Characterization and optimization of the performance of an integrated ultrasonic membrane anaerobic (IUMAS) in treating pome as substrate

Palm oil mill effluent (POME) is a highly polluting wastewater with high chemical oxygen demand (COD) and biochemical oxygen demand (BOD). These causes severe pollution to the environment, and water resources. Traditional ways of treating POME are disadvantageous from both economic and environmental...
