    The EPA is promulgating National Emission Standards for Hazardous Air Pollutants for Polyvinyl Chloride and Copolymers Production. The final rules establish emission standards that apply at all times, including periods of startup, shutdown and malfunction, for hazardous air pollutants from. Removal of organic compounds in wastewater is a very important subject of research in the field of environmental chemistry. In this sense, photocatalysis is a handy promising technology, very attractive for wastewater treatment and water potabilization (Nikolaki et al., ; Lim et al., ).

    Of this wastewater, ammonia has been identified as the major pollutant and can be removed by such treatment methods as air stripping, nitrification-denitrification, partial nitrification-anammox, and membrane distillation, but there are no value-added products. Zero liquid discharge (ZLD)—a wastewater management strategy that eliminates liquid waste and maximizes water usage efficiency — has attracted renewed interest worldwide in recent years. Although implementation of ZLD reduces water pollution and augments water supply, the technology is constrained by high cost and intensive energy by:

EPA/// September BENCH-SCALE EVALUATION OF AMMONIA REMOVAL FROM WASTEWATER BY STEAM STRIPPING by G.B. Wickramanayake (Work Assignment Leader) D. Evers, J.A. Kittel, and A. Gavaskar BATTELLE Columbus Division Columbus, Ohio EPA Contract No. Project Officer J. Ammonia stripping works well with wastewater that has ammonia contents between 10 to mg/l.

For higher ammonia content (more than mg/l), it may be more economical to use alternate ammonia removal techniques, such as steam stripping or biological methods. Air stripping may also be used to remove many hydrophobic organic. ammonia removal from synthetical ly compounded wastewater samples using a bench-scale steam stripping apparatus to support t he development of wastewater discharge standar ds for ammonia in.

Some of the alternative methods for treatment and disposal of shale oil retort water are reviewed: land treatment and disposal, underground injection, suspended solids removal, steam stripping, biological treatment, adsorption of organics.

Effluents from various treatment steps in the bench-scale studies were analyzed for heavy metals and boron. @article{osti_, title = {Laboratory tests of phenol removal and ammonia and hydrogen sulfide stripping from SRC-I wastewater.

Abstract The Tennessee Valley Authority has been monitoring Author: Tien-Yung J. Chu, Peter A. Krenkel, Richard J. Ruane. Since the late s, a series of process concepts based largely on aqueous phase hydroxyl radical chemistry have been demonstrated to completely destroy (mineralize), under appropriate conditions, a wide spectrum of organic, haloorganic, and metallo-organic compounds found as dilute contaminants of well water, aquifers, and surface waters or as components of industrial and domestic wastewater.
