to WWT technologies used at 3 contrasted geographical locations  

Science Journals Connector (OSTI)

Abstract Environmental impact assessment models are readily available for the assessment of pollution-related impacts in life cycle assessment (LCA). These models have led to an increased focus on water pollution issues resulting in numerous LCA studies. Recently, there have been significant developments in methods assessing freshwater use. These improvements widen the scope for the assessment of wastewater treatment (WWT) technologies, now allowing us to apprehend, for the first time, a combination of operational (energy and chemicals use), qualitative (environmental pollution) and quantitative (water deprivation) issues in wastewater treatment. This enables us to address the following question: Is water consumption during wastewater treatment environmentally significant compared to other impacts? To answer this question, a standard life cycle inventory (LCI) was performed with a focus on consumptive water uses at plant level, where several WWT technologies were operating, in different climatic conditions. The impacts of water consumption were assessed by integrating regionalized characterization factors for water deprivation within an existing life cycle impact assessment (LCIA) method. Results at the midpoint level, show that water deprivation impacts are highly variable in relation to the chosen WWT technology (water volume used) and of WWTP location (local water scarcity). At the endpoint level, water deprivation impacts on ecosystem quality and on the resource damage categories are significant for WWT technologies with great water uses in water-scarce areas. Therefore, our study shows the consideration of water consumption-related impacts is essential and underlines the need for a greater understanding of the water consumption impacts caused by WWT systems. This knowledge will help water managers better mitigate local water deprivation impacts, especially in selecting WWT technologies suitable for arid and semi-arid areas.

Performance optimization of biological waste treatment by flotation clarification at a chemical manufacturing facility  

SciTech Connect (OSTI)

Air Products and Chemicals, Inc., utilizes a deep-tank activated sludge wastewater treatment system with a dissolved air flotation clarifier (DAF) to effectively treat amine wastes containing residual organics, ammonia-nitrogen and organic nitrogen. The bio-system, a deep tank aeration system, produces a high quality final effluent low in biochemical oxygen demand (BOD), ammonia and organic nitrogen, turbidity and total suspended solids. Prior to installing the DAF, treatment performance was at risk with a gravity clarifier. Waste treatment performance was jeopardized by poor settling bio-flocs and uncontrollable solids-liquid separation problems within the gravity clarifier. The solids settleability problems resulted primarily from mixed liquor nitrogen supersaturation degassing in the clarifier. As a result of the degassing, biomass floated on the gravity clarifier or overflowed the effluent weir. As a result of biomass loss periodically organic carbon and total Kjeldahl nitrogen loadings had to be reduced in order to maintain optimal food-to-mass ratios. As biomass levels dropped within the aeration basin, waste treatment performance was at risk and waste loads had to be decreased causing waste inventories to increase in storage tanks.

Long-term trends of PBDEs, triclosan, and triclocarban in biosolids from a wastewater treatment plant in the Mid-Atlantic region of the US  

Science Journals Connector (OSTI)

Abstract In the US, land application of biosolids has been utilized in government-regulated programs to recycle valuable nutrients and organic carbon that would otherwise be incinerated or buried in landfills. While many benefits have been reported, there are concerns that these practices represent a source of organic micropollutants to the environment. In this study, biosolids samples from a wastewater treatment plant in the Mid-Atlantic region of the US were collected approximately every 2 months over a 7-year period and analyzed for brominated diphenyl ethers (BDE-47, BDE-99, and BDE-209), triclosan, and triclocarban. During the collection period of 20052011, concentrations of the brominated diphenyl ethers BDE-47+BDE-99 decreased by 42%, triclocarban decreased by 47%, but BDE-209 and triclosan remained fairly constant. Observed reductions in contaminant concentrations could not be explained by different seasons or by volumetric changes of wastewaters arriving at the treatment plant and instead may be the result of the recent phaseout of BDE-47 and BDE-99 as well as potential reductions in the use of triclocarban.

Integration of algae cultivation as biodiesel production feedstock with municipal wastewater treatment: Strains screening and significance evaluation of environmental factors  

Science Journals Connector (OSTI)

The objectives of this study are to find the robust strains for the centrate cultivation system and to evaluate the effect of environmental factors including light intensity, lightdark cycle, and exogenous CO2 concentration on biomass accumulation, wastewater nutrient removal and biodiesel production. The results showed that all 14 algae strains from the genus of Chlorella, Haematococcus, Scenedesmus, Chlamydomonas, and Chloroccum were able to grow on centrate. The highest net biomass accumulation (2.01g/L) was observed with Chlorella kessleri followed by Chlorella protothecoides (1.31g/L), and both of them were proved to be capable of mixotrophic growth when cultivated on centrate. Environmental factors had significant effect on algal biomass accumulation, wastewater nutrients removal and biodiesel production. Higher light intensity and exogenous CO2 concentration with longer lighting period promote biomass accumulation, biodiesel production, as well as the removal of chemical oxygen demand and nitrogen, while, lower exogenous CO2 concentration promotes phosphorus removal.

Quantification and characterization of dissolved organic nitrogen in wastewater effluents by electrodialysis treatment followed by size-exclusion chromatography with nitrogen detection  

Science Journals Connector (OSTI)

Abstract Dissolved organic nitrogen (DON) can act as a precursor of nitrogenous disinfection byproducts during oxidative water treatment. Quantification and characterization of DON are still challenging for waters with high concentrations of dissolved inorganic nitrogen (DIN, including ammonia, nitrate and nitrite) relative to total dissolved nitrogen (TDN) due to the cumulative analytical errors of independently measured nitrogen species (i.e., DON=TDN? NO 2 ? ? NO 3 ? ? NH 4 + /NH3) and interference of DIN species to TDN quantification. In this study, a novel electrodialysis (ED)-based treatment for selective DIN removal was developed and optimized with respect to type of ion-exchange membrane, sample pH, and ED duration. The optimized ED method was then coupled with size-exclusion chromatography with organic carbon, UV, and nitrogen detection (SEC-OCD-ND) for advanced DON analysis in wastewater effluents. Among the tested ion-exchange membranes, the PC-AR anion- and CMT cation-exchange membranes showed the lowest DOC loss (17%) during ED treatment of a wastewater effluent at ambient pH (8.0). A good correlation was found between the decrease of the DIN/TDN ratio and conductivity. Therefore, conductivity has been adopted as a convenient way to determine the optimal duration of the ED treatment. In the pH range of 7.08.3, ED treatment of various wastewater effluents with the PC-AR/CMT membranes showed that the relative residual conductivity could be reduced to less than 0.50 (DIN removal >90%; DIN/TDN ratio ?0.60) with lower DOC losses (6%) than the previous dialysis and nanofiltration methods (DOCloss >10%). In addition, the ED method is shorter (0.5h) than the previous methods (>124h). The relative residual conductivity was further reduced to ?0.20 (DIN removal >95%; DIN/TDN ratio?0.35) by increasing the ED duration to 0.7h (DOC loss=8%) for analysis by SEC-OCD-ND, which provided new information on distribution and ratio of organic carbon and nitrogen in different molecular weight fractions of effluent organic matter.

Request for modification of 200 Area effluent treatment facility final delisting  

SciTech Connect (OSTI)

A Delisting Petition submitted to the U.S. Environmental Protection Agency in August 1993 addressed effluent to be generated at the 200 Area Effluent Treatment Facility from treating Hanford Facility waste streams. This Delisting Petition requested that 71.9 million liters per year of treated effluent, bearing the designation 'F001' through 'F005', and/or 'F039' that is derived from 'F001' through 'F005' waste, be delisted. On June 13, 1995, the U.S. Environmental Protection Agency published the final rule (Final Delisting), which formally excluded 71.9 million liters per year of 200 Area Effluent Treatment Facility effluent from ''being listed as hazardous wastes'' (60 FR 31115 now promulgated in 40 CFR 261). Given the limited scope, it is necessary to request a modification of the Final Delisting to address the management of a more diverse multi-source leachate (F039) at the 200 Area Effluent Treatment Facility. From past operations and current cleanup activities on the Hanford Facility, a considerable amount of both liquid and solid Resource Conservation and Recovery Act of 1976 regulated mixed waste has been and continues to be generated. Ultimately this waste will be treated as necessary to meet the Resource Conservation and Recovery Act Land Disposal Restrictions. The disposal of this waste will be in Resource Conservation and Recovery Act--compliant permitted lined trenches equipped with leachate collection systems. These operations will result in the generation of what is referred to as multi-source leachate. This newly generated waste will receive the listed waste designation of F039. This waste also must be managed in compliance with the provisions of the Resource Conservation and Recovery Act.

Occurrence and fate of pharmaceutically active compounds in the largest municipal wastewater treatment plant in Southwest China: Mass balance analysis and consumption back-calculated model  

Science Journals Connector (OSTI)

Abstract The occurrence and fate of twenty-one pharmaceutically active compounds (PhACs) were investigated in different steps of the largest wastewater treatment plant (WWTP) in Southwest China. Concentrations of these PhACs were determined in both wastewater and sludge phases by a high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry. Results showed that 21 target PhACs were present in wastewater and 18 in sludge. The calculated total mass load of PhACs per capita to the influent, the receiving water and sludge were 4.95mgd?1person?1, 889.94?gd?1person?1 and 78.57?gd?1person?1, respectively. The overall removal efficiency of the individual PhACs ranged from negative removal to almost complete removal. Mass balance analysis revealed that biodegradation is believed to be the predominant removal mechanism, and sorption onto sludge was a relevant removal pathway for quinolone antibiotics, azithromycin and simvastatin, accounting for 9.3526.96% of the initial loadings. However, the sorption of the other selected PhACs was negligible. The overall pharmaceutical consumption in Chongqing, China, was back-calculated based on influent concentration by considering the pharmacokinetics of PhACs in humans. The back-estimated usage was in good agreement with usage of ofloxacin (agreement ratio: 72.5%). However, the back-estimated usage of PhACs requires further verification. Generally, the average influent mass loads and back-calculated annual per capita consumption of the selected antibiotics were comparable to or higher than those reported in developed countries, while the case of other target PhACs was opposite.

California Food Processing Industry Wastewater Demonstration Project: Phase I Final Report  

SciTech Connect (OSTI)

Wastewater treatment is an energy-intensive process and electricity demand is especially high during the utilities summer peak electricity demand periods. This makes wastewater treatment facilities prime candidates for demand response programs. However, wastewater treatment is often peripheral to food processing operations and its demand response opportunities have often been overlooked. Phase I of this wastewater demonstration project monitored wastewater energy and environmental data at Bell-Carter Foods, Inc., California's largest olive processing plant. For this monitoring activity the project team used Green Energy Management System (GEMS) automated enterprise energy management (EEM) technologies. This report presents results from data collected by GEMS from September 15, 2008 through November 30, 2008, during the olive harvest season. This project established and tested a methodology for (1) gathering baseline energy and environmental data at an industrial food-processing plant and (2) using the data to analyze energy efficiency, demand response, daily peak load management, and environmental management opportunities at the plant. The Phase I goals were to demonstrate the measurement and interrelationship of electricity demand, electricity usage, and water quality metrics and to estimate the associated CO{sub 2} emissions.

In FY 1993, the Los Alamos National Laboratory Waste Management Group [CST-7 (formerly EM-7)] requested the Probabilistic Risk and Hazards Analysis Group [TSA-11 (formerly N-6)] to conduct a study of the hazards associated with several CST-7 facilities. Among these facilities are the Hazardous Waste Treatment Facility (HWTF), the HWTF Drum Storage Building (DSB), and the Mixed Waste Receiving and Storage Facility (MWRSF), which are proposed for construction beginning in 1996. These facilities are needed to upgrade the Laboratory`s storage capability for hazardous and mixed wastes and to provide treatment capabilities for wastes in cases where offsite treatment is not available or desirable. These facilities will assist Los Alamos in complying with federal and state requlations.

LOW LEVEL LIQUID RADIOACTIVE WASTE TREATMENT AT MURMANSK, RUSSIA: FACILITY UPGRADE AND EXPANSION  

SciTech Connect (OSTI)

Today there exist many almost overfilled storage tanks with liquid radioactive waste in the Russian Federation. This waste was generated over several years by the civil and military utilization of nuclear power. The current waste treatment capacity is either not available or inadequate. Following the London Convention, dumping of the waste in the Arctic seas is no longer an alternative. Waste is being generated from today's operations, and large volumes are expected to be generated from the dismantling of decommissioned nuclear submarines. The US and Norway have an ongoing co-operation project with the Russian Federation to upgrade and expand the capacity of a treatment facility for low level liquid waste at the RTP Atomflot site in Murmansk. The capacity will be increased from 1,200 m{sup 3}/year to 5,000 m{sup 3} /year. The facility will also be able to treat high saline waste. The construction phase will be completed the first half of 1998. This will be followed by a start-up and a one year post-construction phase, with US and Norwegian involvement for the entire project. The new facility will consist of 9 units containing various electrochemical, filtration, and sorbent-based treatment systems. The units will be housed in two existing buildings, and must meet more stringent radiation protection requirements that were not enacted when the facility was originally designed. The US and Norwegian technical teams have evaluated the Russian design and associated documentation. The Russian partners send monthly progress reports to US and Norway. Not only technical issues must be overcome but also cultural differences resulting from different methods of management techniques. Six to eight hour time differentials between the partners make real time decisions difficult and relying on electronic age tools becomes extremely important. Language difficulties is another challenge that must be solved. Finding a common vocabulary, and working through interpreters make the process very vulnerable. Each of these obstacles can be overcome when there is a common goal and vision shared by all parties and adequate funds are provided to accomplish the task. The upgrading and expansion of this facility and the construction of a similar facility on the Far East coast of Russia will enable the Russians to sign the London Convention dumping prohibition. This project is one of the first waste management construction projects in the north-west of Russia with foreign contribution. Its success may open for additional co-operative projects with Russia in the future.

200 Area effluent treatment facility process control plan 98-02  

SciTech Connect (OSTI)

This Process Control Plan (PCP) provides a description of the background information, key objectives, and operating criteria defining Effluent Treatment Facility (ETF) Campaign 98-02 as required per HNF-IP-0931 Section 37, Process Control Plans. Campaign 98-62 is expected to process approximately 18 millions gallons of groundwater with an assumption that the UP-1 groundwater pump will be shut down on June 30, 1998. This campaign will resume the UP-1 groundwater treatment operation from Campaign 97-01. The Campaign 97-01 was suspended in November 1997 to allow RCRA waste in LERF Basin 42 to be treated to meet the Land Disposal Restriction Clean Out requirements. The decision to utilize ETF as part of the selected interim remedial action of the 200-UP-1 Operable Unit is documented by the Declaration of the Record of Decision, (Ecology, EPA and DOE 1997). The treatment method was chosen in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA), the Hanford Federal Facility Agreement and Consent Order (known as the Tri-Party Agreement or TPA), and to the extent practicable, the National Oil and Hazardous Substances Pollution Contingency Plan (NCP).

Analysis of the suitability of DOE facilities for treatment of commercial low-level radioactive mixed waste  

SciTech Connect (OSTI)

This report evaluates the capabilities of the United States Department of Energy`s (DOE`s) existing and proposed facilities to treat 52 commercially generated low-level radioactive mixed (LLMW) waste streams that were previously identified as being difficult-to-treat using commercial treatment capabilities. The evaluation was performed by comparing the waste matrix and hazardous waste codes for the commercial LLMW streams with the waste acceptance criteria of the treatment facilities, as identified in the following DOE databases: Mixed Waste Inventory Report, Site Treatment Plan, and Waste Stream and Technology Data System. DOE facility personnel also reviewed the list of 52 commercially generated LLMW streams and provided their opinion on whether the wastes were technically acceptable at their facilities, setting aside possible administrative barriers. The evaluation tentatively concludes that the DOE is likely to have at least one treatment facility (either existing or planned) that is technically compatible for most of these difficult-to-treat commercially generated LLMW streams. This conclusion is tempered, however, by the limited amount of data available on the commercially generated LLMW streams, by the preliminary stage of planning for some of the proposed DOE treatment facilities, and by the need to comply with environmental statutes such as the Clean Air Act.

Utilization of municipal wastewater for cooling in thermoelectric power plants: Evaluation of the combined cost of makeup water treatment and increased condenser fouling  

SciTech Connect (OSTI)

A methodology is presented to calculate the total combined cost (TCC) of water sourcing, water treatment and condenser fouling in the recirculating cooling systems of thermoelectric power plants. The methodology is employed to evaluate the economic viability of using treated municipal wastewater (MWW) to replace the use of freshwater as makeup water to power plant cooling systems. Cost analyses are presented for a reference power plant and five different tertiary treatment scenarios to reduce the scaling tendencies of MWW. Results indicate that a 550 MW sub-critical coal fired power plant with a makeup water requirement of 29.3 ML/day has a TCC of $3.0 - 3.2 million/yr associated with the use of treated MWW for cooling. (All costs USD 2009). This translates to a freshwater conservation cost of $0.29/kL, which is considerably lower than that of dry air cooling technology, $1.5/kL, as well as the 2020 conservation cost target set by the U.S. Department of Energy, $0.74/kL. Results also show that if the available price of freshwater exceeds that of secondarytreated MWW by more than $0.13-0.14/kL, it can be economically advantageous to purchase secondary MWW and treat it for utilization in the recirculating cooling system of a thermoelectric power plant.

SECONDARY WASTE/ETF (EFFLUENT TREATMENT FACILITY) PRELIMINARY PRE-CONCEPTUAL ENGINEERING STUDY  

SciTech Connect (OSTI)

This pre-conceptual engineering study is intended to assist in supporting the critical decision (CD) 0 milestone by providing a basis for the justification of mission need (JMN) for the handling and disposal of liquid effluents. The ETF baseline strategy, to accommodate (WTP) requirements, calls for a solidification treatment unit (STU) to be added to the ETF to provide the needed additional processing capability. This STU is to process the ETF evaporator concentrate into a cement-based waste form. The cementitious waste will be cast into blocks for curing, storage, and disposal. Tis pre-conceptual engineering study explores this baseline strategy, in addition to other potential alternatives, for meeting the ETF future mission needs. Within each reviewed case study, a technical and facility description is outlined, along with a preliminary cost analysis and the associated risks and benefits.

The Design and Construction of the Advanced Mixed Waste Treatment Facility  

SciTech Connect (OSTI)

The Advanced Mixed Treatment Project (AMWTP) privatized contract was awarded to BNFL Inc. in December 1996 and construction of the main facility commenced in August 2000. The purpose of the advanced mixed waste treatment facility is to safely treat plutonium contaminated waste, currently stored in drums and boxes, for final disposal at the Waste Isolation Pilot Plant (WIPP). The plant is being built at the Idaho National Engineering and Environmental Laboratory. Construction was completed in 28 months, to satisfy the Settlement Agreement milestone of December 2002. Commissioning of the related retrieval and characterization facilities is currently underway. The first shipment of pre-characterized waste is scheduled for March 2003, with AMWTP characterized and certified waste shipments from June 2003. To accommodate these challenging delivery targets BNFL adopted a systematic and focused construction program that included the use of a temporary structure to allow winter working, proven design and engineering principles and international procurement policies to help achieve quality and schedule. The technology involved in achieving the AMWTP functional requirements is primarily based upon a BNFL established pedigree of plant and equipment; applied in a manner that suits the process and waste. This technology includes the use of remotely controlled floor mounted and overhead power manipulators, a high power shredder and a 2000-ton force supercompactor with the attendant glove box suite, interconnections and automated material handling. The characterization equipment includes real-time radiography (RTR) units, drum and box assay measurement systems, drum head space gas sampling / analysis and drum venting, drum coring and sampling capabilities. The project adopted a particularly stringent and intensive pre-installation testing philosophy to ensure that equipment would work safely and reliably at the required throughput. This testing included the complete off site integration of functional components or glove boxes, with the attendant integrated control system and undertaking continuous, non-stop, operational effectiveness proof tests. This paper describes the process, plant and technology used within the AMWTP and provides an outline of the associated design, procurement, fabrication, testing and construction.

Technical Safety Requirements for the B695 Segment of the Decontamination and Waste Treatment Facility  

SciTech Connect (OSTI)

This document contains Technical Safety Requirements (TSRs) for the Radioactive and Hazardous Waste Management (RHWM) Division's B695 Segment of the Decontamination and Waste Treatment Facility (DWTF) at Lawrence Livermore National Laboratory (LLNL). The TSRs constitute requirements regarding the safe operation of the B695 Segment of the DWTF. The TSRs are derived from the Documented Safety Analysis (DSA) for the B695 Segment of the DWTF (LLNL 2004). The analysis presented there determined that the B695 Segment of the DWTF is a low-chemical hazard, Hazard Category 3, nonreactor nuclear facility. The TSRs consist primarily of inventory limits as well as controls to preserve the underlying assumptions in the hazard analyses. Furthermore, appropriate commitments to safety programs are presented in the administrative controls section of the TSRs. The B695 Segment of the DWTF (B695 and the west portion of B696) is a waste treatment and storage facility located in the northeast quadrant of the LLNL main site. The approximate area and boundary of the B695 Segment of the DWTF are shown in the B695 Segment of the DWTF DSA. Activities typically conducted in the B695 Segment of the DWTF include container storage, lab-packing, repacking, overpacking, bulking, sampling, waste transfer, and waste treatment. B695 is used to store and treat radioactive, mixed, and hazardous waste, and it also contains equipment used in conjunction with waste processing operations to treat various liquid and solid wastes. The portion of the building called Building 696 Solid Waste Processing Area (SWPA), also referred to as B696S in this report, is used primarily to manage solid radioactive waste. Operations specific to the SWPA include sorting and segregating low-level waste (LLW) and transuranic (TRU) waste, lab-packing, sampling, and crushing empty drums that previously contained LLW. A permit modification for B696S was submitted to DTSC in January 2004 to store and treat hazardous and mixed waste. Upon approval of the permit modification, B696S rooms 1007, 1008, and 1009 will be able to store hazardous and mixed waste for up to 1 year. Furthermore, an additional drum crusher and a Waste Packaging Unit will be permitted to treat hazardous and mixed waste. RHWM generally processes LLW with no, or extremely low, concentrations of transuranics (i.e., much less than 100 nCi/g). Wastes processed often contain only depleted uranium and beta- and gamma-emitting nuclides, e.g., {sup 90}Sr, {sup 137}Cs, {sup 3}H. Chapter 5 of the DSA documents the derivation of TSRs and develops the operational limits that protect the safety envelope defined for this facility. The DSA is applicable to the handling of radioactive waste stored and treated in the B695 Segment of the DWTF. Section 5 of the TSR, Administrative Controls, contains those Administrative Controls necessary to ensure safe operation of the B695 Segment of the DWTF. A basis explanation follows each of the requirements described in Section 5.5, Specific Administrative Controls. The basis explanation does not constitute an additional requirement, but is intended as an expansion of the logic and reasoning behind development of the requirement. Programmatic Administrative Controls are addressed in Section 5.6.

Economicenvironmental analysis of handling biogas from sewage sludge digesters in \\{WWTPs\\} (wastewater treatment plants) for energy recovery: Case study of Bekkelaget WWTP in Oslo (Norway)  

Science Journals Connector (OSTI)

Abstract This paper outlines a methodology for a systematic economicenvironmental analysis of realistic and realisable options for recovering and utilising energy from biogas produced in sewage sludge digesters in \\{WWTPs\\} (wastewater treatment plants). Heat, electricity and transport fuel can be produced from biogas, consumed in-plant or even sold to external end-users. The paper initially considers global warming as the environmental impact of concern, but later also stresses on the necessity of avoiding problem shifting by factoring in other environmental impact categories as well. The methodology is subsequently applied to the Bekkelaget WWTP in Oslo (Norway). Five different options for handling biogas are considered, in addition to the status quo the business-as-usual in year-2012, and a baseline case, where it is assumed that all biogas generated is flared completely and not utilised for energy recovery of any kind. Seven different cost scenarios for electricity, natural gas, wood pellets, bio-methane and diesel are constructed. This gives a total of 49 combinations, for each of which the net costs and net environmental impacts (global warming, eutrophication and acidification) are determined for the 10-year period 20122021. The changes (in percentages) with respect to the corresponding values for the baseline case, are recorded; suitable weighting factors are considered after interaction with experts and personnel associated with the plant, and the options are evaluated using this double-bottom-line approach (economic and environmental).

Two pilot rinse wastewater reuse projects were developed as part of a long-term water conservation program for a Motorola semiconductor manufacturing site in Phoenix, Ariz. The conceptual designs for the projects grew out of a detailed wastewater reuse study that characterized wastewater streams at their generation points. Both treatment techniques were specifically researched, bench-tested, and adapted to further water conservation efforts while ensuring 100 percent compliance with appropriate effluent regulations and industrial discharge permit conditions. Together, the pilot projects save the city of Phoenix approximately 45 mil gal (17 {times} 10{sup 4} m{sup 3}) of water annually.

The Idaho Cleanup Project has prepared this interim control strategy for the U.S. Department of Energy Idaho Operations Office pursuant to DOE Order 5400.5, Chapter 11.3e (1) to support continued discharges to the Test Area North/Technical Support Facility Sewage Treatment Facility Disposal Pond. In compliance with DOE Order 5400.5, a 2-year review of the Interim Control Strategy document has been completed. This submittal documents the required review of the April 2005 Interim Control Strategy. The Idaho Cleanup Project's recommendation is unchanged from the original recommendation. The Interim Control Strategy evaluates three alternatives: (1) re-route the discharge outlet to an uncontaminated area of the TSF-07; (2) construct a new discharge pond; or (3) no action based on justification for continued use. Evaluation of Alternatives 1 and 2 are based on the estimated cost and implementation timeframe weighed against either alternative's minimal increase in protection of workers, the public, and the environment. Evaluation of Alternative 3, continued use of the TSF-07 Disposal Pond under current effluent controls, is based on an analysis of four points: - Record of Decision controls will protect workers and the public - Risk of increased contamination is low - Discharge water will be eliminated in the foreseeable future - Risk of contamination spread is acceptable. The Idaho Cleanup Project recommends Alternative 3, no action other than continued implementation of existing controls and continued deactivation, decontamination, and dismantlement efforts at the Test Area North/Technical Support Facility.

Uranium-Loaded Water Treatment Resins: 'Equivalent Feed' at NRC and Agreement State-Licensed Uranium Recovery Facilities - 12094  

SciTech Connect (OSTI)

Community Water Systems (CWSs) are required to remove uranium from drinking water to meet EPA standards. Similarly, mining operations are required to remove uranium from their dewatering discharges to meet permitted surface water discharge limits. Ion exchange (IX) is the primary treatment strategy used by these operations, which loads uranium onto resin beads. Presently, uranium-loaded resin from CWSs and mining operations can be disposed as a waste product or processed by NRC- or Agreement State-licensed uranium recovery facilities if that licensed facility has applied for and received permission to process 'alternate feed'. The disposal of uranium-loaded resin is costly and the cost to amend a uranium recovery license to accept alternate feed can be a strong disincentive to commercial uranium recovery facilities. In response to this issue, the NRC issued a Regulatory Issue Summary (RIS) to clarify the agency's policy that uranium-loaded resin from CWSs and mining operations can be processed by NRC- or Agreement State-licensed uranium recovery facilities without the need for an alternate feed license amendment when these resins are essentially the same, chemically and physically, to resins that licensed uranium recovery facilities currently use (i.e., equivalent feed). NRC staff is clarifying its current alternate feed policy to declare IX resins as equivalent feed. This clarification is necessary to alleviate a regulatory and financial burden on facilities that filter uranium using IX resin, such as CWSs and mine dewatering operations. Disposing of those resins in a licensed facility could be 40 to 50 percent of the total operations and maintenance (O and M) cost for a CWS. Allowing uranium recovery facilities to treat these resins without requiring a license amendment lowers O and M costs and captures a valuable natural resource. (authors)

Destruction and formation of PCDD/Fs in a fluidised bed combustor co-incinerating automotive shredder residue with refuse derived fuel and wastewater treatment sludge  

Science Journals Connector (OSTI)

During an eight day trial automotive shredder residue (ASR) was added to the usual waste feed of a Fluidized Bed Combustor (FBC) for waste-to-energy conversion; the input waste mix consisted of 25% ASR, 25% refuse-derived fuel (RDF) and 50% wastewater treatment (WWT) sludge. All inputs and outputs were sampled and the concentration of the 17 PCDD/Fs with TEF-values was determined in order to obtain PCDD/F fingerprints. The ASR contained approximately 9000ng PCDD/Fs/kgDW, six times more than the RDF and 10 times more than the WWT sludge. The fingerprint of ASR and RDF was dominated by HpCDD and OCDD, which accounted for 90% of the total PDDD/F content, whereas the WWT sludge contained relatively more HpCDFs and OCDF (together 70%). The flue gas cleaning residue (FGCR) and fly and boiler ash contained approximately 30,000 and 2500ng PCDD/Fs/kgDW, respectively. The fingerprints of these outputs were also dominated by HpCDFs and OCDF. The bottom ash contained only OCDD and OCDF, in total 8ng PCDD/Fs/kgDW. From the comparison of the bottom ash fingerprints with the fingerprints of the other output fractions and of the inputs, it could be concluded that the PCDD/Fs in the waste were destroyed and new PCDD/Fs were formed in the post combustion process by de novo synthesis. During the ASR-co-incineration, the PCDD/F congener concentrations in the fly and boiler ash, FGCR and flue gas were 1.2510 times higher compared to the same output fractions generated during incineration of the usual waste mix (70% RDF and 30% WWT sludge). The concentration of the higher chlorinated PCDD/Fs increased most. As these congeners have the lowest TEF-factors, the total PCDD/F output, expressed in kg TEQ/year, of the FBC did not increase significantly when ASR was co-incinerated. Due to the relatively high copper levels in the ASR, the copper concentrations in the \\{FBCs\\} outputs increased. As copper catalysis the de novo syntheses, this could explain the increase in PCDD/F concentrations in these outputs.

Hazard Evaluation for Storage of Spent Nuclear Fuel (SNF) Sludge at the Solid Waste Treatment Facility  

SciTech Connect (OSTI)

As part of the Spent Nuclear Fuel (SNF) storage basin clean-up project, sludge that has accumulated in the K Basins due to corrosion of damaged irradiated N Reactor will be loaded into containers and placed in interim storage. The Hanford Site Treatment Complex (T Plant) has been identified as the location where the sludge will be stored until final disposition of the material occurs. Long term storage of sludge from the K Basin fuel storage facilities requires identification and analysis of potential accidents involving sludge storage in T Plant. This report is prepared as the initial step in the safety assurance process described in DOE Order 5480.23, Nuclear Safety Analysis Reports and HNF-PRO-704, Hazards and Accident Analysis Process. This report documents the evaluation of potential hazards and off-normal events associated with sludge storage activities. This information will be used in subsequent safety analyses, design, and operations procedure development to ensure safe storage. The hazards evaluation for the storage of SNF sludge in T-Plant used the Hazards and Operability Analysis (HazOp) method. The hazard evaluation identified 42 potential hazardous conditions. No hazardous conditions involving hazardous/toxic chemical concerns were identified. Of the 42 items identified in the HazOp study, eight were determined to have potential for onsite worker consequences. No items with potential offsite consequences were identified in the HazOp study. Hazardous conditions with potential onsite worker or offsite consequences are candidates for quantitative consequence analysis. The hazardous conditions with potential onsite worker consequences were grouped into two event categories, Container failure due to overpressure - internal to T Plant, and Spill of multiple containers. The two event categories will be developed into accident scenarios that will be quantitatively analyzed to determine release consequences. A third category, Container failure due to overpressure--external to T Plant, was included for completeness but is not within the scope of the hazards evaluation. Container failures external to T Plant will be addressed as part of the transportation analysis. This document describes the HazOp analysis performed for the activities associated with the storage of SNF sludge in the T Plant.

Low-level liquid radioactive waste treatment at Murmansk, Russia: Technical design and review of facility upgrade and expansion  

SciTech Connect (OSTI)

The governments of Norway and the US have committed their mutual cooperation and support the Murmansk Shipping Company (MSCo) to expand and upgrade the Low-Level Liquid Radioactive Waste (LLRW) treatment system located at the facilities of the Russian company RTP Atomflot, in Murmansk, Russia. RTP Atomflot provides support services to the Russian icebreaker fleet operated by the MSCo. The objective is to enable Russia to permanently cease disposing of this waste in Arctic waters. The proposed modifications will increase the facility`s capacity from 1,200 m{sup 3} per year to 5,000 m{sup 3} per year, will permit the facility to process high-salt wastes from the Russian Navy`s Northern fleet, and will improve the stabilization and interim storage of the processed wastes. The three countries set up a cooperative review of the evolving design information, conducted by a joint US and Norwegian technical team from April through December, 1995. To ensure that US and Norwegian funds produce a final facility which will meet the objectives, this report documents the design as described by Atomflot and the Russian business organization, ASPECT, both in design documents and orally. During the detailed review process, many questions were generated, and many design details developed which are outlined here. The design is based on the adsorption of radionuclides on selected inorganic resins, and desalination and concentration using electromembranes. The US/Norwegian technical team reviewed the available information and recommended that the construction commence; they also recommended that a monitoring program for facility performance be instituted.

Delisting petition for 300-M saltstone (treated F006 sludge) from the 300-M liquid effluent treatment facility  

SciTech Connect (OSTI)

This petition seeks exclusion for stabilized and solidified sludge material generated by treatment of wastewater from the 300-M aluminum forming and metal finishing processes. The waste contains both hazardous and radioactive components and is classified as a mixed waste. The objective of this petition is to demonstrate that the stabilized sludge material (saltstone), when properly disposed, will not exceed the health-based standards for the hazardous constituents. This petition contains sampling and analytical data which justify the request for exclusion. The results show that when the data are applied to the EPA Vertical and Horizontal Spread (VHS) Model, health-based standards for all hazardous waste constituents will not be exceeded during worst case operating and environmental conditions. Disposal of the stabilized sludge material in concrete vaults will meet the requirements pertaining to Waste Management Activities for Groundwater Protection at the Savannah River Site in Aiken, S.C. Documents set forth performance objectives and disposal options for low-level radioactive waste disposal. Concrete vaults specified for disposal of 300-M saltstone (treated F006 sludge) assure that these performance objectives will be met.

Treatment of Uranium and Plutonium Solutions Generated in the Atalante Facility, France - 12004  

SciTech Connect (OSTI)

The Atalante complex operated by the French Alternative Energies and Atomic Energy Commission (CEA) at the Rhone Valley Research Center consolidates research programs on actinide chemistry, especially separation chemistry, processing for recycling spent fuel, and fabrication of actinide targets for innovative concepts in future nuclear systems. The design of future systems (Generation IV reactors, material recycling) will increase the uranium and plutonium flows in the facility, making it important to anticipate the stepped-up activity and provide Atalante with equipment dedicated to processing these solutions to obtain a mixed uranium-plutonium oxide that will be stored pending reuse. Ongoing studies for integral recycling of the actinides have highlighted the need for reserving equipment to produce actinides mixed oxide powder and also minor actinides bearing oxide for R and D purpose. To meet this double objective a new shielded line should be built in the facility and should be operational 6 years after go decision. The main functions of the new unit would be to receive, concentrate and store solutions, purify them, ensure group conversion of actinides and conversion of excess uranium. This new unit will be constructed in a completely refurbished building devoted to subcritical and safe geometry of the process equipments. (author)

Contribution of floor treatment characteristics to background noise levels in health care facilities, Part 1  

Science Journals Connector (OSTI)

Acoustical tests were conducted on five types of commercial-grade flooring to assess their potential contribution to noise generated within health care facilities outside of patient rooms. The floor types include sheet vinyl (with and without a 5 mm rubber backing) virgin rubber (with and without a 5 mm rubber backing) and a rubber-backed commercial grade carpet for comparison. The types of acoustical tests conducted were ISO-3741 compliant sound power level testing (using two source types: a tapping machine to simulate footfalls and a rolling hospital cart) and sound absorption testing as per ASTM-C423. Among the non-carpet samples the material type that produced the least sound power was determined to be the rubber-backed sheet vinyl. While both 5 mm-backed samples showed a significant difference compared to their un-backed counterparts with both source types the rubber-backed sheet vinyl performed slightly better than the rubber-backed virgin rubber in the higher frequency bands in both tests. The performance and suitability of these flooring materials in a health care facility compared to commercial carpeting will be discussed. [Work supported by Paul S. Veneklasen Research Foundation.

Wastewater heat recovery apparatus  

DOE Patents [OSTI]

A heat recovery system is described with a heat exchanger and a mixing valve. A drain trap includes a heat exchanger with an inner coiled tube, baffle plate, wastewater inlet, wastewater outlet, cold water inlet, and preheated water outlet. Wastewater enters the drain trap through the wastewater inlet, is slowed and spread by the baffle plate, and passes downward to the wastewater outlet. Cold water enters the inner tube through the cold water inlet and flows generally upward, taking on heat from the wastewater. This preheated water is fed to the mixing valve, which includes a flexible yoke to which are attached an adjustable steel rod, two stationary zinc rods, and a pivoting arm. The free end of the arm forms a pad which rests against a valve seat. The rods and pivoting arm expand or contract as the temperature of the incoming preheated water changes. The zinc rods expand more than the steel rod, flexing the yoke and rotating the pivoting arm. The pad moves towards the valve seat as the temperature of the preheated water rises, and away as the temperature falls, admitting a variable amount of hot water to maintain a nearly constant average process water temperature. 6 figs.

Valuation of a Municipal Wastewater Plant Expansion: An Application to a High Growth Resort Area in Canada  

E-Print Network [OSTI]

The municipal water and wastewater sector is considered to be the most capital intensive industrial sector. Naturally, any methodology that has the potential to improve capital allocation decision making, has the potential to make a positive financial contribution to this sector. Most managers are aware of the power of calculating the Net Present Value (NPV) of an investment decision using Discounted Cash Flows (DCF). The problem with DCF based NPV analysis is that the inherent value of future project options is not modeled. In this study, we consider a small resort-based municipality faced the question of how big to make their new wastewater treatment facility to meet the expanding demand of 10 % growth in the number of new residential connections to the wastewater treatment infrastructure. Since a significant number of new dwellings are second weekend homes, the planners felt strongly that growth rates were tied to the strength of the market index. Here we set the model framework for considering optimal plant size based on correlation assumptions of municipal growth to the market index. The model takes on the form of an Asian option. The results show that the greater the (assumed) correlation, the smaller the required plant size. Penalty costs associated with not building a large enough plant are hedged in the market. This paper sets that basis for future analysis of staged plant expansion analysis.

1990 Washington State directory of biomass energy facilities  

SciTech Connect (OSTI)

This second edition is an update of biomass energy production and use in Washington State for 1989. The purpose of this directory is to provide a listing of known biomass users within the state and some basic information about their facilities. The data can be helpful to persons or organizations considering the use of biomass fuels. The directory is divided into three sections of biomass facilities with each section containing a map of locations and a data summary table. In addition, a conversion table, a glossary and an index are provided in the back of the directory. The first section deals with biogas production from wastewater treatment plants. The second section provides information on the wood combustion facilities in the state. This section is subdivided into two categories. The first is for facilities connected with the forest products industries. The second category include other facilities using wood for energy. The third section is composed of three different types of biomass facilities -- ethanol, municipal solid waste, and solid fuel processing. Biomass facilities included in this directory produce over 64 trillion Btu (British thermal units) per year. Wood combustion facilities account for 91 percent of the total. Biogas and ethanol facilities each produce close to 800 billion Btu per year, MSW facilities produce 1845 billion BTU, and solid fuel processing facilities produce 2321 billion Btu per year. To put these numbers in perspective, Washington's industrial section uses 200 trillion Btu of fuels per year. Therefore, biomass fuels used and/or produced by facilities listed in this directory account for nearly 32 percent of the state's total industrial fuel demand. This is a sizable contribution to the state's energy needs.

Review on electrical discharge plasma technology for wastewater remediation  

Science Journals Connector (OSTI)

Abstract As wastewater remediation becomes a global concern, the development of innovative advanced oxidation processes for wastewater treatment is still a major challenge. With regard to its fast removal rate and environmental compatibility, plasma technology is considered as a promising remediation technology for water remediation. The principles of electrical plasma with liquids for pollutant removal and the reactors of various electrical discharge types are outlined in this review. To improve energy efficiency, combination of plasma technology with catalysts has attracted significant attention. The present review is concerned about present understanding of the mechanisms involved in these combined processes. Further on, detailed discussions are given of the effects of various factors on the performance of pulsed electrical plasma technology in water treatment processes. Finally, special attention is paid to the future challenges of plasma technology utilized for industrial wastewater treatment.

Water balance analysis and wastewater recycling investigation in electrolytic manganese industry of China A case study  

Science Journals Connector (OSTI)

Abstract A water balance investigation was performed for a representative electrolytic manganese metal (EMM) enterprise to study the details of water consumption and generation in the production process. A new integrated wastewater treatment approach was put forward to recover useful chemicals from the process wastewater, which contained high concentrations of Mn2+, Cr(VI), Cr3+, and NH4+. Cr(VI) was recovered from the wastewater by ion exchange techniques and reused as EMM passivant. The remaining wastewater containing Mn2+ and NH4+ was returned to the leaching section before the impurity removal procedure to prepare electrolytes. Complete wastewater recycling was achieved after water balance regulation and optimization. Final demonstration line results proved that the proposed process is feasible and exhibits significant advantages of better treatment effects, lower costs and lower environmental impact compared to the traditional reductionneutralizationsedimentation treatment method. With the adoption of the proposed approach, solid waste disposal cost and the required area for the landfill yard were decreased by 80%. Operating costs for wastewater treatment were lowered by 85%. Around 4.8kg/t EMM of Mn2+, 5.2kg/t EMM of NH4+ and 0.24kg/t EMM of Cr(VI) were recovered. The recycled wastewater proportion was increased from 6.2% to 100.0%. 1.168m3/t EMM of fresh water was saved and the equivalent amount of discharging wastewater was reduced to the environment.

Final closure plan for the high-explosives open burn treatment facility at Lawrence Livermore National Laboratory Experimental Test Site 300  

SciTech Connect (OSTI)

This document addresses the interim status closure of the HE Open Bum Treatment Facility, as detailed by Title 22, Division 4.5, Chapter 15, Article 7 of the Califonia Code of Regulations (CCR) and by Title 40, Code of Federal Regulations (CFR) Part 265, Subpart G, ``Closure and Post Closure.`` The Closure Plan (Chapter 1) and the Post- Closure Plan (Chapter 2) address the concept of long-term hazard elimination. The Closure Plan provides for capping and grading the HE Open Bum Treatment Facility and revegetating the immediate area in accordance with applicable requirements. The Closure Plan also reflects careful consideration of site location and topography, geologic and hydrologic factors, climate, cover characteristics, type and amount of wastes, and the potential for contaminant migration. The Post-Closure Plan is designed to allow LLNL to monitor the movement, if any, of pollutants from the treatment area. In addition, quarterly inspections will ensure that all surfaces of the closed facility, including the cover and diversion ditches, remain in good repair, thus precluding the potential for contaminant migration.

Wastewater minimization in industrial applications: Challenges and solutions  

SciTech Connect (OSTI)

The impetus for waste minimization and water recycle in the metal processing industry comes from increasingly stringent environmental regulations and dwindling water supplies. Tougher discharge permits often dictate additional wastewater treatments, which can make water recycle and waste minimization an attractive option. The most challenging part in the design of a water recycle system is to minimize the capital and operating costs while meeting the water quality requirements of the process. Computer simulation of water recycle alternatives provides: (1) ``expected`` water chemistry, (2) steady-state mass and energy balance for the plant water system, (3) performance of the water treatments considered in the water recycle scheme, and (4) relative economics based on capital and operating costs. The computer simulation study recommends the best wastewater recycle scheme based on economics and technical merits. Benefits of a computer simulation study in the design of water recycle and wastewater minimization processes are illustrated by a case study in the metal processing industry.
