Pollution caused by dairy effluents is a serious problem throughout the world. The major source of waste water is from dairy industry. The effluent from dairy processing unit affects the environment. As a solution our aim is to produce bio-gas from diary wastewater. There are various treatment technologies, among them anaerobic treatment technology is simple and encouraged due to the following advantages such as low cost of construction, pH stability, low maintenance and repair. The biogas is a renewable fuel which can be made using a relatively well known technology. The hazardous pollutants of dairy wastewater can be reduced by anaerobic digestion. For the production of bio-gas we use a batch reactor of capacity 2L. Diary wastewater as a substrate and cow dung as an inoculum is mixed in a definite proportion and fed into the digester. The required physio-chemical parameters (pH, COD, T.S, and V.S) which influence the bio-gas production are studied before and after the digestion process. After the biogas production COD level was reduced up to 36%
