| Abstract | This project assessed the variables influencing the removal of eight metals through combined industrial-municipal treatment plants. The eight metals investigated were: aluminum, cadmium, chromium, copper, iron, lead, nickel, and zinc. The metals were studied at subtoxic influent concentrations, and the interrelationships which influence metal removal were assessed. Batch studies on raw sewage and activated sludge identified and defined the impact of individual parameters or concentrations and of combinations of parameters on metals removal. Eight pilot treatment plants, each consisting of primary clarifier, aeration basin, and secondary clarifier, were operated at varying influent metal levels to study the effect of significant variables indicated from the batch studies. The results of this project indicate that the removal of metals in combined industrial-municipal treatment systems is influenced by a number of wastewater and treatment plant operation characteristics. |
