Abstract
Palm oil mill effluent (POME) contains high biological oxygen demand (BOD) and chemical oxygen demand (COD) Agra base wastewater is the concern of biodegradable treatment methods. Consequently, the BOD / COD ratio has a significant effect on the biodegradability of wastewaters. This study investigates effects of aerated sequencing batch reactor (SBR) system augmented by zeolite used for treatment of POME. Not only, the BOD / COD ratio increased from 0.11 in raw POME to mean 68.15% increase after aeration in the SBR system, but also, the most obvious finding to emerge from this study is that, aerated SBR could be considered as an effective method for enhancing BOD/COD ratio for qualifying post treatment by biotreatment methods.
