Abstract

Research work was conducted to investigate the production of biogas using mesophilic anaerobic digestions. The organic waste utilized for bio gas appeared to produce less bio gas in the initial state up to 5 days due to temperature changes, then the gas production gradually increases. From the experimental set up, it was discovered that biogas generation was not uniform. Cow dung, food waste and agriculture wastes were used as organic waste for loading the anaerobic digester. Catalyst such as lime, hydrogen peroxide and silica gel were added to enhance the reaction. From above investigation, it is conceivable that the COD reduced gradually in the digester. Biogas production were fluctuating throughout the study period. The ideal measure of gas production in the range of 320 mg/l was obtained by adding hydrogen peroxide but for a period of 30 days experiment cumulative bio gas production measure is 4697 mg/l, which is achieved by adding lime as catalyst. Efficient bio methanation of grinded organic waste can be achieved by adding lime in most economical way.
