Distillery Spent Wash

Distillery spent wash is the wastewater (effluent) generated during the alcohol process. To ensure effective treatment all distillery industries follow 1- 3 fold dilutions due to which a tremendous amount of spent wash is generated. Ethanol produced in distillery Industries is around 8 to 15 % by volume, which means that about 85 to 92 % wastewater content by volume. Thus distillery industries have a great adverse impact on the environment. Electrocoagulation treatment has been implemented to treat the cumbersome distillery spent wash. Continuous EC process using punched electrodes removes COD 94.77% and colour up to 78.57%. As the EC process has a limitation to decolourize the melanoidin present in distillery spent wash so ozone assisted electrocoagulation processes were implemented to treat the distillery industry. During the ozonolysis process, a carbon-carbon double bond of melanoidin started to cleavage with the remarkable increase in the decolourization. The ozone-assisted EC process degrades the COD 97.27 % and colour 98.72%.
