Title: Treatability study for removal of leachable mercury in crushed fluorescent lamps

Abstract

Nonserviceable fluorescent lamps removed from radiological control areas at the Oak Ridge Department of Energy facilities have been crushed and are currently managed as mixed waste (hazardous and radiologically contaminated). We present proposed treatment flowsheets and supporting treatability study data for conditioning this solid waste residue so that it can qualify for disposal in a sanitary landfill. Mercury in spent fluorescent lamps occurs primarily as condensate on high-surface-area phosphor material. It can be solubilized with excess oxidants (e.g., hypochlorite solution) and stabilized by complexation with halide ions. Soluble mercury in dechlorinated saline solution is effectively removed by cementation with zero-valent iron in the form of steel wool. In packed column dynamic flow testing, soluble mercury was reduced to mercury metal and insoluble calomel, loading > 1.2 g of mercury per grain of steel wool before an appreciable breakthrough of soluble mercury in the effluent.

    Under its ``Green Lights`` program, the US EPA has encouraged companies to replace existing lighting fixtures with newer, more energy-efficient bulbs. A potential impediment to increased use of such energy-efficient bulbs, however, is the cost and regulations associated with disposal of the existing bulbs that would be replaced under Green Lights and similar programs. To better evaluate whether such regulations are necessary, the US EPA issued proposed regulations for disposal of mercury-containing lamps and requested information on the potential for mercury to be released to the atmosphere and to the groundwater. This project included an experiment to measure mercury vapormore » emissions from broken mercury-containing fluorescent lightbulbs and modeling to estimate the potential for impacts on air and groundwater from the disposal of such bulbs at municipal landfills. The flux rates from the experiment were then used to estimate the ambient air concentrations at a landfill. The computed air concentrations at the breathing zone were all low, considerably less than the OSHA limit of 50 {mu}g/m{sup 3}. The predicted air concentrations are still less than 20 {mu}g/m{sup 3} when landfill gas generation is considered, which potentially increases the flux of gases to the surface. Measurements of mercury at actual landfills in the literature also showed low concentrations, and thus are consistent with the above results. Groundwater modeling was also conducted using MYGRT, a two-dimensional solute transport model developed by Tetra Tech for EPRI, to estimate the effect of mercury leaching from bulbs.« less

    The effects of utilizing mercury enriched in /sup 196/Hg on fluorescent lamp efficacy and operational characteristics and results of enrichment of /sup 196/Hg via a photochemical reaction technique are summarized. The central theme of the lamp studies is the measurement of lumen efficacy and electrical operating points as a function of isotopic distribution within individual lamps. That is, test lamps are first run in natural mercury, then mercury containing /sup 196/Hg is dispensed within the lamp. A comparison of the lamp operation before and after /sup 196/Hg dispensing is made to find the effects of altered isotopic distribution on lampmore » operation. Two additional topics were briefly looked into, as indicated; effects of dc magnetic fields applied transverse to the lamp current flow and effects of high frequency lamp operation.« less

The studies are divided into the following four areas: Magnetic Field Effects, Lamp Isotope Experiments, Modeling of Isotope Effects, and ZWHg Isotope Separation in a Flow Reactor.

  • Over the past ten years the Department of Energy Y-12 Site`s Reduction of Mercury in Plant Effluents (RMPE) project has carried out an aggressive investigative program of identifying sources of mercury which are influencing the levels of mercury in Upper East Fork Popular Creek (UEFPC) and exiting the site at Station 17. The driver for these activities has been and continues to be the site`s National Pollution Discharge Elimination Permit (NPDES). This permit establishes certain remedial actions, the schedule for these actions and requires that the mercury in the creek be equal to or less than 5 grams per daymore » by December 31, 1998 and the concentration in the creek be equal to or less than 0.12 {mu} grams per liter on the last day of the permit, April 27, 2000.« less

    As a result of past operations, the Department of Energy’s (DOE) Oak Ridge Y-12 National Security Complex (Y-12 Plant) has extensive mercury-contamination in building structures, soils, storm sewer sediments, and stream sediments, which are a source of pollution to the local ecosystem. Because of mercury’s toxicity and potential impacts on human health and the environment, DOE continues to investigate and implement projects to support the remediation of the Y-12 site.URS and #9122;CH2M Oak Ridge LLC (UCOR) under its prime contract with DOE has cleanup responsibilities on the DOE Oak Ridge Reservation and is investigating potential mercury-contaminated soil treatment technologies throughmore » an agreement with Babcock and Wilcox (B and W) Y-12, the Y-12 operating contractor to DOE. As part of its investigations, UCOR has subcontracted with Brookhaven National Laboratory (BNL) to conduct laboratory-scale studies evaluating the applicability of the Sulfur Polymer Stabilization/Solidification (SPSS) process using surrogate and actual mixed waste Y-12 soils containing mercury (Hg) at 135, 2,000, and 10,000 ppm.SPSS uses a thermoplastic sulfur binder to convert Hg to stable mercury sulfide (HgS) and solidifies the chemically stable product in a monolithic solid final waste form to reduce dispersion and permeability. Formulations containing 40 – 60 dry wt% Y-12 soil were fabricated and samples were prepared in triplicate for Environmental Protection Agency Toxicity Characteristic Leaching Procedure (TCLP) testing by an independent laboratory. Those containing 50 and 60 wt% soil easily met the study criteria for maximum allowable Hg concentrations (47 and 1 ppb, respectively compared with the TCLP limit of 200 ppb Hg). The lowest waste loading of 40 wt% yielded TCLP Hg concentrations slightly higher (240 ppb) than the allowable limit. Since the Y-12 soil tended to form clumps, the improved leaching at higher waste loadings was probably due to reduction in particle size from friction of the soil mixing, which creates more surface area for chemical conversion. This was corroborated by the fact that the same waste loading pre-treated by ball milling to reduce particle size prior to SPSS processing yielded TCLP concentrations almost 30 times lower, and at 8.5 ppb Hg was well below EPA limits. Pre-treatment by ball milling also allowed a reduction in the time required for stabilization, thus potentially reducing total process times by 30%.Additional performance testing was conducted including measurement of compressive strength to confirm mechanical integrity and immersion testing to determine the potential impacts of storage or disposal under saturated conditions. For both surrogate and actual Y-12 treated soils, waste form compressive strengths ranged between 2,300 and 6,500 psi, indicating very strong mechanical integrity (a minimum of greater than 40 times greater than the NRC guidance for low-level radioactive waste). In general, compressive strength increases with waste loading as the soil acts as an aggregate in the sulfur concrete waste forms. No statistically significant loss in strength was recorded for the 30 and 40 wt% surrogate waste samples and only a minor reduction in strength was measured for the 43 wt% waste forms. The 30 wt% Y-12 soil did not show a significant loss in strength but the 50 wt% samples were severely degraded in immersion due to swelling of the clay soil. The impact on Hg leaching, if any, was not determined.« less
