WebJul 1, 2010 · Abstract. The quality of the mixing affects directly the hydraulic residence time of the feed substrates in the digester, homogeneity of the agitated material, biogas yield and total energy consumption of biogas plants. In practice, in most of the biogas plants the own energy demand is 4-10 % of the total produced electric energy. WebThe biogas can occur within a week and its composition composed of 63.1% CH4, 34.4% CO2, 2.2% of oxygen and 0.3% of other gases such as nitrogen and hydrogen. The retention time of cassava pulp fermentation in the appropriate proportion is about 41 days. An increase of cassava waste can enhance the amount of biogas production.
