Screw Press Sludge Dewatering Machine Waste Water Treatment for Sewage Treatment Plant

Clog Free Sludge Dewatering Press (MDS 312) Clog Free Sludge Dewatering Press, BENENV's MDS dewatering press is a unique dewatering machine. It offers below advantages over traditional sludge dewatering press: 1. Power Saving, the power of biggest model of MDS sludge dewatering press is just 6kw2. Low Cost and running cost, due to low rpm, the wearing is very small so the spares have long service life3. Low labor work, unattended operation and a general worker can operate machine well4. Low noise, only 2-3 RPM5. Clog-free, MDS sludge dewatering press is of fixed ring and moving ring combination screw press. The moving rings clean the filter gap during dewatering operationIn a word, if you are tired of centrifuge's annoying noise and huge power consumption, or if you are tired of belt press and filter press clog issue and large footprint, you should come to us. Our MDS sludge dewatering press can help to solve your problems.Japanese Technology, Japanese Quality Control, Competitive Price BENENV is a company with over 40 years of experience in the sludge treatment on design, engineering, manufacturing and installation. We focus on the dewatering treatment (first & second dewatering, biological aerobic drying) and resource utilization of sludge from wastewater of all industries. Our products line includes Multi-disk screw press series (MDS), KDS thickening and dewatering series, electric osmosis equipment, sludge drying machine and sludge incinerator.Benenv are always focusing on independent technology innovation of themselves. We have our own Japanese branch company "Japan Benenv Co., Ltd.", which is technology research and design center and also help headquarters to do the Japanese Quality Control. Benenv have already got international qualifications as ISO9001: 2008 and CE marks for all products, national awards as Utility Model Patent for MDS series and KDS, sludge drier, etc, and High-tech Enterprises Qualification, etc. products are mostly exported to the European and North American countries. BENENV are also working closely with top 10 universities and government organizations in China and Japan such as Tokyo Industry University and Nanjing Agriculture University to keep our technology of cutting-edge and transform science and technology into productivity. Structure of Sludge Dewatering PressMDS is a new generation of sludge dewatering technology -BENENV® multi-disk screw press, a screw type sludge dehydrator that is much more advanced in very aspects than belt presses, Centrifuges, plate-and-frame filter presses, etc. It features clogging-free, wide range of applications, low energy consumption, simple operation & maintenance.Process of Sludge Dewatering PressMDS has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines, plate-and-frame filter press have, which are frequent clogging, low concentration sludge / oil sludge treatment failure, high energy consumption and complicated operation etc.Sludge Overflow: Sludge is pumped into the dehydrator inlet tank, and from there, it flows over a triangular overflow discharge into the flocculation tank. Sludge quantities exceeding the equipment capacity, are returned through the safety overflow.Flocculation: The flocculation tank is stirred with a low-speed paddle mixer, and the polymeric flocculent is dosed into the incoming sludge. The flocculent solution is prepared directly at the wastewater treatment plant, by mixing the concentrated reagent with water, in an independent tank. It is then dosed in sufficient quantities by a dosing pump. The reaction of the flocculent with the sludge, causes clearly defined flakes to be formed in the dehydrator flocculation tank and subsequently brought into the thickening and dewatering drum.Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank by gravity.Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produced.Applications of Sludge Dewatering PressSpecial pre-concentrating device, no need thickening equipment, widely feed low solids concentration , can be Widely Used in different applications:Exclusive pre-concentration design, applicable sludge concentration of 2000mg/L-50000mg/L; 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.l  Municipal water and wastewater treatment plantsl  Agricultural/fishery community wastewater treatment plantsl  Industrial waste treatment plantsl  Food/beverage production
