Pollution potential of spent wash: The distillery spent wash in general practice discharge into local water bodies which cause pollution in water, underground water and soil (Kumar et al., 1994). It also effects the aquatic life of these water bodies. A similar experiment was carried out by Singh, 2008 on
Distillery industries in several regions all over the world pose a serious risk, as it generates unpleasant compounds. Under such circumstances, it seeks an effective spent wash treatment, to eliminate the contaminants. Accordingly, this paper provides a relevant review regarding the distillery spent wash treatments, associated with the …
Disposal of distillery spent wash on land is equally hazardous to the vegetation. It is reported to reduce soil alkalinity and manganese availability, thus inhibiting seed germination [15].Kannan and Upreti [22] reported highly toxic effects of raw distillery effluent on the growth and germination of Vigna radiata seeds even at low concentration …
The ethanol distillery generates a huge quantum of undesirable dark brown coloured wastewater called "Distillery Spent Wash" (DSW) or "Vinasse" which has high COD and BOD. Presently, the disposal of DSW sustainably and efficiently is a major scientific, engineering, economic and environmental challenge in front of the distillery …
