ABSTRACT
Many industries are being faced with the need to improve the waste management procedures, specifically when hazardous and toxic wastes (HTW) are involved. The ultimate incentive for an industry is the development and application of a comprehensive management strategy that complies with environmental regulatory requirements, maintains or improves product quality and reduces overall costs. This chapter presents a study to investigate the impact of the proposed materials changes on the removal of heavy metals, primarily copper and zinc, from wire mill wastewaters. Observed trends under a variety of test conditions were used to predict any difficulties in meeting federal discharge requirements. The impact of co-precipitation of the metals with residual chromium and its effect on full scale treatment of process wastewaters were examined. Effects on the volumes of process wastes generated and associated cost factors were also considered.
