Sewage Sludge Treatment

Thermal sludge treatment

Since 2006 Michaelis has been sucessfully using its patented moved bed system.
This system can treat a wide variety of fuels such as municipal waste, hazardous waste, biomass, refuse-derived fuel, plastics and also sludges.
The Michaelis moved bed system has decisive advantages over the fluidized bed process.
