The main aim of this report is to reduce the retention period by adding microbes, pretreatment processes that is by Physical, Chemical and Biological like using the solar air heater with heat exchanger and this process ruptures the cell wall of sludge flow structure and facilitates release of intracellular matter into aqueous phase, improving biodegradability with lower retention time and higher biogas yield. Further, the residue of the Biogas plant can be treated as a manure to fertilise the Soil. After heating water up to 100oC in the solar water heater, maintaining the temperature of slurry taking heat capacity of both the fluids same. Gas yield of around 0.2-0.33 m3 /m3 will be obtained compared to conventional biogas plant i.e., 0.05m3 /m3 . Keywords: Cow dung; slurry; Solar water heater; Heat exchanger; biogas; water
