description of sludge drying process universaldrying

Description of Sludge Drying Process Biomass/sewage sludge from digestion towers or sedimentation tanks is pressed using a de-watering screw or filter press to achieve approximately 25% dry matter. Wheel loaders, conveyor belts, or screw conveyors pass the pressed biomass/sewage sludge into the 1400 ft3 (40 m3) push-floor container of the dryer
