|Abstract:||Reduction of pollution load coming out of the industries and thus making the industrial effluent match the quality standards set up by pollution control bodies is the foremost requirement to save our surface streams from environmental degradation. This study pertains to the treatment of effluent from Board Mill using physico-chemical methods. The study reveals that most of the solid matter present in the wastewater is in colloidal form; also it is a moderate BOD wastewater. Hence the suggested treatment is plain settling followed by coagulation with alum. COD and SS removal due to different alum dosage at various adjusted pH values of wastewater has been studied to ascertain optimum dose of alum as also optimum pH value. Jar test set up was employed to apply alum dosage and NaoH was used to adjust pH. With the aim to achieve further COD reduction, diffused aeration was followed .by chemical treatment, using oxidants. Parallel studies with different dosage of hydrogen peroxide and chlorine at different contact period were performed. The overall results show that substantial pollution load is reduced with the above set of treatment. Thus physico-chemical method appears to be a good choice.|
