Abstract

Anaerobic digestion treatment of petroleum sludge increases Nigerian gross domestic product and enhance sustainable development as it yields biogas and biosolids fertilizer. The potential of anaerobic digestion for the treatment of Petroleum sludge was proved by a reduction in Biochemical Carbonaceous Oxygen Demand (BCOD) of the sludge from 6080 mg/L to 20.40 mg/L and Total Hydrocarbon Content (THC) from 57000 ppm to 1500 ppm. Gas Chromatography and Mass Spectrophotometry (GC-MS) result showed a decrease in concentration of Polycyclic Aromatic Hydrocarbons (PAHs) from 37.1 mg/L to 0.32 mg/L Napthalene; 33.43 mg/L to 8.24 mg/L Anthracene and 33.97 mg/L to 9.86 mg/L Phenanthrene. Anaerobic digestion of 200 grammes of the sludge gave 10,500
