Mesophilic vs thermophilic digestion: technical and operational comparison
Anaerobic digestion can operate in a mesophilic regime (35-40 °C) or a thermophilic one (50-57 °C). The thermophilic regime is faster (hydrolysis runs 2-3 times quicker, with retention times of 12-20 days versus 20-40) and hygienises the digestate, but it is more sensitive to ammonia and consumes 30-60 % more heating. The mesophilic regime is […]
