Flow Diagram:

1.The sludge in the sludge sump is carried to the measuring tank by sludge pump.And the

sludge inlet volume can be controlled by adjusting the liquid level tube.

2. Sludge and flocculant will form alum floc in the disposal tank after agitator mixing, the ideal

diameter of alum floc is about 5mm.

3. After gravity thickening in the thickening part, large amount of filtrate will discharge from

the gaps between rings.

4. The thickened sludge is carried forward by the screw and dehydrated sufficiently under

the pressure of the back pressure plate.

5. The dehydrated mud cake is discharged from the gaps between back pressure plates and

screw body. The treating capacity of sludge and water content's rate of mud cake can be

controlled by adjusting the running speed of screw and gaps between back pressure plates.

Technical parameters

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.
