Oleochemicals industry consumes large amount of water and chemicals for processing crude oil that contain high chemical oxygen demands (COD). Thus, the discharge wastewater containing high COD concentration is the major factor that contribute to water pollution. An effective wastewater treatment is required before discharge to environment. Lab scale submerged bed biofilms reactor (SBBR) was operated continuously for the treatment of Oleochemicals wastewater. Cosmoballs® packing with carrier A (green sponge) were used for bacteria growth in the SBBR. Water analysis such as chemicals oxygen demand (COD), pH and Turbidity were analysed. The optimum condition for SBBR when Cosmoball® carrier and carrier A were used as packing materials with flowrate of 100ml/min and 1:1 ratio of activate sludge (mixed culture) volume to SBBR volume. The results indicate that COD was reduced, initially 6000 ppm to 140 ppm while turbidity and pH after treatment were recorded as 9.0 and 7.0 respectively which were fulfilled requirements by Department of Environment (DOE) Malaysia.
