Digester temperature - to heat or to cool?
Maintaining an optimal digester temperature is a key aspect of maximising biogas production and overall process efficiency in anaerobic digestion. Not only is temperature essential to maintain a healthy colony of bacteria, but it can reduce retention times and improve material circulation – thereby helping to increase the production capacity of the whole process. In terms of temperature ...

Floating Cover-China - Case Study
" We have Thermophilic digested biological sludge, digested at 55 degrees. This is done in the digester, from which the sludge is fed to a open storage tank. Subsequently the sludge is dewatered, and the water from the dewatering is led to an "Anita Mox' process. This process should preferably stay above 18" degrees, so it is important that the temperature does not drop too low in the storage ...
