Webbiogas: [noun] a mixture of methane and carbon dioxide produced by the bacterial decomposition of organic wastes and used as a fuel. WebTypical HRTs of septic tanks and biodigesters are 2 and 20 days respectively, meaning that tank sizes of biodigesters are about 10x bigger than septic systems. For example, if a household generates an average daily wastewater flow of 1m3, a septic tank size of 2m3 is required, while a 20m3 tank size would be required for a biodigester. church basement ladies bloomington mn
