Mesophilic digester

Mesophilic digester or Mesophilic biodigester is a kind of biodigester that operates in temperatures between 20 °C and about 40°, typically 37 °C. This is the most used kind of biodigester in the world. More than 90% of worldwide biodigesters are of this type. In contrast, thermophilic digesters are less than 10% of digesters in the world, as it's more difficult to maintain the higher temperatures in a treatment plant, and they typically perform worse at separating liquids out of the sludge.[1] Mesophilic digesters are used to produce biogas, biofertilizers, and sanitarization mainly in tropical countries such as India and Brazil.
