Low Operational Cost Sludge Thickening Equipment Advanced Wastewater Treatment

The screw body is consist of fixed rings, movable rings, screw bars, gasket and the main

screw. While working, the movable rings will move as a cycle around the main screw,

however, the gasket ensures there have some gap between the fixed ring with the movable

ring, so that avoid block to realize self-washing function, and thus greatly decrease the

consumption of washing water.

High Efficient Sludge Squeezing Technology: to greatly decrease the final cake moisture, we

adopts two special structures:

1. The screw distance is decreasing from inlet(bottom side) to outlet(top side). At the same

time, the diameter of the screw is becoming bigger from inlet to outlet.

2. On the main shaft, in the cake discharging tank, there is a baffle and there is a gap between

the baffle with the dewatering roller, so that ensure there will have some pressure to the

sludge. Thus it can perfectly squeeze out the water and realize best filtering performance.

3. Screw Induration Technology: On the surface of the screw leaf, it is processed by the

induration materials, and this ensures the hardness can be 1000 HV and the adhesive force is

bigger than 70 MPa, so its difficult to cause deformation, and can have long life-span. Four

fiter, the normal parts are cut by cutting machine or water cutting machine, and the key parts

are cut by laser to make sure the precision.

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.
