China Multi-plate Screw Press Sludge Dewatering Machine - Factory Suppliers 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.
Ideal For
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 separate water from sludge?
The conditioned sludge flows from the flocculation tank into the filter zones. As it is pushed forward, the gaps between the shaft threads narrow, increasing the pressure and forcing water to separate and drain out through the gaps between the moving and fixed rings.
What applications is this dewatering machine suitable for?
It is highly suitable for municipal and industrial wastewater systems (such as chemical, paper, pharmaceutical, and leather) as well as specialized tasks like dairy farm manure, palm oil sludge, and septic sludge treatment.
How does the machine help in reducing infrastructure costs?
By directly treating sludge from the aeration and sedimentation tanks, it eliminates the need for a sludge thickening tank. This lowers construction expenses, saves space, and prevents phosphorus release.
Does the screw press clog when handling oily sludge?
No. The continuous relative movement between the fixed and moving rings provides a self-cleaning mechanism that prevents clogging, making it highly efficient for oily sludge without requiring high-pressure cleaning water.
Is the operation of the dewatering screw press automated?
Yes, the machine supports fully automatic operation controlled via an electrical control cabinet, making it easy to manage and maintain without risk of blockages.
