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.
