Sludge Dehydrator

Sludge Dehydrator

Volute sludge dehydrator is a continuous screw press machine, can reduce the sedimentation tank and sludge concentration pool, saving sewage station construction costs. The use of automatic update filter cake filter technology instead of the traditional filter filter, filter their own filter filter technology to ensure continuous dehydration of the sludge separation effect, through the screw diameter and pitch changes in the strong squeeze force, As well as swimming ring and the fixed ring between the tiny gap, to achieve the sludge dewatering, is a new type of solid-liquid separation equipment.

Our Advantages of Volute Sludge Dehydrator

1. Widely used
Can be widely used in municipal sewage, food, slaughtering breeding, printing and dyeing, oil chemical industry, paper making, leather, pharmaceutical and other industries of sludge dewatering;
2.Exclusive pre-concentration design, applicable sludge concentration of 2000mg/L-50000mg/L;
3.Due to the innovation of the structure design, it is highly suitable to various high and low concentration sludge, most especially for the oily ones.

2.Clog-free
Due to rotation of helical axis, the moving rings begin detaching from the fixed rings while continuously starting the self-cleaning process. As a result, the ubiquitous clogging is avoided. Therefore, it can handle oily sludge without any trouble while separating the water from the sludge easily. In addition, there is no need to add large quantity of flushing water and there is no odor and no secondary pollution during the dewatering process.

3. Continuous automatic operation
There are no easily blocked pieces such as belt and filtration pore in Multi-Disk Screw Press. Combining with the auto control system, the machine runs very safely and simply and can be programmed according to the requirement of the users. It can operate automatically for 24 hours, unmanned.

4. Save operating costs
Multi-Disk Screw Press works by the machine’s internal pressure and needs no large scale integrations like rollers. It saves energy and water and has very minimal noise because of low running speed (2-4 r/min). The average unit power consumption is only 0.1-0.01kwh/kg-DS (1/8 of Belt Press and 1/20 of Centrifuge), and can greatly reduce the running cost of wastewater treatment system.

5. Without secondary pollution
The screw shaft rotational speed about 2-3r/min, no vibration and noise is very small ; The laminated with self - cleaning function, plugging does not occur, only a small amount of water washing, without secondary pollution, and sludge at such a slow running under the operating condition, the smell does not spread, thereby creating a great work environment!
Contactless, Wear Free Structure Design
Multi-Disk Screw Press uses the contactless wear free structure between the disks and screw shafts, thus the service life of the Screw shafts and the rings will be greatly extended. The treatment capacity of equipment and processing effects can be improved in combination with other optimization design.

6. The body is lightweight and durable
As the direct use of mechanical extrusion dehydration, no need to drum and other large body, so the machine is designed to be very light; almost all of the body using stainless steel, replacement parts only screw shaft and swimming ring, long life, durable.

7. Decrease capital investment
Multi-Disk Screw Press can treat sludge in aeration tank and secondary sedimentation tank without setting sludge thickeners. Therefore, this can decrease the total investment, avoid phosphorus release from the sludge thickeners and sludge storage tanks and enhance phosphorus removal effect of the wastewater treatment system.


8. High resistance to remove phosphorus
Promote the phosphorus removal capability Dewatering sludge under aerobic conditions, it does not occur phosphorus release, so as to enhance phosphorus removal function of the whole sewage treatment system.
