Beschreibung
Zusammenfassung:	The invention relates to a process for dewatering sewage sludges using plate filters, wherein the flocculated sewage sludge treated by means of organic polymer flocculation aids and optionally other auxiliary agents is separated from the major amount of water of the flocculated sewage sludge on a plate filter by means of hydrostatic filtration, whereafter the partially dewatered sewage sludge is subjected to pressure filtration. The plate filters employed have filtrate outlet systems permitting filtrate discharge at a flow rate of 1.0 m/s at maximum. By conducting the process in this way, the dewatering capacity is substantially increased.
