Product Description

DEWATERING SCREW PRESS 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 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 finally discharged from the end.
DEWATERING SCREW PRESS Description

Juntai Multi-Disc Sludge Dewatering Screw Press belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction.HLDS uses screws and moving rings to clean itself as a clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, and so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.

Applications:

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.

Advantages:

1. Enclosed to minimize odors and noise Very low wash water usage (1/8 compared with belt press)

2. Very low power consumption (1/20 compared with a centrifuge)
3. High cake solids
4. Minimal operator requirement
5. Easy to operate and maintain
6. Auto Start-up, Run, and Shutdown
7. Touchscreen operation optional
8. Sludge Flow and Cake Monitoring Systems

9. Available with many other options like Dairy, Palm Oil, etc.

Technology Advantages

Sludge Concentration 2000mg/L-50000mh/L
Configuration exclusive spiral plate for pre-concentration and better for treating low-concentration sludge.
1. Replacing gravity-type dehydrator to realize efficient concentration of sludge.
2. Flocculation and concentration operating together make dewatering easy.
3. Optimize the concentration of slurry for dewatering with a solenoid control valve.
Rings substitute filter cloth, self-cleaning, no clogging, easy treatment
The traditional dewatering equipment 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 cleaning so no small or secondary pollution will be produced.

The low-speed operation, low noise, low energy consumption, only 1/8 of the belt type, 1/20 of the centrifuge

Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.

Comparison Chart

Reduce the cost of infrastructure investment, improved the result of treatment

1. 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 anymore. Therefore, the construction cost can be greatly reduced and well avoided the phosphorus releasing problem.

2. Saving the cost of sludge thickening tank and other equipment investment.

3. Occupy smaller areas, and reduce construction investment for dewatering.

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.
