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.
