The kinetic of Biogas Production from Municipal solid waste & Sewage using two stages Fermentation

Abstract

Municipal solid waste (MSW) management is becoming a serious issue in all over the world. Anaerobic digestion (AD) is one of the technologies to convert that waste into useful form of energy. To fulfill the need, the present paper deals with the review of various operating parameters and their effects on AD. This paper also reviews different pre-treatment methods including mechanical, thermal, chemical and biological methods to improve the effectiveness of AD of MSW. In this research work the quality and content of methane in biogas generated from biogas plant is improved by co-digestion of MSW, cow dung along with the urine with better carbon to nitrogen (C/N) Ration. We took number of experiment using different ratio of MSW and additives to improve biogas. Rigorous experimentations concluded that the co-digestion of the MSW, cow dung and urine in the proportion of (50:40:10) with equal amount water in a portable bio digester for anaerobic digestion results into better methane production with maintaining C/N ratio and reducing time duration for flammable biogas production.
