Digestate Drying
Dryer Applications
Sewage Sludge Dryer
Filter Cake Range 15-35% DS (Dry Solids), Fuel Options: Natural Gas (NG), Renewable Natural Gas (RNG), Combined Heat and Power (CHP), Propane or Combination, Class A Sludge produced, Disposal Cost Reduction. The sewage sludge is fed from digesters or sedimentation/storage tanks using a sludge loading container into a screw conveyor. There the sludge is mixed to a higher DS content before it enters the dryer. During the procedure, the hot exhaust gases are transported from the gas and biomass combustion directly into the material dispersal of the dryer. This allows for almost ideal physical conditions for the evaporation of water.
Digestate Dryer
Digestate Slurry Range 3-10% DS, Fuel Options: Combined Heat and Power (CHP), Renewable Natural Gas (RNG), Natural Gas (NG), Propane, Uses: Fertilizer, Bedding, Animal Feed, Class A Pellets produced. Biogas operators face increasing challenges in respect to the liquid manure ordinance, storage issues, the nutritional balance of fertilizer, and the application of liquid digestate. Pelletizing digestate is an excellent way to combat these challenges, producing a Class A product in accordance with the EPA guidelines.
Pyrolysis
Sludge Pyrolysis
Pyrolysis is the heating of organic material, such as biomass, in the absence of oxygen. Because no oxygen is present the material does not combust but the compounds that make up that material thermally decompose into combustible gases and charcoal. The produced bio(based)char can be seen as carbon sequestering agent having a CO2 positive balance and helps to fulfill worldwide requested climate goals.
