PENGOLAHAN LIMBAH PALM OIL MILL EFFLUENT (POME) MELALUI KOMBINASI PENCERNAAN ANAEROB DAN KOAGULASI DENGAN RASIO INOKULUM/POME (5/95; 10/90; 15/85; 20/80; 30/70)
The palm oil industry generates Crude Palm Oil (CPO) as its primary product, which is extracted from the mesocarp of oil palm fruits. In 2021, CPO production reached 53.9 million tons and is projected to increase to 70 million tons by 2025. The processing of one ton of oil palm into CPO generates approximately 0.7 – 0.8 m³ of Palm Oil Mill Effluent (POME). Due to its high Chemical Oxygen Demand (COD) levels, ranging from 15,013 to 86,300 mg/L, POME cannot be discharged directly into water bodies as it causes environmental pollution, thus requiring further treatment. This study utilized anaerobic digestion and coagulation methods, aiming to meet effluent quality standards while producing biogas as an alternative energy source. The anaerobic digestion was conducted using a simple reactor design under batch conditions, while the coagulation process involved stirring at a speed of 200 rpm. The objective of this research was to determine the effects of various parameters on the anaerobic and coagulation processes of POME. The variables included the inoculum/POME ratio (5/95, 10/90, 15/85, 20/80, 30/70) for anaerobic digestion and the application of alum at an optimum dosage of 6 g/L for the coagulation of digested POME. The results indicated that the 15/85 inoculum/POME (v/v) ratio was the optimal variation, yielding a cumulative biogas production of 140.514 mL/g COD over 15 days. Anaerobic treatment of the 15/85 inoculum/POME (v/v) sample resulted in a Total Solids (TS) value of 27,500 mg/L. Following the coagulation stage, the final TS and COD values were recorded at 29,000 mg/L and 20,550 mg/L, respectively.
