【 摘 要 】

Palm oil mill effluent (POME) generated from the palm oil industry is highly polluted and requires urgent attention for treatment due to its high organic content. Biogas plant containing anaerobic digester is capable to treat the high organic content of the POME while generating valuable biogas at the same time. This green energy from POME is environmental-friendly but the wastewater produced is still highly polluted and blackish in colour. Therefore a novel concept of combining coagulation with ozonation treatment is proposed to treat pollution of this nature. Several parameters should be taken under consideration in order to ensure the effectiveness of the hybrid treatment including ozone dosage, ozone contact time, pH of the water or wastewater, coagulant dosage, and mixing and settling time. This review paper will elucidate the importance of hybrid coagulation-ozonation treatment in producing a clear treated wastewater which is known as the main challenge in palm oil industry.
