Wastewater Screw Press

24 hours fully automatic operation.

No clogging, reducing flushing water consumption.

Suitable for various kinds of sludge dewatering.

Higher dehydration efficiency than traditional equipment.

Low power consumption, basically no vibration and noise on site.

The Sludge Screw Press is composed of main body, driving device, filtrate tank, mixing system, frame body, etc.
When it is working, the sludge is lifted to the mixing tank by the sludge pump. At this time, the dosing pump also quantitatively transports the liquid to the mixing tank, and the stirring motor drives the entire mixing system to combine the sludge with the liquid. This way could fully flocculate the material. When the liquid reaches the upper level of the liquid level sensor, it will send a signal to make the sludge screw press work. Under the action of the screw shaft, the sludge is lifted to the sludge outlet gradually, and the filtrate flows out from the gap between the fixed ring and the moving ring. The inner cavity formed by the screw shaft and the ring sheet is filled with flocculated particles, which are conveyed and squeezed to create a mud cake during the rotation of the end back pressure plate. The screw shaft rotates and pushes and continuously drives the movement of the moving ring up and down, left and right to clean the filter slits to prevent clogging.
