dewatering filter press

sludge dewatering filter press -Introduction

Multi-Disk Screw Press ( Hereinafter referred as MDS ) belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. MDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.

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.
4. Flocs moves from the thickening zone to the dewatering zone.
5. 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.
Specification Model
Detailed Images

Name: Over All Unit

Materials: SUS304 

The over all unit is made up of SUS304 material, with smooth surface. Laser cutting technical ensures the evenness of machine surface.

Name: Rings
Materials: SUS304
First of all, mechanical shaping is done to the rings by imported processing equipment from Switzerland. Then manual shaping is done to control the deviation of evenness under 0.01mm.

Name: Screw Shaft
Materials: SUS304
Tungsten carbide coating are done to the screw shaft surface. The hardness can reach HRC 71. The blade of screw shaft also get chamfering process treatment, to match with the ring.

Name: Spray Tube and Nozzle
Materials: SUS304
Spray tube uses SS304 steel, mirror polished.

Its nozzles can achieve well-distributed spray, can achieve solid cone effect,which is better than stainless steel nozzle suppliers
