Abstract

There is an urgent need to find best suitable economic technology to knock out the problems due to distillery industries creating pollution and ecological imbalance. In the present study electro-coagulation treatment is carried out by using different combination of aluminum and iron electrodes in a batch reactor. Also chemical coagulation treatment is carried out by using alum and lime dose to treat distillery spent wash. Maximum 96.09% colour removal was obtained by using Al-Al electrodes for pH 8 and maximum COD removal was obtained 85.7 % by using Al-Al electrodes for pH 3. Further experiments are carried out by using alum and lime coagulant dose to treat distillery spent wash maximum 66. 27 % COD was removed by using alum. Alum is more effective than lime to remove chemical oxygen demand.
