Detailed Product Description:

Sludge dewatering machine for food plant wastewater treatment


Sludge dewatering machine for food plant wastewater treatment , the clogging of filter mesh decreases the efficiency of conventional dewatering equipment. Such like belt press and filter press. BENENV\'s Sludge dewatering machine for food plant wastewater treatment is equipped with unique dewatering technology, which enables dewatering while automatically self-cleaning the filter mesh. This enables stable and constant dewatering to take place without depending on high pressure backwash water to prevent clogging. This self-cleaning mechanism enables Sludge dewatering machine for food plant wastewater treatment to be ideal to dewater oily sludge, which easily causes clogging and is difficult to treat with other types of dewatering equipment.




Japanese Technology, Japanese Quality Control, Competitive Price


BENENV are 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.

Product Description of sludge dewatering machine

MDS 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.


Sludge Treatment Process of sludge dewatering machine

MDS 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.

Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment.



BENENV constantly focus on innovation & improvements of our products to meet the requirements of the market and provide our customers with products of reliability and high performance. So far, we\'ve got dozens of patents and varieties of pending technologies on sludge treatment equipment.

What benefit you can get?

Since Sludge dewatering machine for food plant wastewater treatment can be used directly to concentrate and dewater the low-solid sludge from aeration tanks or secondary clarifiers, the users don\'t have to build a thickening tank or a storage tank any more while they have to when using other types of sludge dehydrators, especially the belt filter presses. Then significant civil engineering cost and floor area are saved.

Furthermore, the phosphorus emission problem caused by aeration tanks or secondary clarifiers can be well prevented.


Fixed/moving rings replacing filter cloths, self-cleaning, clogging-free

As MDS sludge dewatering machine using fixed rings and moving rings as filter media instead of filter cloths makes it especially good at treating oily sludge when compared with other types similar sludge dehydrator. The moving rings rotate up and down to the fixed rings when the gaps between them are cleaned to prevent from clogging.

Low-speed rotating, low noise, low energy consumption - only 1/10 of belt filter presses and 1/20 of centrifuges

MDS sludge dewatering machine doesn\'t need any big supporting equipment such as rollers to work with. The rotating speed is as low as only 2-4 r/min. As a result, it can realize water-saving, energy saving and low noise. The average energy consumption is only 0.01-0.1kwh/kg-DS, only 1/10 as that of belt filter presses and 1/20 as that of centrifuges .
