Chemical Waste Management, Inc. PO*WW*ER (Trade Name) Evaporation-Catalytic Oxidation Technology. Technology Evaluation Report. Volume 1

摘要

As part of the Superfund Innovative Technology Evaluation (SITE) Program, the U.S. Environmental Protection Agency (EPA) demonstrated the Chemical Waste Management, Inc. (CWM), PO*WW*ER(tm) technology. The SITE demonstration was conducted in September 1992 at CWM's Lake Charles Treatment Center (LCTC) site in Lake Charles, Louisiana. During the demonstration, the PO*WW*ER(tm) system treated landfill leachate contaminated with volatile organic compounds (VOC), semivolatile organic compounds (SVOC), metals, ammonia, cyanide, and other inorganic contaminants. SITE demonstration results show that during treatment in the PO*WW*ER(tm) system, the volume of the landfill leachate was significantly reduced. A total solids (TS) concentration ratio of 32 to 1 was achieved. The SITE demonstration results also show that the PO*WW*ER(tm) system effectively removed sources of toxicity such as VOCs, SVOCs, metals, ammonia, and cyanide. Concentrations of VOCs and SVOCs in product condensate exiting the PO*WW*ER(tm) system were below their respective detection limits of 5 to 10 micrograms per liter (micrograms/L) and 10 to 130 micrograms/L.
