Description:
The Northern Regional Research Center developed an effective process to remove heavy metals from wastewaters of two nonferrous metal industries and insoluble starch xanthate (ISX). The study included bench-scale evaluation of wastewaters from two lead battery and one brass mill waste. The evaluation included: (1) Determination of the metals and concentrations in the raw and treated wastewaters; (2) treatment with ISX alone and in combination with selected coagulant aids; (3) recovery of heavy metals from ISX sludge; and (4) determination of the potential reuse of the treated effluent. Several other effective and economical treatment processes were also developed for specific waste streams from printed circuit manufacturers. Based on the evaluation of results in this study, recommendations were made as to the desirability of constructing a prototype plant for actual on-site testing in selected industries. This report contains an extensive bibliography of references dealing with these industries.
