摘要：In this study, the decolourisation of Palm Oil Mill Effluent (POME) was investigated by electrocoagulation (EC) batch reactor utilizing aluminium plate electrodes. POME was characterized physicochemically for colour, chemical oxygen demand (COD), pH, conductivity and turbidity. The colour of POME was observed to be dark brown of 2707 PtCo with a high organic content of COD at 3909 mg/L and high turbidity at 755 NTU. The electrical conductivity was at 12.82 mS. The influence of various operating parameters such as pH (3 to 11), applied voltage (5 V to 20 V) and plate gap (7.5 to 11.5 cm) to the POME colour removal were investigated as well. The highest colour removal was spotted at pH 5, applied voltage of 20 V and plate gap of 9.5 cm with corresponding colour removal percentage of 89, 79 and 78%, respectively. The EC flocs examined using FESEM exhibited the amorphous spherical and rod-like shape structure.
