How does temperature affect biogas production
WebAnaerobic bacteria survive in a broad range of temperatures, but there are two broad categories of methanogens. Medium-temperature (mesophilic) bacteria thrive between 20 and 45 °C (68 and 113 °F), and anaerobic digestion using mesophilic bacteria takes place between 30 and 38 °C (86 and 100 °F). WebThe temperature of high-temperature fermentation is controlled at 48°C–60°C, thus the decomposition speed is fast, resulting in a short processing time and high gas production, and it can kill parasite eggs effectively, but needs heating and insulation equipment.
