ORGANICS REMOVAL FROM DOMESTIC WASTEWATER UTILIZING PALM OIL CLINKER (POC) MEDIA IN A SUBMERGED ATTACHED GROWTH SYSTEMS

To meet the discharge requirements, new treatment plants are designed as extended aeration systems with anoxic tanks to meet the new regulations. In this study, submerged attached growth made from palm oil clinker (POC), was introduced into conventional activated sludge systems. In the activated sludge system, aerobic and anoxic chambers were introduced to promote nitrification and denitrification. The performance of POC submerged system was monitored and compared to a biological activated sludge system. The performance on the removal of an organic was measured from COD, TSS, MLSS, and MLVSS. The rate of removal average for COD result of biomass improved POC in a POC reactor with attaching growth system POC mode is COD 30-50 mg/L, TSS 10-15 mg/L, MLSS 700-800 mg/L and MLVSS 600-700 mg/L for the POC reactor as attaching media. Therefore, using POC as an attach growth system can reduce the organic contaminant in effluent discharge
