| Abstract |
This report documents the results of a project initiated to evaluate the handling and disposal of combined sewer overflow (CSO) treatment residuals. Bench scale thickening and pilot and full-scale centrifugation dewatering tests were performed at dry-weather and CSO treatment sites in Kenosha, Racine and Milwaukee, WI. In addition, bench scale anaerobic digestion studies were conducted to determine the effect of CSO sludges on the anaerobic digestion stabilization process. The results indicated that the dewatering of CSO sludges appears feasible when the sludges are first degritted, where required, and thickened prior to centrifugation. Preliminary economic estimates indicate that first investment capital costs for thickening-centrifiguation of CSO sludges ranged from 0.31 to 2.92 million dollars with annual costs of $49,500 to $659,300 per year when handling 4.0 to 36.5 tons dry sludge per day, respectively. |
