Sludge Dewatering System
Sludge drained from the primary or secondary clarifier is collected in a sludge holding tank and is conditioned by adding PE (Poly-electrolyte). The conditioned sludge is then passed through plate type filters press for sludge dewatering and drying. The complete dewatering unit consist of sludge thickening tank, PE dozing unit, screw type sludge lift pump & filter press. The process of dewatering is taken place under pressure which help separting liquid from solid contents & make cakes of sludge on filter cloths provided with filter press plates. The wet sludge having moisture contents less than 30% can be disposed in cakes. The activated sludge can be used as manure in plantation.
Before a new plant is under operation, it is necessary that all operation and maintenance personnel understand the function and location of each process unit, mechanical equipment and piping.
