Abstract – The human excreta, cowdung, vegitable wastes are presently used us commom substrate for biogas generation.Production of renewable energy recycling of nutrient and production of waste volumes are some of the advantages of the anaerobic digestion.It not only reduced the cost of waste treatment through a reduction in the volume of waste,but also the tannery waste generate high revenue to the company. Otherwise the nutrients of the organic wastes are lost in landfills, nitrogen in particular.In this study, to maximize methane yield, preparing of slurry of the tannery waste was chosen as a treatment task. In digestion a consortium of microorganisms is involved which are catalyzing a complex series of biochemical reactions resulting in mineralizing organic matter producing methane and carbon dioxide. In this study UASB (Upflow Anaerobic sludge blanket) reactor working biogas digester using tannery water as the substrate provide the consortia. The main steps in anerobic didestion are hydrolysis acidogenisis. Substance such as carbohydrate are rapidly fermented (Bryant 1979). Some of the more commonly used indicators include volatile fatty acids (VFA), acids effulent COD,BOD concentration and pH. In this study, the feasibility of degradation of the tannery waste water in an UASB to be investigated. The volume of the gas produced, analysis of pH, total solids(TS),volatile solid(VS) and elements contents in the outlet and off-line analysis of the gas composition were monitored.
