During the recent days, investigations in pollution control of industrial effluents become one of the pinnacle problems of the society. Molasses used in distilleries for production of alcohol by fermentation process, generating highly organic and colored wastewater which is released as distilled spent waste. Treatment with microorganism is widely used to reduce 65-70% COD and 80-85% BOD level from the wastewater by converting the organic content present in it. This work assess the optimization ratio of coagulant and flocculant by RSM-CCD (10% PAC, 10% Maxfloc 508 and 0.2% Maxfloc C22). The R2 value of coagulation was calculated as 0.99194 and Adjusted R2 value of 0.984695 with predicated R2 value as 0.938909. The microorganism isolated from UASB sludge was used as a microbial degradation of the spent wash waste after coagulation and further on subjected for EMBR and filtration. The suitability of E-MBR for distillery wastewater treatment for the maximum decolorization upto 90% using membrane filtration that can be adopted to treat this bio-methanated distillery spent wash (BMDS) water and to make digested spent wash fit for reclamation. A laboratory scale External Membrane Bio reactor (E-MBR) is used to treat the distillery waste water collected after digestion. The performance of this study is evaluated based on the removal of colour, pH changes observed at various stages of this treatment process and to optimize the coagulant dosage
