Multi-disc Sludge Dewatering Screw Press belongs to the screw press, its clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. The equipment using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, its a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.
Working Principles
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, Then 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 shaft and finally discharged form the end.
Technology Advantages
Configurating exclusive spiral plate for pre-concentration and better for treating low
concentration sludge.
- Replacing gravity type dehydrator to realize efficient concentration of sludge.
- Flocculation and concentration operating together makes dewatering easy.
- Optimize concentration of slurry for dewatering with solenoid control valve.
Rings substitute filter cloth, self cleaning, no clogging, easy treatment of oily sludge
The traditional dewatering equipments are easily got blocked while 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 chleaning so that no smell or secondary pollution will
Low speed operation, low energy consumption, only 1/8 of the belt type, 1/2 of the centrifuge
Reduce the cost of infrastructure investment, improve the results 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 equpments investment.
- occupy smaller area, reduce construction investment for dewatering
Fully automatic control, easy operation and maintenance
The dewatering screw press has no easy-bllocking 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.
