Fixed and Moving rings replace filter cloth.
The rotation of screw shaft pushes the detaching of Moving rings from Fixed rings, which brings self-cleaning process continuously and automatically. This enables stable and constant dewatering to take place without depending on high pressure flushing water to prevent clogging. This also enables being ideal for oily sludge, which easily causes clogging and is difficult to treat with other types of dewatering equipment.

Low noise, low vibration, power saving, water saving.
As the main component, the screw rotates very slow at a rate of 2-4rpm, no need large integration like rollers, so that it consumes very low power and thus environment friendly. The power consumption of screw press is 1/20 of centrifuge which requires rotation at high speed, 1/8 of belt press, which is only 0.01-0.1 Kwh/kg-DS. Its unique self-cleaning mechanism prevents filter mesh from clogging, then no need for huge amounts of water for clogging prevention. The amount of cleaning water required is about 1/115 of belt press and 1/62 of centrifuge.

Reduce infrastructure investment cost, improve treatment effect.
Screw press can directly treat the sludge from aeration tank and second sedimentation tank so no need sludge thickening and sludge storage tank. The infrastructure investment can be greatly saved and the phosphorous release problem is well avoided. Thus the sewage treatment system dephosphorization can be enhanced. Save infrastructure investment also on mixer, air compressor, washing pump and other related corollary equipment. Less footprint occupy, less dewatering plant infrastructure investment.

Frequently Asked Questions (FAQ)
Q: How does the self-cleaning mechanism in the Screw Press work?
The filter cylinder consists of alternate Fixed and Moving rings. As the screw shaft rotates, it continuously pushes and moves the moving rings relative to the fixed rings, creating an automatic self-cleaning action that prevents clogging without the need for excessive high-pressure flushing water.
Q: Can JUNTAI Screw Press handle oily sludge?
Yes. Because the moving rings detach from the fixed rings during screw rotation to continuously clean the filter pores, oily sludge that typically blinds standard filter cloth or centrifuge screens can be dewatered without clogging.
Q: Why is the screw shaft more durable than standard stainless steel?
All screws in the JUNTAI dewatering machine are welded with a Cobalt Alloy Wear layer, which possesses significantly higher hardness and abrasion resistance compared to standard SS304, extending the working lifespan by years.
Q: How much energy and water does the Screw Press save compared to other systems?
The screw rotates at only 2–4 rpm, consuming approximately 1/20 of the electricity of a centrifuge and 1/8 of a belt press (0.01–0.1 Kwh/kg-DS). The water consumption required for flushing is approximately 1/115 of a belt filter press and 1/62 of a centrifuge.
Q: Can it directly process low-concentration sludge from aeration tanks?
Yes. JUNTAI Screw Press is equipped with an integrated pre-thickening tank that combines flocculation and thickening, allowing it to directly process sludge from aeration and secondary sedimentation tanks without requiring dedicated sludge thickening and storage tanks.
Q: What industries are suitable for this dewatering equipment?
It is suitable for municipal sewage, food processing, slaughterhouses, breeding farms, printing and dyeing, petrochemicals, paper making, leather manufacturing, pharmaceutical plants, and various other industrial sludge dewatering operations.
