Multi-Plate Screw Press Sludge Dewatering Machine - China Suppliers & Factory for Efficient Water Treatment Solutions
Working Principle
The conditioned sludge flows into the filter zones from the flocculation tank and is pushed forward to the discharging end. With the gaps between the thread of the shaft is getting even narrower the pressure on the sludge is getting higher and higher. Than the water is separated from the sludge and flows out from the gaps between the moving rings and fixed rings. The movement of the moving rings will clean the gaps between moving and fixed rings and prevent the machine from blockage ..
The filtered sludge cakes will be pushed forward by the finally discharged from the end.

Key Features
1. Reduce the cost of infrastructure investment, improved the result of treatment.
The dewatering screw press can directly treat the sludge from the aeration tank and the sedimentation tank so that the sludge thickening tank is not needed any more.
Therefore, the construction cost can be greatly reduced and well avoided the phosphorus releasing problem.
Saving the cost of sludge thickening tank and other equipments investment.
Occupy smaller area, reduce construction investment for dewatering.
2. Low speed operation, low noise, low energy consumption, only 1/8 of the belt type, 1/20 of the centrifuge.
3. Rings substitute filter cloth, self cleaning, no clogging, easy treatment.
The dewatering screw press allows continuous operation with no clogging due to the moving of the fixed rings and moving rings cleaning it self. Therefore, it’s especially good at oily sludge with excellent performance. Moreover, it doesn’t need additional water for high-pressure cleaning so that no small or secondary pollution will be produced.
4. Fully automatic control, easy operation and maintenance.
The dewatering screw press has no easy-blocking components like filter cloth or filtration pore inside.
Its operation is safe and easy. It also can be set to operate automatically via the elec-control cabinet.
Frequently Asked Questions
How does the self-cleaning mechanism prevent clogging in the screw press?
The machine utilizes moving rings and fixed rings. The continuous movement of the moving rings cleans the gaps between them, effectively preventing clogging. This makes it ideal for handling oily sludge without requiring high-pressure backwash water.
Does this machine require a separate sludge thickening tank?
No, the dewatering screw press can directly treat sludge from the aeration and sedimentation tanks. This eliminates the need for a sludge thickening tank, significantly reducing infrastructure costs and preventing phosphorus release.
What are the energy and noise levels of the screw press compared to other systems?
The screw press operates at a low speed, resulting in low noise and exceptionally low energy consumption. It uses only about 1/8 of the energy of a belt-type press and 1/20 of a centrifuge system.
Can the dewatering screw press run automatically?
Yes, it features fully automatic control. The operation can be programmed and managed automatically via the electrical control cabinet, making it easy to operate and maintain without constant manual supervision.
What industries and applications is this dewatering machine suitable for?
It is highly suitable for municipal, petrochemical, chemical fiber, paper making, pharmaceutical, and leather wastewater. Additionally, it effectively treats agricultural and organic sludge, including dairy farm manure, palm oil sludge, and septic sludge.
