Study of Organic Constituents in Distillery Spent wash and Primary Treated Distillery Effluent (PTDE) with Different Dilutions

Abstract: Effluent that is released from distillery industries is known as spent wash which is the main reason for the damaging they caused on the natural ecosystem if there is no proper pre-treatment performed. A proper study is to be performed to detail about the physicochemical property of the effluent such as color, odor, total dissolved solid (TDS), chemical oxygen demand (COD), pH, biochemical oxygen demand (BOD), electrical conductivity, dissolved oxygen which are considered as the important parameters which will indicate the level of pollution of the effluent from different industrial. The present study was conducted to investigate the physicochemical characteristic and organic constituents of one of the distillery effluent found in distillery factory in Duggavati near Harapanahalli (tq) Davanagere . In investigation done by us we observed that the sample is lower pH and highly acidic in nature, higher temperature, higher concentration of chemical oxygen demand (COD) and biochemical oxygen demand (BOD) have been recorded. Disposing of the spent wash is one of the most important and present environmental problems faced by the world. The purpose of the study was to conduct and evaluate the physio-chemical characterization of spent wash effluent and analysis of PTDE and PTDE diluted with 50% and 75% of water.
