PALM OIL MILL EFFLUENT TREATMENT AND BIO-ENERGY GENERATION USING HYBRID MICROBIAL FUEL CELL – ADSORPTION SYSTEM

Palm oil mill effluent (POME) discharged without effective treatment into watercourses can pollute the water source due to its high acidity, biochemical oxygen demand (BOD), and chemical oxygen demand (COD). As an approach to overcome the limitation of the existing POME treatment methods, a hybrid...
