Influence of Potash on Biogas Production from Cow Dung and Food Waste

This study investigated the production of biogas from food waste co-digested with potash and cow dung as inoculant. The aim this was to determine amount generated substrate. Experimental research design used it carried out at Uturu, Abia State, Nigeria. 4% 12% concentrations substrate were mixed fed into anaerobic digesters labeled B1 B9 for 90days. Result ultimate analysis showed oxygen (41.33%,14.06%), nitrogen (3.23%,1.48%), carbon (36.50%,29.67%) PH value(6.25, 8.47) respectively. quantity in different (B1-B9) 1341.2, 1668, 1784.5, 1945.2, 1941.7, 2159.2, 2328.1 2428.5m3/day Analysis Covariance (ANCOVA) model volume that there significant contributions predicting produced F (9,611) = 2684.28 p-value <0.0001. effect on revealed an increase gas by substrates added. Digester lowest potash, 1341.2m3/day while highest flame test burned a blue flame. findings can be co-digestion waste, dung. Thus, could have helped boost production. More studies should done how local organic materials useful more biogas.
