Indonesia's palm oil industry continues to grow rapidly and is largely agriculture-based. One ton of CPO produces about 2.5 m33 of wastewater. POME wastewater causes serious water pollution as it contains high levels of chemical oxygen demand (COD), biochemical oxygen demand (BOD) and oils. The effluent must be thoroughly treated so that it can be tolerated by the organisms present in the receiving system. Filtration methods (sand and activated carbon) have been shown to reduce turbidity of water samples and improve water quality as the process isolates and removes residual solid particles and flocs from the water. The use of membrane technology in dealing with domestic wastewater is quite popular. This is because membrane technology can reduce pollutant levels in water with high efficiency. POME has a turbidity value of 218.63 NTU, color 346.27 TCU pH 7.55 BOD 2,630 mg/L and COD 4,494 mg/L. variation of 10 cm silica sand and 30 cm activated carbon. This media has a cleanliness level of 94.3%, color 93%, BOD 75%, and COD 65%. 1 bar pressure is the ideal pressure to get rid of parameters, with a removal efficiency of turbidity 93%, color 97%, BOD 99%, and COD 97%. This study provides some ideas for further research, such as the backwash method in the filtration pre-treatment process and for membranes using different additive concentrations or other additives so that the resulting membrane has better properties and performance for water and wastewater treatment. This is done before the membrane is applied to determine the durability and ability of the membrane before use.
