Treatment of aqueous metal-bearing hazardous wastes
The paper describes the work being conducted at USEPA's Test and Evaluation Facility involving the treatment of metal-finishing hazardous wastewaters. This work is part of a comprehensive program supporting the demonstration, testing, and evaluation of treatment process that have the potential to be utilized to meet the forthcoming requirements of the land-disposal restriction of the HSWA, 1984. A variety of unit-treatment processes have been fabricated to offer BDAT (Best Demonstrated Available Technology) in treating hazardous, aqueous-metal-waste streams. These unit processes include lime precipitation, flocculation, clarification, sulfide precipitation, mixed-media filtration, ion exchange, and granular activated-carbon adsorption. The results of the first three test runs are presented.
