Summary
Downflow fixed bed reactors operated at 35°C, were sucessfully used for the anaerobic digestion of a petrochemical effluent. COD reductions of 93–95% were found at an optimum retention time of 2.3 days and a loading rate of 4.7 kg COD/m3/d. The amount of biogas produced was 0.88 m3/m3/d (STP), with a methane content of 90–96%.
