Abstract
Generally distilleries based on cane sugar produce ETHANOL from Molasses in large quantities. This is the major product obtained in the industry in several countries of the world. are than 15.8 billion gallons per year of alcohol from molasses produce in total world’s production. The aqueous distillery waste is stream known as spent wash. It is a dark brown colored highly organic effluent and is approximately 11- 14 times more by volume of the actual product alcohol. The more complex substituent includes very high chemical and biological oxygen demand values with too vary pH values. This is high concentrated organic substituent and therefore distillery spent wash is acting as able vital source of renewable energy. Most industries usually discharge untreated effluents into the neighboring fields or drains. These effluents not only contain nutrient that may stimulate growth of many crops but also have toxic chemicals which may retard Germination Presently these technologies used by distilleries for treatment of waste are Bio-methanation followed by a two stage biological treatment and study with respect to pH values modifies the values near to neutral it y and disposal using water courses for utilization on land for irrigation process.
