Significant research conducted in Malaysia demonstrates that membranes can cost-effectively treat palm oil mill effluent (POME). Research efforts have demonstrated that membrane technology is suitable for treating POME, as it involves a continuous process producing water of consistent quality. These efforts have demonstrated that clean water has been reclaimed and recovered from POME using ultrafiltration (UF) and reverse osmosis (RO) membrane systems. These systems are coupled with coagulation, flocculation, and adsorption units as pretreatment through a pilot plant. The final RO unit of the pilot plant reduces the soluble chemical oxygen demand (COD) and biochemical oxygen demand (BOD) content in POME to meet the limit of the effluent discharge standard. This treatment also removes more than than 99% of BOD from the raw POME along with 99% of the total dissolved solids, organic nitrogen, and 99% of ammonia nitrogen.
