China Multi-Plate Screw Press Sludge Dewatering Machine - Top Suppliers and Factory for Efficient Wastewater Treatment
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.
Ideal For
The Sludge Dewatering Screw Press can be widely used for various wastewater treatment systems such as municipal, petrochemical, chemical fiber, paper making, pharmaceutical, leather and other industrial water treatment system. Also it can be used for Dairy Farm Manure Treatment, Palm Oil Sludge, Septic Sludge, etc. The practical operation shows that Dewatering Screw Press can bring considerable economic and social benefits for users.
Feature
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 Sludge Dewatering Screw Press operate?
The conditioned sludge enters the filter zones from the flocculation tank and is moved forward by the shaft. As the thread gaps narrow, the pressure rises, forcing water to separate and drain out through the gaps between the moving and fixed rings.
Which wastewater treatment applications is this machine suitable for?
It is ideal for municipal, petrochemical, chemical fiber, papermaking, pharmaceutical, leather, and other industrial wastewater treatment systems, as well as dairy farm manure, palm oil sludge, and septic sludge treatment.
Does it require a separate sludge thickening tank?
No. The screw press can directly treat sludge from aeration and sedimentation tanks, which eliminates the need for a sludge thickening tank, reduces construction costs, and prevents phosphorus release.
How does the self-cleaning mechanism prevent clogging?
The continuous relative movement between the fixed and moving rings cleans the filtration gaps automatically. This self-cleaning action prevents clogging, making it highly effective for processing oily sludge without requiring high-pressure wash water.
What are the energy and noise advantages of this machine?
It operates at a very low speed, which results in minimal noise and extremely low energy consumption—using only about 1/8 the power of a belt press and 1/20 of a centrifuge system.
Can the dewatering screw press be operated automatically?
Yes. The machine is designed with no easily-blocked elements and can be configured to operate fully automatically via the electrical control cabinet, making operation and maintenance simple and safe.
