Screw Press Sludge Dewatering Machine



Screw press sludge dewatering machine is an advanced sludge dewatering equipment in the world.

Compared with the traditional belt filter press and plate and frame filter press, its unique mechanical structure gives it the advantages of small floor area, non clogging, automatic unattended operation, no need for sedimentation tank and sludge thickening tank, etc. The closed design can also greatly improve the on-site operation environment.

Screw Press Sludge Dewatering Machine


The Screw Press is widely used in papermaking, printing and dyeing, textile, food processing, beverage, municipal, sewage treatment plant, livestock wastewater treatment, Slaughter wastewater treatment and other industries of wastewater treatment.


Screw Press Treatment Process


The gaps between the Rings and the screw pitch are designed to gradually get narrower towards the direction of sludge cake outlet and the inner pressure of the filter element increases due to the volume compression effect, which thickens and dewaters the sludge.

Screw press sludge dewatering machine working principle


1.Treatment of low concentration sludge

It is recommended that the sludge concentration be between 2000mg / L and 50000mg / L

The screw sludge dewatering machine configurates exclusive spiral plate for pre-concentration and better for dealing with low concentration sludge.To improve the shortcomings of gravity type in order to realize efficient concentration of sludge.

Floucculation and concentration operating together,make dewatering easy.Optimize concentration of original sludge for dewatering with intelligent control valve.

2.Self cleaning, no blocking

Movable and fixed ring instead of filter cloth, self-cleaning, no blockage, easy to treat oily sludge

Fixed plate substituted filter, self cleaning,no clogging, easy treatment of oily sludge.There is an automatic cleaning nozzle above the screw shaft, which can be set by PLC and equipped with a high-pressure water gun.

3.Low noise, low energy consumption

Energy saving and emission reduction to reduce noise pollution.

The screw sludge dewatering machine depends on the volume pressure dehydration, dispensing with drums and other large-sized devices so as to realize a low operation speed, which is only 2-4 revolutions per minute.
