Anaerobic bio-digestibility of blend municipal sewage sludge (MSS), condensed waste activated sludge (CWAS) and petrochemical wastewater (PWW) has been evaluated utilizing semi-continuous operation, anaerobic reactors worked during mesophilic (37 ºC) and thermophilic (55 ºC) states. Supplementation of a significant PWW portion (49 % of VS) in an MSS + CWAS combination brought about 2.94 times more methane production, 153 versus 450 mL/g volatile solids (VS) under 37 ºC furthermore 2.59 times more methane production, 198 versus 513 mL/g VS under 55 ºC. The supplemented PWW portion might have been not inhibitory for the system. Those effects of this work show the profit frommunicipal sewage sludge, condensed waste activated sludge and petrochemical wastewater co-digestion.
