Abstract

Water reclamation is a process by which waste water from industries was processed by physical, chemical, biological or a combination of these treatments so that the water can be reclaimed or returned to the environment safely. In the ethanol production, the total volume of wastewater released is 10 times more that the ethanol produced. Currently anaerobic treatment is the most widely used to reduce COD and BOD level from the waste water. A laboratory scale External Membrane Bio reactor (E-MBR)is used to treat the distillery waste water collected from Up flow anaerobic sludge blanket (UASB) unit. The objective of the present research was to enhance the treatability of distillery effluent using MBR and was studied COD, TDS and pH changes were investigated and high treatment of distillery effluent has been achieved. The performance of this study is evaluated based on the removal of colour, pH changes observed at various stages of this treatment process and found that maximum decolourisation of 92% and 95% reduction in COD level.
