CWM PO * WW * ERTM Evaporation - Catalytic Oxidation Technology Applications

Notice The information in this document has been prepared for the U.S. Environmental Protection Agency (EPA) Superfund Innovative Technology Evaluation (SITE) programunder Contract No. 6% CO-0047. This document has been subjected to EPA peer and administrative reviews and has been approved for publication as an EPA document. Mention of trade names or commercial products does not constitute an endorsement or recommendation for use. Foreword The Superfund Innovative Technology Evaluation (SITE) program was authorized by the 1986 Superfund Amendments and Reauthorization Act (SARA). The SITE program is a joint effort between the EPA Office of Research and Development (ORD) and the Office of Solid Waste and Emergency.Response (OSWER). The purpose of the program is to accelerate the development and use of innovative cleanup technologies applicable to Superfund and other hazardous waste sites through field technology demonstrations designed to provide performance and cost data on selected technologies. A field demonstration was conducted under the SITE program to evaluate the Chemical Waste Management, Inc. (CWM), PO*WW*ERTM technology. The technology demonstration took place at CWM's Lake Charles Treatment Center (LCTC) site in Lake Charles, Louisiana. The purpose of the demonstration effort was to obtain information on the performance and cost of the technology and to assess its use at this and other uncontrolled hazardous waste sites. Documentation of the demonstration consists of two reports: (1) a Technology Evaluation Report, which describes field activities and laboratory results; and (2) this Applications Analysis Report, which interprets the demonstration data and discusses the technology's potential applicability. Abstract This report evaluates the Chemical Waste Management, Inc. (CWM), PO*WW*ERTM technology's ability to remove volatile organic compounds (VOC), semivolatile organic compounds (SVOC), ammonia, cyanide, metals, and other inorganic contaminants from aqueous wastes. This evaluation is based on treatment performance and cost data obtained from the Super-fund Innovative Technology Evaluation (SITE) demonstration and 11 case studies conducted by CWM. The PO*WW*ERTM system reduces the volume of an aqueous waste and catalytically oxidizes volatile contaminants. The PO*WW*ERTM system consists primarily of (1) an evaporator that reduces influent wastewater volume, (2) a catalytic oxidizer that oxidizes the volatile contaminants in the vapor stream from the evaporator, (3) a scrubber that removes acid gases formed during oxidation, and (4) a condenser that condenses the vapor stream leaving the scrubber. landfill leachate, an F039 hazardous waste, contaminated with VOCs, SVOCs, ammonia, cyanide, metals, and other inorganic contaminants. During the development of the PO*WW*ERTM system, CWM …
