Fully Automatic Sludge Dewatering Machine Better than Belt Filter Press
Multi-Disk Screw Press( Hereinafter referred as MDS ) belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. MDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.

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.

Q: What’s MDS Sludge Dewatering?
A: MDS Sludge Dewatering machine 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 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?
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?
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?
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.
