Thermophilic anaerobic digester
Webb11 nov. 2014 · Inoculum from a mesophilic anaerobic digester treating municipal wastewater biosolids was successfully acclimated to thermophilic temperature (55 °C) with food waste as a substrate. Four laboratory-scale digesters were maintained at a loading of 2 g VS l −1 day −1 with one pair receiving TE supplementation. WebbAnaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. ... In contrast, while thermophilic digestion systems are considered less stable, their energy input is higher, with more biogas being removed from the organic matter in an equal amount of time.
