The effect of an oxidative co-treatment on anaerobic digestion of a mixture of primary and waste activated sludge was investigated. The oxidant used in this study was hydrogen peroxide (H202). A maximum improvement in solid destruction of 15.2% was achieved in the overall process, with a dosage of 2.0 g H2O2/g influent volatile suspended solids (VSSinfluent. All configurations operated at this dosage also showed statistically significant increases in solids removal. A statistically significant enhancement in overall solids destruction was observed for the lower oxidant dosage (0.5 H2O2/gVSSinfluent. Surprisingly, for 1.0 g H2O2/gVSSinfluent, only one of the three configurations involving oxidative co-treatment showed significant increases in solids destruction. Special attention was paid to the performance of this process relative to fecal coliforms destruction. Class A biosolids were obtained for all the different hydrogen peroxide dosages used when oxidative co-treatment is combined with a two-stage anaerobic digestion process, Water Environ. Res., 78, 691 (2006). [ABSTRACT FROM AUTHOR] |
