Procedure of dewatering machine

1. The sludge are transported to the flocculation tank through storage tank, and adequately

mixed by the mixer.

2. After big flocs are formed, the sewage is transported to the MDS screw press.

3. Flocs moves from the thickening zone to the dewatering zone.

4. Gaps between moving rings and fixed rings narrows, and the pressure of the end plate

increases dewatering,finally the sludge cake is discharged.

5. The sludge is transported out by shaftless screw conveyor.

Advantage

1. One-in-all design, fits in small facility

Multi-plate Screw Press adopted the unified structure that serves two functions, thickening

and dewatering in the single machinery. The drum filter, because of the clog-free, realizes

higher speed of filtering phenomena per filtering area as compared to other methods. For this

reason, low concentration sludge of about Total Solids 0.2%, as well as thickened sludge, can

be directly fed without pre-thickening.

2. Wide range of line-up/Small footprint

The model of sludge dewatering press based on the customer needs can be selected from a

wide range of line-up, and can be installed in places where placement would not be possible

with other technologies for reasons such as low building ceilings or limited area. This makes

Multi-plate Screw Press suitable to customers who are considering the replacement of existing

dewatering equipment.

3. Easy operation/Easy maintenance

Full automatic 24-hour operation without an operator on-site is possible with automatic

operation control using various sensors. With this function, manual operation, such as starting

or stopping, is not required. Moreover, daily maintenance is minimized, requires no skilled

labor neither special knowledge, so that everybody can use it easily.

4. Power and water saving

The screw which is the main component rotates very slowly at a rate of 2 to 4 rpm, so that it

consumes very low power and thus economical. Multi-plate Screw Press prevents filter mesh

from clogging with its unique self-cleaning mechanism, removing the need for huge amounts

of water for clogging prevention.
