Removal of BOD contributing components from Sugar Industry Waste water using Bagasse Fly Ash-Waste material of Sugar Industry

Rapid globalization lead us on the way to industrialization. Sugar industry is one of the biggest consumer of water, and can also introduce serious pollutant to the environment. To minimize this industrial wastewater pollution, advanced wastewater treatment techniques, such as adsorption are economically and environmentally essential in the removal of organic and inorganic compounds. The present study focuses on the use of low cost adsorbent sugarcane bagasse fly ash to adsorb BOD content of the combined wastewater of sugar industry. Bagasse Fly ash with specific surface area of 2637.784 cm2/gm is used as a clarifier to the combined waste water of Sugar mill at room temperature. The different dosage of bagasse fly ash is kept in contact for 24 hours and analyzed before and after treatment. The results of BOD removal follow the Freundlich and Langmuir adsorption isotherm.
