Abstract

The performance of a membrane bioreactor (MBR) far treating palm oil mill effluent (POU) has been studied. The objective of this study was to observe and evaluate the performance of MBR for POME treatment. A high strength POME with organic loading rate uf 1.4 kg BOD per m³d was fed into an aerobic MBR. The MBR was operated with constant flux of 15 LMH. The reactor was operated at a mixed liquor suspended solid (MLSS) concentration about 4.5 g/l. The removal efficiency of COD, SS, and Turbidity were achieved 88%, 99%, and 99% respectively. The system were also capable to remove 61% of BOD, 75% of colour, 74% of TN, and 49% of TP. To observe the effect of biomass on membrane fouling, activated slugde for MBR was investigated ta determine concentration of carbohybate for soluble microbial product (SMP) and extracellular polymeric substances (EPS). The aerobic MBR was found to be able to degrade POME significantly and high quality effluent could be reused for various other applications.
