•Methanization of petrochemical wastewater and thickened manure activated sludge is researched.•Effect of the ten unlike flow rates of the substrates on methane yield is analyzed.•Optimal flow rate of the substrates for the best energy generation is obtained.•Energy and environmental assessment of anaerobic co-digestion have been quantified.•The result revealed that anaerobic co-digestion at flow rate of 370 ml/day is cost-effective.
The anaerobic biodegradability of a combination of petrochemical wastewater (PWW) and thickened manure activated sludge (TMAS) was measured with a 4.5 l pilot-scale continuous stirred tank reactor, ran at mesophilic (37 °C) condition. The anaerobic digestion, biogas generation, and energy assessment were analyzed for ten flow rates; 170, 220, 300, 370, 410, 475, 540, 600, 640 and 680 ml/day at mesophilic condition (37 °C). The analytical data revealed that the environmentally complied optimum flow rate was 370 ml/day, for bio-energy generation.
