Description

Automatic Sludge Dewatering Belt filter press For Etp Sludge In Wastewater Treatment

The DAGYEE Automatic Sludge Dewatering Belt Filter Press is a high-efficiency, continuous solid-liquid separation solution specifically engineered for Sludge dewatering in Effluent Treatment Plants (ETP). Integrating an advanced automatic control system, precise belt tensioning and tracking technology, and multi-stage pressure dewatering zones, it ensures consistent and stable conversion of liquid sludge into solid cake with low moisture content without manual intervention, significantly reducing sludge disposal costs and environmental impact.

How belt filter presses work

Chemical Conditioning & Gravity Drainage: The sludge, after polymer flocculation, is evenly distributed on the moving filter belt, where free water is separated by natural gravity penetration.
Wedge Pre-Pressing: The sludge enters a gradually narrowing wedge zone, subjected to gentle squeezing to release more water and form a preliminary sludge layer.
High-Pressure Shear Squeezing: The sludge is sandwiched between upper and lower filter belts and passes through a series of press rollers with decreasing diameters. It undergoes progressively increasing linear pressure and shear force to remove capillary water deeply.
Cake Discharge & Belt Cleaning: The dewatered cake is scraped off by doctor blades, and the filter belts are thoroughly cleaned by a high-pressure washing system, ready for the next cycle.

Belt filter presses Advantage

BEARING FRAME Made of two very thick carbon steel plates (on request, SST), fixed to each other by means of profiles and welded to form a stiffen perfectly levelled unit. The whole structure is protected by sand-blasting type Sa 2.5, then by a zinc-aluminium alloy hot spraying and finally covered by a layer of bicomponent polyurethanic resin. Bolts and nuts are made of SST A2 AISI 304. (Ref. A)

ROLLERS The pressing, tensioning, transmission and sludge discharge rollers are protected by a layer of 8mm of rubber. The motorized pressing roller and the trajectory correction one are coated by 8 mm. of rectified rubber layer. All the rollers are supported by ball bearings type ‘Y’ which are suitably sized and guarantee a perfect impermeability. (Ref. B

BELTS TRACTION SYSTEM Models with belts width of 800, 1200, 2000 mm.: it consists of a worm motor variator with speed manual adjustment, directly keyed to the roller; Models with belts width of 1600, 2500, 2600, 3000 mm.: it consists of an epicyclic motor variator connected to a traction roller by a toothed crown and chains protected by carters. (Ref. C)

BELTS GUIDE SYSTEM Pneumatic type with proportional action probes to keep the belts continuously centered and one upon the other. (Ref. D)

BELTS TENSION SYSTEM It consists of pneumatic jacks with air springs which keep the belts tensioned. (Ref. E)

BELTS WASHING SYSTEM It consists of spray header pipes equipped with nozzles which can be cleaned by a specia plan (Ref. F)
