Sewage Treatment Plant for Industrial Wastewater Treatment Companies (MDS311)(1) BENENV's sludge dewatering machine is of unique dewatering structure with fixed and moving rings. It has many advantages over other dewatering machines such as plate and frame filter press, belt filter press and decanter centrifuge, especially for power and rinsing water consumption and labor cost saving. Below is a comparison table among them.
(1) High resistence to oily sludge
The self-cleaning mechanism and stainless steel structure enables MDS to be ideal to dewater oily sludge, which easily cause clogging and is difficult to treat with other types of dewatering equipment like belt filter press.
(2) Clog-free -- saving rinsing water -- saving cost
Due to the 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 with the unique structure. 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 rinsing water, thus MDS can saving the cost.
(3) Saving energy -- low power consumption
MDS 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 0.1-0.01 kwh/kg-Ds (1/8 of Belt Press and 1/20 of Centrifuge).
(4) Fully automatic control -- saving labor cost
There are no easily blocked pieces such as belt and filtration pore in MDS. 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.
(5) Small footprint -- saving the construction investment of dewatering room
With the smart design, MDS dewatering press can be installed in places where placement would not be possible with other technologies.
(6) No thickeners -- saving the capital investment and costs on other auxiliary equipment
MDS can treat sludge in aeration tank and secondary sedimentation tank without setting sludge thickeners. Therefore, this can decrease the total investment and costs on mixers, air compressors, flushing pumps and other auxiliary equipment.
Sewage Treatment Plant for Industrial Wastewater Treatment Companies (MDS311)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.

Packing & Delivery
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.
