Introduction
With ISO9000 & CE certificate, the Multi-disk Screw Press developed by Benenv follows the dewatering principles of force-water current, thin-layer dewatering, moderate pressure and extension of the sludge dewatering path. It is able to treat low concentration sludge and oily sludge effectively, with low energy consumption and easy operation. This Multi-plate Screw Press realizes an energy-efficiently sludge dewatering.

Advantages
1. One-in-all design, fits in small facility
Multi-Disk Screw Press adopted the unified structure that serves two functions, thickening and dewatering in the single machinery. The drum filter, because of the clog-free, realizes higher speed of filtering phenomena per filtering area as compared to other methods. For this reason, low concentration sludge of about Total Solids 0.2%, as well as thickened sludge, can be directly fed without pre-thickening.
2. Applicable to sludge in various kinds of applications
1) Municipal water and wastewater treatment
2) Agricultural/fishery community wastewater treatment
3) Industrial waste treatment
4) Food/beverage production waste treatment
5) Dairy farming/Meat processing wastewater treatment
6) Chemicals manufacturing wastewater treatment
7) Machinery manufacturing/Metal processing wastewater treatment
8) Laundry wastewater treatmen
9) Other wastewater treatment (paper manufacturing, building material manufacturing, oilfield associated water accompanied with crude oil mining, etc.)
3. Wide range of line-up/Small footprint
The model of sludge dewatering press based on the customer needs can be selected from a wide range of line-up, and can be installed in places where placement would not be possible with other technologies for reasons such as low building ceilings or limited area. This makes Multi-Disk Screw Press suitable to customers who are considering the replacement of existing dewatering equipment.
4. Easy operation/Easy maintenance
Full automatic 24-hour operation without an operator on-site is possible with automatic operation control using various sensors. With this function, manual operation, such as starting or stopping, is not required. Moreover, daily maintenance is minimized, requires no skilled labor neither special knowledge, so that everybody can use it easily.
5. Power and water saving
The screw which is the main component rotates very slowly at a rate of 2 to 4 rpm, so that it consumes very low power and thus economical. Multi-Disk Screw Press prevents filter mesh from clogging with its unique self-cleaning mechanism, removing the need for huge amounts of water for clogging prevention.

Functional Principle
Layers of spacers, fixed and moving rings construct the dewatering cylinder. Moving rings, which are slightly smaller than the outer diameter of the screw and slightly narrower than the spacers, are located between the fixed rings. Edge of the screw pushes these moving rings in continuous circular motion.
The moving rings continuously clean sludge out of the gaps, prevents clogging and reduces the use of rinsing water.
Dewater Principle
The initial section of dewatering drum is the Thickening Zone,where the solid-liquid separating process takes place and where the filtrate will also be discharged. The pitch of the screw and the gaps between the rings decrease at the end of dewatering drum, hence increasing its internal pressure. At the end, the End Plate further increases the pressure, so as to discharge dry sludge cake.The initial section of dewatering drum is the Thickening Zone,where the solid-liquid separating process takes place and where the filtrate will also be discharged.

FAQ
Q: What's MDS Sludge Dewatering Machine?
A: MDS Japanese quality 24hrs automatic oil sludge treatment equipment has been used in Japan market for over 30 years, is a mature technology. It was developed in our Japanese research center (Japan Benenv Co., Ltd.). We have Japanese engineers for technical support and quality control, other Chinese manufacturers they are just copy-cats from this Japanese technology, they are not original and lack of experience on this technology.
Q: What type of sludge is MDS Sludge Dewatering Machine applicable to?
A: It is applicable to various kinds of sludge such as waste activated sludge, dissolved-air floatation sludge and so forth. The thickening mechanism of this equipment enables dewater not only highly-concentrated sludge but also low-concentrated sludge with ease.
Q: What's the application scope of MDS Sludge Dewatering Machine?
A: It is widely applied in Municipal water and wastewater treatment plants, Agricultural/fishery community wastewater treatment plants, Industrial waste treatment plants, Food/beverage production plants, Dairy farming/Meat processing plants, Chemicals manufacturing plants, Machinery manufacturing/Metal processing plants, Paper manufacturing, building material manufacturing, oilfield associated water accompanied with crude oil mining, etc..
Q: What's the material of MDS Sludge Dewatering Machine?
A: It is Stainless Steel, we choose SUS304H, SUS316L, etc, some key parts we import from Japan, we also have our own workshop in Japan for production.
Q: What's the equipment used together with MDS Sludge Dewatering Machine?
A: Sludge pump, polymer dosing pump, washing pump, air compressor.
Q: Why aren't your rings carbonized like other companies'?
A: Carbonization is to harden and strengthen the metal surface. Our rings material is called 304 hardened steel (SUS304H), which is directly treated by our steel supplier, this hardened stainless steel can make the hardness of carbonized steel up to HV380-420 in China. Most of other manufacturers can reach to only HV250. This hardened steel SUS304H is 3 times expensive than normal SUS304, so other manufacturers they prefer to choose the normal material and need to increase the thickness of rings in order to increase the hardness, actually, increase the thickness of rings will
affect the dewatering effects.
Q: How to choose the right model?
A: Advise us the sludge source, treating capacity, solid content rate, then we could choose the suitable model for you. Please put forward if you have special requirements.
