Abstract: The affordable and effective treatment of wastewater is critical issue for the developing countries. Various conventional treatment techniques; both biological and nonbiological are being tried. Disposal of domestic sewage of about 29000 MLD from cities and towns is a biggest source of pollution of water bodies in India. Chemical oxygen demand is the amount of oxygen required for the organic matter for its chemical decomposition and BOD is the amount of oxygen required for the biological decomposition. In the present work attempt is done to minimize the pollution parameters like COD, BOD by using bagasse flyash in batch and column operation. It has been observed that 90-95 % removal of organic matter can be obtained by using bagasse flyash. Also optimum values adsorbent doses; contact time and pH were obtained. These values were found to be 2 grams, 100 minutes and 6 respectively.
