ABSTRACT: To treat the problem of
fossil fuel usage and greenhouse gas emissions, biogas is considered a potential source of clean
renewable energy. The aim of the work is to analyze the amount of biogas and ph
from cow dung when an anaerobic digester operates in the mesophilic mode. In
this study is presented the
experimental investigation of biogas production from cow dung as an alternative
energy resource. This is work using an 18 Liters capacity plastic as prototype
biogas plant, plant to inspect the anaerobic digestion in producing biogas. The
digester was batch operated and daily gas produced from the plant was observed for 30 days. The
digester was fed within the ratio of 1:1 of dung to water respectively. The
operating temperatures of the digester were maintained within mesophilic conditions.
The Biogas production from cow dung fluctuates from the first day to the
thirtieth day between 0 and 340 ml. The pH of cow dung is gradual reduction within the retention period.
