BIOREMEDIATION OF SUGAR WASH USING NATURAL SCAVENGERS

Effluent emanating from distillery industries is dark colored, acidic, with high biological oxygen demand, chemical oxygen demand,and liquid consisting of biodegradable organic and inorganic constituents, which cannot be disposed directly into water bodies. Hence, the effluent released from a distillery industry was collected and were analyzed for various physico-chemical characters. Due to the higher strength of the spent wash, it was diluted with the sugar effluent at 1:1 ratio (spent wash 50 ml + sugar effluent 50 ml). Thus the obtained sugar wash was biologically treated using the indigenous microorganisms. The isolated microorganisms were identified asEnterobacter(T1)sp.,Corynebacterium(T2)sp.,Microccocus(T3)sp.,Corynebacterium(T4)sp. Upon treatment with the isolated microorganisms the level of TDS, COD was found to be lowered along with the color removal. As a level of reduction 12.76% of TDS was found to be reduced with Corynebacterium(T2)sp., and 16% of COD and 9% of color removal with Corynebacterium(T4)sp., with a 96 hours of treatment. Consortia microbial treatment has shown 28% of color removal, 32% TDS and 35% of COD reduction at the same detention time. The results revealed that the possibility of using indigenous micro – organisms especially consortia for the treatment of sugar wash.
