Efficient Sludge Screw Press Machine for Sale - China Suppliers & Factory for Wastewater Treatment Solutions
Working Principle
Screw type sludge dewatering press (Screw Press) is structured with a filter element that consists of two types of Rings: a Fixed Ring and a Moving Ring; and a screw that thrusts the filter element and transfers and pressurizes the sludge.
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 makes 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 easiest to damage system when in use. All of the parts of Juntai Screw Press sprinkler system are made by SS304, including the pipe, the injector and the nozzle, it will never need to replace the sprayer nozzle.
Detailing Guarantee Quality
Juntai focuses on every detail of the Screw Press, such as the smooth surface, the cable protection, the wire stable Radius and smooth angles, welded line and all the detailings. Juntai tries 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 is much harder than that of SS304, and with the Cobalt Alloy wear layer, the screw is harder and can be used many more years.
French Schneider Electric Control Cabinet
JUNTAI dewatering machine is installed with French Schneider electric control box, this high quality control box can better ensure the safety.
Pressure Water Gun With Fiberglass Hose make clean Easier
JUNTAI Screw Press has a pressure water Gun with high quality strengthen hose, which can clean any part of the machine easier.
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
How does the self-cleaning mechanism of the Juntai Screw Press work?
The dewatering press utilizes a filter element composed of alternating Fixed and Moving Rings. The continuous rotation of the screw shaft pushes the Moving Rings, causing them to shift and continuously clean the gaps. This automatic process prevents clogging without the need for high-pressure flushing water, making it ideal for processing oily sludge.
Can this machine handle low-concentration sludge directly?
Yes, the Juntai Screw Press is equipped with an integrated pre-thickening tank. This allows it to handle low-concentration sludge directly from aeration and secondary sedimentation tanks, eliminating the need for separate sludge thickening or storage tanks and significantly reducing infrastructure costs.
What are the power and water consumption advantages of the Juntai Screw Press?
The main screw operates at a slow speed of 2-4 rpm, consuming only 1/20 of the power of a centrifuge and 1/8 of a belt press (approx. 0.01-0.1 Kwh/kg-DS). Due to its self-cleaning mechanism, the cleaning water required is only about 1/115 of a belt press and 1/62 of a centrifuge.
Why are the screws in this machine more durable?
All screws are welded with a specialized Cobalt Alloy Wear Layer. This layer is significantly harder than standard SS304 stainless steel, protecting the screw from wear and extending the overall service life of the machine by many years.
What range of capacity and waste water types can it handle?
The treatment capacity ranges from 0.5 Kg-DS/h up to 1768 Kg-DS/h depending on the model. It is capable of processing Raw waste water, Activated Sludge Water, Chemical Precipitated Sludge, and DAF Sludge.
What industries is the Juntai Screw Press suitable for?
It is widely applied in municipal sewage, food processing, slaughtering and breeding, printing and dyeing, oil chemical industry, paper making, leather manufacturing, pharmaceuticals, and various other industrial sludge dewatering sectors.
