SMS offers sludge drying systems with horizontal thin film dryers for treatment of sludge from municipal as well as from industrial waste water treatment plants. Variations of this sludge treatment process are: Pre-drying up to 35 to 50 % dry solid content before incineration in fluidized bed incinerators 65 to 75 % dry solid content before combined incineration with garbage, composting or landfill Full drying up to 85 to 95 % before thermal utilization as bio-fuel for cement kilns, coal fired power stations, pyrolysis, gasification or other conversion processes before composting and agricultural usage as fertilizer and for soil reclamation In all these drying processes the thin film dryer is the first choice.

The wet product fed through the inlet nozzle is picked up by the rotor blades, applied on the hot wall and simultaneously conveyed towards the outlet nozzle at the opposite end of the body. The generated vapours are streaming counter-currently to the product flow and are leaving the dryer close to the feed nozzle. Evaporating and conveying capacity are adapted by the right rotor blade arrangement. Entrained particles from the dry zone are removed in the wet zone. Moisture levels of less than 1 % can be achieved. The residence time of the product is typically between 5 and 15 minutes. The outstanding heat transfer rate for hot solid products enables cooling of large amounts of solids in a compact machine compared to usually used cooling screws and without cooling air.In product melting like the melting of urea, the particles are heated up and molten inside the dryer. The melt can be mixed with other liquid and solid additives to improve the properties of the final products.
