Comparative Study of Biogas Production from Municipal Solid Waste using Different Innoculum Concentration on Batch Anaerobic Digestion
Keywords:Anaerobic digestion, Volatile solid degradation, Municipal solid waste, biogas yield.
In this study batch anaerobic digestion of municipal solid waste was carried out for 60 days at room temperature for two different inoculums (cowdung and sewage sludge) at varying inoculums concentration 10%, 20%, and 30%. The performance of reactors was evaluated by measuring the daily biogas production. Effect of organic solids concentration and digestion time on biogas yield was studied. The biogas yields at the end of the digestion from the reactors cow dung as inoculum were 337.365ml/gVS, 481.95ml/gVS and 567ml/gVS similarly sewage sludge as inoculum were 214.775ml/gVS, 321.198ml/gVS and 383.52ml/gVS respectively.Â Â About of 65.45%, 80.06%, 86.655%, 60.25%, 65, 89%,and 72,78% Volatile solid degradation were obtained during the loading in reactors.
