Title: Investigation of the decolorization efficiency of two pin-to-plate corona discharge plasma system for industrial wastewater treatment

Abstract

In this article, a dual pin-to-plate high-voltage corona discharge system is introduced to study experimentally the gap distance, the contact time, the effect of pin and plate materials, the thickness of ground plate and the conductivity on the amount of Acid Blue 25 dye color removal efficiency from polluted water. A study for the optimum air gap distance between dual pin and surface of Acid Blue 25 dye solution is carried out using 3D-EM simulator to find maximum electric field intensity at the tip of both pins. The outcomes display that the best gap for corona discharge is approximately 5 mm for 15-kV source. This separation is constant during the study of other factors. In addition, an investigation of the essential reactive species responsible for oxidation of the dye organic compounds (O{sub 3} in air discharge, O{sub 3} in water, and H{sub 2}O{sub 2}) during the experimental time is conducted. Three various materials such as: stainless steel, copper and aluminum are used for pins and plate. The maximum color removal efficiencies of Acid Blue 25 dyes are 99.03, 82.04, and 90.78% after treatment time 15 min for stainless steel, copper, and aluminum, respectively. Measurement results for the impact of thicknessmore » of an aluminum ground plate on color removal competence show color removal efficiencies of 86.3, 90.78, and 98.06% after treatment time 15 min for thicknesses of 2, 0.5, and 0.1 mm, respectively. The increasing of the solution conductivity leads to the reduction of decolorization efficiency. A kinetic model is used to define the performance of corona discharge system. The models of pseudo-zero-order, pseudo-first-order, and pseudo-second-order reaction kinetics are utilized to investigate the decolorization of Acid Blue 25 dye. The rate of degradation of Acid Blue 25 dye follows the pseudo-first-order kinetics in the dye concentration.« less

  • The promulgation of increasingly stringent effluent guidelines and penalties for permit violations has dictated the need for reliable and cost-effective industrial wastewater treatment systems. This paper presents a case study that compares industrial wastewater treatment system requirements for indirect and direct discharge options. The results are based on a five-month bench-scale study that compared biological treatment and activated carbon treatment for removal of priority pollutants from a complex organic chemicals wastewater. Alternative discharge limits were defined by the OCPSF categorical limits, local POTW requirements and state water quality standards. The results of this study indicated that suspended solids removal followedmore » by granular activated carbon (GAC) columns was the most cost-effective pretreatment system.« less
  • Laboratory tests were conducted for removal of SO{sub 2} from simulated flue gas and simultaneous treatment of wastewater from blast furnace by pulsed corona discharge. Tests were conducted for the flue gas flow from 12 to 18 Nm{sup 3}/h, the simulated gas temperature from 80 to 120 {sup o}C, the inlet flux of wastewater from 33 to 57 L/h, applied voltage from 0 to 27 kV, and SO{sub 2} initial concentration was about 1,430 mg/m{sup 3}. Results showed that wastewater from blast furnace has an excellent ability of desulphurization (about 90%) and pulsed corona discharge can enhance the desulphurization efficiency.more » Meanwhile, it was observed that the SO{sub 2} removal ratio decreased along with increased cycle index, while it increased as the flux of flue gas was reduced, and increased when the flux of wastewater from blast furnace was increased. In addition, results demonstrated that the content of sulfate radical produced in wastewater increase with an increment of applied pulsed voltage, cycle index, or the flux of flue gas. Furthermore, the results indicated that the higher the inlet content of cyanide the better removal effect of it, and the removal rate can reach 99.9% with a residence time of 2.1 s in the pulsed corona zone during the desulphurization process when the inlet content was higher, whereas there was almost no removal effect when the inlet content was lower. This research may attain the objective of waste control, and can provide a new way to remove SO{sub 2} from flue gas and simultaneously degrade wastewater from blast furnace for integrated steel plants.« less
  • The effects of additional gas composition on the corona discharge characteristics in a pipe with nozzle electrode system and the NO[sub x] removal characteristics for flue gases are experimentally investigated. The additional gas consists of a mixture of Na + O[sub 2] + NH[sub 3] and a small amount of Ar or CO[sub 2], and is introduced to the flue gas stream from the pipe electrode through the corona discharging zone at the tip of nozzles. The results show that corona discharge characteristics and modes are significantly influenced by the composition of the additional gas mixture. Both NO[sub x] reductionmore » rate and energy yield of NO[sub x] removal increase with decreasing corona discharge input power. NO reduction rate and energy yield can be optimized by the type of the additional gas mixture and the flow rates.« less
  • Under a constant decree agreement in 1988, LTV Steel Co. installed an activated sludge biological treatment facility at the Warren works to treat coke plant wastewater prior to discharge to the city of Warren publicly owned treatment works. This discharge is required to meet effluent quality limits for phenol and ammonia, and suspended solids are subject to surcharges. the discharge limits imposed by the city of Warren are shown in Table 1. To meet these effluent discharge limits, the original treatment strategy was to process the coke plant wastewater through an ammonia steam stripping still to control ammonia, and processmore » the ammonia-stripped wastewater through the activated sludge biological treatment unit to control phenol. This strategy was unsuccessful because of limitations of the ammonia still, the general composition of the wastewater and the operating conditions of the biological treatment process. This article discusses the upgrading of the biological treatment process operation to meet the required discharge effluent quality.« less
  • The development of a corona discharge was evaluated numerically over a finite region of a semi-infinite flat plate having small (ohmic) surface conductivity with flowing gas. The model simulates a positive ion corona discharge (ionic wind) in the direction of gas flow generated by two parallel wires mounted flush with the surface of the plate. The deposition and removal of ions at the surface are permitted. Five coupled partial differential equations govern the gas phase model together with empirical equations for electrical discharge ({Phi}-I characteristic). Two voltage bias case studies were considered: first, the two electrodes have the same potentialmore » but are of opposite sign; and second, the positive electrode carries the full potential with the remaining electrode grounded. Several interesting effects are noted relating to the voltage and current distribution, surface potential, and free-stream velocity. Boundary layer development and surface shear are also discussed.« less
