Product Details
Steel Cover and PMMA Windows make safer
Stainless steel Cover with two handles on the above of the main body, Glass windows in both, The cover make the equipment safer and the worker safer when running. In addition, the steel plate cover can effectively prevent dust from falling in and affecting the service life.
Steel Sprinkler System got longer life
The Sprinkler system is very important to the dewatering system, it is the most easy to damage system when use. All of the parts of Juntai Screw Press sprinkler system are made by SS304, including the pipe, the inject and the nozzle, it will never need replace the sprayer nozzle.
Detailing Guarantee Quality
Juntai focus on every detailing of the Screw Press, such as the smooth surface, the cable protect, the wire stable Radius and smooth angles, welded line and all the detailings, Juntai try to do as best as we can, and this is also a way to ensure the quality.
Cobalt Alloy Wear Layer Make Screws Harder
All of Screws of Juntai Dewatering machine are welded a Cobalt Alloy Wear layer which are much harder than that of SS304, and with the Cobalt Alloy wear layer, the screw is harder and can be used many more years.

JUNTAI Screw Press Technology Advantage
JUNTAI Technology Advantage 1
Equipped with pre-thickening tank and better at dealing with low concentration sludge. Improved gravity thickening shortcomings and realized high efficient thickening. Flocculation and thickening are integrated, dewater becomes easier. Combine with regulating end plate, sludge concentration can be optimized.
JUNTAI Technology Advantage 2
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.
JUNTAI Technology Advantage 3
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.
JUNTAI Technology Advantage 4
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.
JUNTAI Technology Advantage 5
Fully automatic control, simple operation and management. Screw press doesn't have any components like filter cloth or filter pore which are easily clogged. The operation is safe and easy. The machine also can be operated automatically by control cabinet.
JUNTAI Technology Advantage 6
Wide range of application. Can be widely used in municipal sewage, food, slaughtering breeding, printing and dyeing, oil chemical industry, paper making, leather, pharmaceutical and other industrial of sludge dewatering.

Frequently Asked Questions (FAQ)
What is the working principle of the Juntai Screw Press?
The Screw type sludge dewatering press uses a filter element structured with alternating Fixed Rings and Moving Rings. A central screw thrusts through this filter element to transfer and pressurize the sludge, effectively separating water from the solids.
How does the self-cleaning mechanism prevent clogging?
As the screw shaft rotates, it continuously pushes the Moving rings to detach from the Fixed rings. This movement generates a continuous, automatic self-cleaning process that prevents clogging without relying on high-pressure flushing water. It is highly effective even for oily sludge.
What makes the screws and sprinkler system durable?
All screws are welded with a Cobalt Alloy Wear layer that is significantly harder than standard SS304, extending the machine's lifespan. Additionally, the entire sprinkler system—including the pipes, injectors, and nozzles—is built from high-grade SS304.
How energy and water-efficient is the Juntai Screw Press?
The screw rotates slowly at 2-4rpm, resulting in low power consumption (0.01-0.1 Kwh/kg-DS), which is 1/20 of a centrifuge and 1/8 of a belt press. The self-cleaning filter mesh also reduces water usage to approximately 1/115 of a belt press and 1/62 of a centrifuge.
Can it handle low-concentration sludge directly?
Yes. Because it is equipped with an integrated pre-thickening tank, it can directly treat sludge from aeration and secondary sedimentation tanks. This eliminates the need for standalone sludge thickening or storage tanks, reducing infrastructure costs.
What are the capacity ranges and application scopes?
The capacity ranges from 0.5 Kg-DS/h to 1320-1768 Kg-DS/h. It treats raw wastewater, activated sludge, chemical precipitated sludge, and DAF sludge across industries like municipal sewage, food processing, oil chemical, paper making, leather, and pharmaceuticals.
