Comparative Study of 'BOD' and PH of Distillery Wastewater

Industrial processes create a variety of wastewater pollutants which are difficult and costly to treat. Production of ethyl alcohol in distilleries based on cane sugar molasses constitutes a major industry in Asia and South America. The world’s total production of alcohol from cane molasses is more than13 million m3/annum. The aqueous distillery effluent stream known as spent wash is a dark brown highly organic effluent and is approximately 12-15 times by volume of the product alcohol. It is one of the most complex, and strongest organic industrial effluents, having extremely high BOD values. of organic load. The paper reviews the status of BOD values before and after treatment of the distillery wastewater
