| Abstract |
Laboratory and full-scale studies were conducted at the Hollywood, Florida, sewage treatment plant to determine the efficiency of chemical coagulation for treatment of raw sewage and aerobic digestion of primary sewage sludge. While various polyelectrolytes produced high treatment efficiencies in the laboratory, these efficiencies could not be achieved in full-scale tests due to inadequate mixing and higher soluble BOD concentrations. Sludges were successfully digested aerobically with as little as ten days detention. An oxygen uptake rate of up to 1.8 gm O2/(gm T.S.)(hr) was observed for sludge ages greater than 20 days. The recommended detention time of 20 days produced a solids content between 4 and 6 percent. |
