Effluent Water Treatment Products Multi-Disk Screw Press Sludge Handling System

Slurry filtering is composed of screw body, driving device, filtrate receiver, mixing system and frame. When the volute dewatering press operation, sludge will be transported to the mixing tank by sludge feed pump, at the same time, the solid polymer has been added to the mixing tank quantitatively by the polymer feed pump. Mixing motor drives the whole mixing system to make the sludge and polymer fully mixed and then flocs will be produced. When the liquid level arrives at the superior level of the liquid level sensor, the liquid level sensor gets the signal to make the motor of screw body operates, then begins to press the sludge which has flows into the screw body. Sludge will be transported to the outlet step by step by the effect of screw shaft; filtrate will flow out by the space of fixed rings and moveable rings.

The main body of press filter sludge dewatering machine is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is concentrating section and the ending part is dewatering section. It can concentrate and dewater sludge in one chamber. Sludge will be transported to the dewatering part after being concentrated in the thickening section. In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance with the block of the back platen. Then the volume decreases continuously, and the purpose of fully dewatering will be achieved.

The sludge dewatering screw press can be widely used for dewatering sludge of municipal administration wastewater, food, beverage, drink, slaughtering and breeding, printing, petrochemical engineering, papermaking, tannery and pharmaceutical.
