Colsen's technology complying with US EPA biosolids class A

Thermophilic anaerobic digestion (TAD) of sludge is not only a game changer for the energy balance of a sewage treatment plant (STP), but also eliminates pathogens below safe levels. 

Dr Merijn Picavet wrote a paper to show how Colsen’s TAD fits in as a technology for sludge treatment resulting in Biosolids Class A, the highest level of biosolids that may be achieved according to the United States Environmental protection Agency (EPA).
