Palm oil mill effluent treatment using hybrid microbial fuel cell-activated carbon system

Palm oil mill effluent (POME) is a thick brownish liquid which causes serious environmental pollution due to its high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) and POME can contaminate watercourses if discharged without proper treatment. Hybrid microbial fuel cell-activated c...
