Spent wash from grain and bagasse based distillery can be treated in our evaporation system. Integrated Evaporator SVAAR also offers integrated evaporation system where alcohol vapor are the primary heating source to drive the evaporation process.
Apr 22, 2019 Distillery spent wash is a high-organic liquid waste product generated during alcohol production. Typically, the organic load of spent wash is reduced through biomethanation by which organic material is microbiologically converted under anaerobic conditions to biogas. The resulting waste stream is referred to as biomethanated spent wash.
Nov 14, 2018 Effect of distillery spent wash DSW was studied on plant and ratoon crop of on three sugarcane Saccharum spp. hybrids genotypesviz, CoS 95255 early maturing and high sugar, CoS 767 mid-late and medium sugar and BO91 late maturing and medium sugar. The DSW was applied through irrigation water during early growth stage 60 and 90 DAP at three different
