Abstract

Biogas production from cowdung in digesters with and without polyvinyl chloride plugs (PVCP) was investigated with a view to improving the efficiency of methane generation and reducing the overall cost of production. A maximum yieM ofO.419m 3 ofbiogas/kg VS added, with 62% methane content, was attained in the digesters packed with PVCP and fed with cowdung slurry of 8% total solids at a 30-day hydraulic retention time. The yield was about 2-3 times higher than the control digesters. The use of P VCP suggested the possibility of improving the performance of commercial digesters, which are commonly employed in India both in rural and urban areas, with a slight increase in the overall cost of fabrication and installation.
