Abstract: Effluents from distilleries, tanneries, textile and paper industry with varying BOD pose severe environmental problem. To improve the quality of effluent, oxygenation has been tried out. In this work varying effluents to water (E/W) ratios (4/96 to 80/20) was experimentally studied on distillery effluent and DO analyzed. It was found that up to a ratio of 60/40 the DO increased and further increase in E/W ratio showed oscillatory response. The data on DO vs. time fitted a first order model with an error of 1.73 %.


Keywords: Distillery effluent, Aerobic process, Modeling E/W
