Experimental Investigation On Sugar Industry Effluent By Using Upflow Anaerobic Sludge Blanket Reactor

Abstract

Now a days, the environment is suffering due to energy ( renewable and non-renewable). Due to this condition we had choose this project, in our project we took sugar industry effluent, and characterized the effluent. The effluent had more amount of organic compound as well as heavy metals, so that was suitable for producing the biogas. Due to the organic compound digestion process the biogas was produced. The organic compound was largely digested by anaerobic process. Anaerobic process means with out oxygens the bacteria was digested by bacteria’s. for anaerobic process we take UASB (Up flow anaerobic sludge blanket reactor) . The reactor height is 1000mm and it diameter is 12.5mm. The reactor that had four stages, they are respectively hydrolysis, acidogenesis, acetogenesis and methanogensis. In that fourth stage the bio gas was produced. During the process of UASB Reactor the effluent characteristics especially the pH was maintained. So to maintain the pH value we add some coagulants. We investigate the sugar industry waste water by adding two type of coagulants they are namely chemical and natural coagulants. At last we got the result, when compare to chemical coagulants the natural coagulants produce more amount of bio gas.
