Abstract
The volume, a collection of 10 research papers originating at the Robert A. Taft Sanitary Engineering Center, describes the effects of chromium, copper, nickel, and zinc on sewage treatment processes. Results of pilot plant studies and full-scale municipal plants are given. For each of the metals and combinations of metals studied, the effects on the aerobic and anaerobic treatment processes, under continuous dosage, are given. The data presented allow a reasonable estimate to be made of the amount of metallic wastes that a treatment plant can receive and accomplish the desired efficiency of treatment. The effects of slug discharges of the metals on the aerobic and anaerobic processes under pilot plant conditions and at municipal plants are presented. The concentrations of the metals in the various sludges and effluents produced by a treatment plant are given. Metal balances conducted for each of the studies show the amount of metal removed by primary and secondary treatment. (Author)
