Utilization and treatment of dairy effluent through biogas generation-A case study

Biogas is an alternate source of energy and after realizing the potential of biogas, a National level programme was initiated in India during 1970s. Present study on biogas generation from dairyeffluentand control of waterpollutionhas beenviewedwiththe aim of controlofwater pollution through treatment of dairy waste as well as generation of biogas. Environmental parameters like Temperature, pH, Biological Oxygen Demand (BOD) & Chemical Oxygen Demand (COD) was taken in to account. No change in the average value of temperature and pH was recorded but BOD and COD reduced to the extent of 50 percent. All parameters however showed statistically significant differences at 5 percent level between inlet and outlet point. Gas generation fluctuated between.5m³/day to maximum 4.5 m³/day with an average of 3m³/daywas recorded.
