Sludge dewatering introduction
The sludge dewatering press is an enclosed high performance sludge dewatering system. It utilizes a central screw auger and a slowly oscillating multi-disk filter to gradually increase pressure on flocculated sludge to produce an exceptionally dry sludge cake. With electrical, water and polymer usage, and high capture rates the system is very cost effective.
The sludge dewatering press can be provided with all equipment required for sludge dewatering included and factory mounted, piped and wired on a single stainless steel skid. This equipment includes the sludge pump, wash water pump, polymer dosing system and control panel. The system features fully automated one pushbutton startup and shutdown. Once started up the system can run unattended and can be set to shutdown automatically with no operator intervention.
volute sludge dewatering press structure principle
The main part of the dehydrator is a volute sludge dewatering press that a screw runs through the stacked fixed rings and moving ring.
The small gaps between fixed rings and moving ring can filter the sludge, and the lumen between screw and rings is filled with polymer grains. The moving ring transfers the sludge to the end of the machine with pressure and extrudes sludge cakes.
Layers of the spacers, which are fixed and moving rings, are secured in place by a tie rod. The inner diameters of the moving rings are slightly smaller than the outer diameter of the screw and their rings. Mobilized by the screw, it continuously cleans the sludge out of the gaps, therefore, preventing clogging.
The running of the volute sludge dewatering press the moving ring to clean the gaps and avoid jam.

1. Force-water cocurrent. Force and water are in the same direction, making the free water comes out at the fastest speed. 2. Extension of deatering path. Not only ensuring the amount of time during the process of sludge dewatering, but also ensuring the continuous operation. 3. Moderate pressure. Maintain lowest energy consumption and mechanical wear while ensuring the sludge dewatering effect. 4. Thin-layer dewatering. Thinning the sludge to make the free water come out by going a shorest distance. |
