Characterization and Storage of Biogas Produced from the Anaerobic Digestion of Cow Dung, Spent Grains/Cow Dung, and Cassava Peels/Rice Husk.

Abstract

Cow dung, spent grains/cow dung, and cassava peels/rice husk wastes were treated in the digester of volume 0.971m3. Each waste was mixed in different ratio, depending on the nature of the waste. Fixed dome plastic biodigester was used and the digestion of waste was undertaken by batch-type anaerobic digestion. The digester operated at mesophilic temperature (20-40oc). Gas chromatography was used to quantify the different component of biogas produced. Volume and pressure of Biogas stored is the cylinders were tabulated. The total viable count determination for bacteria and proximate analysis of the wastes was done. (Keywords: biogas, chromatography, batch-type,
