Abstract

Palm oil production contribute significantly to the national economies, encouraging rapid economic growth and minimizing rural poverty. However, palm oil production produce a Large amount of waste water known as palm oil mill effluent (POME) and was identified as one of the major sources contributed to the pollution across all water stream in Malaysia. The treated POME can be reuse and recycle back to the mill as a general purposes and boiler feed water if the characteristic match the standard and indirectly reduce the discharging of the POME. The treatment proposes in this study involve two stages of treatment which are microbubble pretreatment and ultrafiltration (UF) membrane separation. In microbubble separation, the raw POME was poured in the 2 m3 tank and operated for 5 hours. Sample was collected every hour and analysed for parameter such as BOD, COD, total solid, turbidity and color and then shows reduction up to 69%BOD, 27% COD, 81%/o total solid, 27%/o turbidity and 2% color respectively. This microbubble separation was used prior to reduce major fouling in the UF membrane separation. ln UF membrane separation, pretreated POME undergo UF membrane separation at different operating pressure which is 0.5, 1.0, 1.5, 2.0 and 2.5 bar using different type of regenerated cellulose (RC) membrane, 5 kDa molecularweight cut-off (MWCO) and 10 kDa MWCO. The results showed that microbubble separation coupled with UF membrane separation produce significant reduction up to 99% of all parameter. Finding shows the parameter reduction achieve the standard discharged limit of POME wastewater but not achieve the standard for water reuse and recycle.
