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.
