Thermophilic digester
Webb10 mars 2024 · Thermophilic anaerobic digesters have higher rates of hydrolysis and acidification, thus complex organic material is faster converted to basic monomers producing more VFAs than mesophilic anaerobic digesters (see Tables 1 and 2) [ 36 ]. Large organic molecules cannot be directly consumed for electricity generation [ 37, 38 ]. Webb24 sep. 2024 · However, thermophilic digestion allows a higher amount of feed loading with lower retention time, due to its higher conversion efficiency.

Three temperatures (50, 55, and 60 °C) were tested on the thermophilic digester and 50 °C was found to be the optimal temperature for overall performance with 31% VS removal and 0.22 L methane/g VS fed. WebbA combination of a thermophilic digester and a mesophilic after-digester increases the conversion by 25%. Furthermore, Thermal Pressure Hydrolysis can be implemented as a pre-step. This leads to a further increased biogas production by 15%, a reduction of sludge, and an improved dewaterability. Combination of a thermophilic and mesophilic digesters
Webbthe digester set aside for thermophilic operation operate at 35 oC (96 oF). All these anaerobic digesters use steam injection for heating and gas re-circulation with draft tubes for mixing. There are 20 feeding events per day, making the feeding partially continuous. The plant digesters are roughly 14,000 m3 (3.7 million Webb1 apr. 2007 · Engineering Applied Biochemistry and Biotechnology The effect of feed-loading frequency on digester performance was studied on a thermophilic anaerobic digester with a working volume of 27.43 m3. The digester was fed 0.93 m3 of chicken-litter slurry/d, containing 50.9 g/L chemical oxygen demand.
Webb15 juni 2024 · Digesters are designed to run at different target temperature ranges. The temperature ranges are typically 86 - 100 F for mesophillic and 122 - 140 F for thermophilic. There are different populations of anaerobic microbes that thrive in these temperature zones.
