| Abstract | With the reauthorization of the Resource Conservation and Recovery Act (RCRA) and the concurrent restrictions on land disposal of hazardous wastes, the U.S. Environmental Protection Agency is assessing technologies that can be substituted for, or precursors to land disposal. The paper describes the research work being conducted at the EPA's Test and Evaluation Facility concerning treatment of metal finishing hazardous wastewater. A series of various technological units have been designed and fabricated to determine the optimum combination of the units for the best treatment of any given wastes. These units are: Alkaline Chlorination of Cyanide, Chromium Reduction, Neutralization/Precipitation, Flocculation and Settling, Mixed-Media Filtration, Activated Carbon Adsorption, and Ion Exchange. Plans for future work utilizing additional technological units will also be presented. Results of this work will be used to assess alternative treatment technologies for aqueous metal and cyanide beariig hazardous wastes. |
