Treatment of Distillery Spentwash by Electrocoagulation

V. Khandegar and Anil K. Saroh
Abstract—Effluent from distilleries, known as spent wash, leads to extensive soil and water pollution. Removal of pollutants and color from distillery effluent is becoming increasingly important from environmental and aesthetic point of view. Effluent from distilleries contains certain recalcitrant compounds. In the present work effort were made to reduce chemical oxygen demand (COD) from distillery effluent by electrocoagulation. The maximum COD removal efficiency of 98% was obtained at solution pH of 7.2 with a current density 17.9 mA/cm2 for electrolysis duration of 3 h. Further experiments were performed using aluminum sulphate as chemical coagulant to compare the COD removal efficiencies obtained by electrocoagulation and chemical coagulation.

Index Terms—Spentwash, electrocoagulation, coagulation, aluminum.
