WebFeb 7, 2024 · A longer retention time will provide a greater degree of sludge stabilization and allow intimate contact between the biomass and the liquid ow during the treatment process (Keay, 1981). WebOct 1, 2010 · Evolution of biogas, methane production and VS-reduction under thermophilic and mesophilic fed-batch mode digestion of dewatered-sewage sludge at different solid retention times (SRTs). The OLR increased from 2.5 kg VS m −3 day −1 for 25-day SRT to 5.7 kg VS m −3 day −1 for 12-day of SRT.

The amount of gas produced per unit of volatile substrate charged into a polyethylene digester showed a linear increase with retention time. The total biogas produced from poultry and cassava wastes was 1.508m3 and 1.179m3 for 42 days and 79 days respectively. The ambient ... WebThe hydraulic retention time (HRT) affects the contact between the substrates and microorganisms. ... An increase in OLR results in higher biogas production rates but excessive organic loading will lead to process inhibition, thus decreasing gas production.
