Screw Press Dewatering Machine Sludge Drying Machine For Wastewater Treatment
Sludge dewatering is the practice of minimizing waste by volume to prepare for its effective disposal. Sludge originates during the process of treating wastewater before the water can be released back into the environment. Long presenting a challenge for the water treatment industry, sludge is the by-product extracted from the slurry during the process of industrial or municipal wastewater treatment. Dewatering the sludge with a dewatering filter press significantly reduces its weight and its volume before disposal.
Process of Sludge Dewatering Press
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.
Applications of Sludge Dewatering Press
1-Low energy consumption.
2-Minimal water consumption.
3-Minimal noise.
4-Low polymer consumption.
5-No need for proceeding sludge thickening.
6-Suitable for any type of sludge even suitable for dewatering oil/grease rich sludge.
7-Minimal maintenance and operational cost.
8-Capable for working 24/7.

Advantages of Sludge Dewatering Press
Since MDS dewatering press 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 replace filter cloths, self-cleaning, clog-free
As MDS 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 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 .
Full-automatic control, simple operation and management
There are no easily blocked pieces such as belt and filtration pore in Multi-Disk Screw Press. 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.
