INVESTIGATION OF ENHANCED ELECTROCOAGULATION-MEMBRANE PROCESS FOR WATER RECLAMATION FROM PALM OIL MILL EFFLUENTS
The process of electrocoagulation (EC) enhanced with adsorbent addition, as a pre-treatment for ultrafiltration membrane, is widely unexplored in oil palm-based wastewater treatment. Utilizing predetermined EC operational parameters and a defined activated carbon (AC) dosage for biotreated palm oil mill effluents (BPOME), membrane fouling was studied during crossflow membrane filtration at 0.5 bar transmembrane pressure and 1 kDa membrane pore size. The dominant fouling mechanism in membrane filtration without EC-AC pretreatment of BPOME, was cake formation, which was determined through Hermia’s pore blocking models. However, after EC-AC pre-treatment, the membrane fouling was mitigated. Moreover, the pre-treatment process, AC assisted EC, sustainably enhanced the final treated effluent quality in addition to enhancing fouling mitigation in the subsequent membrane filtration. The removal of Total Suspended Solids (TSS), turbidity and color were nearly 100% and Chemical Oxygen Demand (COD) was 99.7% removed with final value of 5±1 mg/L, which is within the range of reusable water standards. ABSTRAK: Proses elektrokoagulasi (EC) yang ditingkatkan dengan bahan penyerap, adalah pra-rawatan bagi membran penuras ultra.
