China Multi-plate Screw Press Sludge Dewatering Machine - Reliable Suppliers & 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
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 itself. 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
Q: How does the Sludge Dewatering Screw Press prevent clogging?
The continuous movement of the fixed and moving rings automatically cleans the filtration gaps, preventing blockage without requiring high-pressure cleaning water.
Q: What types of wastewater and sludge can this machine treat?
It is ideal for municipal, petrochemical, chemical fiber, paper making, pharmaceutical, leather, and other industrial wastewater treatment systems. It is also suitable for dairy farm manure, palm oil sludge, and septic sludge.
Q: How does the screw press reduce infrastructure investment costs?
It directly treats sludge from aeration and sedimentation tanks, eliminating the need for a sludge thickening tank. This reduces construction costs, saves equipment investment, occupies less area, and avoids phosphorus release issues.
Q: What are the energy and noise advantages of this machine?
The machine operates at a low speed, producing low noise and minimal energy consumption. Its energy usage is only 1/8 of a belt-type press and 1/20 of a centrifuge.
Q: Can the Dewatering Screw Press run automatically?
Yes, the system features fully automatic control via an electric-control cabinet, ensuring safe, easy operation, and simplified maintenance.
