The dried sludge is much easier to store, transport, and package. How Do Sludge Dryers Work? Often a sludge dryer is used for the final drying of sludge or digestate. Dewatered solids enter the dryer's inlet and begin the process of drying as heated air is applied. The airflow moves the dewatered product into a collection system.
indirect drying by a thin-film evaporator: the dried sludge is pre-dried to dry content levels of 40% to 50%; mechanical extrusion: the sludge is forced through a perforated grid to form pellets; direct drying by the belt dryer: the final dry content of the pellets is between 65% and 90%
A sufficient degree of dewatering of sludge is essential for sludge extruding and drying in belt dryers.
