Abstract:
This is an experimental study on produced biogas volume and volume from co-digestion of cow dung and food waste. This study was carried out at ambient condition. A gas meter was used for the measurement of gas composition, biodigester operating parameter were measured using a multi meter while gas volume was obtained from the observation of the floating drum. Four floating drum digesters were used for the experiment. The digesters held 3300 g of feed each with varying ratios of 70:30 (Sample A), 50:50 (Sample B), 40:60 (Sample C), and 30:70 (Sample D) of cow dung to kitchen waste respectively. The dilution ratio was 1:3 of feed to water which had a retention time of 30 days. The gas composition (CH4, CO, CO2, H2S), substrate pH and temperature were monitored to observe the changes. The results gotten were graphed and tabulated. The gas gotten from the biogas burnt which shows that the biodigesters produced methane (CH4) of more than 40% of the gas composition at certain points during the retention time.
