Process Study of Biogas Produced from Cow Dung and Water Hyacinth in a Single Phase Digester Reactor

摘要

Renewable sources of energy are steadily gaining importance and leading the way is methane gas obtained from biomass waste fermentation process in biogas plants using natural fermentation and decomposition. Biogas production by anaerobic digestion is seen as the model way to treat waste with different biomass waste having different biogas potential processes to produce biogas which is used to generate electricity as efficiently as possible and as a substitute for fossil fuel. In this study, process performance was investigated with biogas produced from cow dung and water hyacinth in a conventional single phase digester reactor with retention time of 30 days. The analyses of the result obtained showed that 0.11 m~3 of biogas was produced optimally on the fourteenth day at a temperature of 30°C and a pH of 7 with study suggesting that for optimization of process and production of biogas, a pre and post treatment technology should be in place to ensure pathogen free products with a uniform operating condition established in the digester system.
