Best Quality Screw Filter For Wastewater Treatment
Structure of Screw Filter
The screw filter press consists of fixed rings, moving rings and screws. The front part is for thickening; the rear part is for dewatering. The filtering space between the fixed ring with the moving ring, the screw pitch are becoming more and more small from the front part to the rear part. The screw pushes the slurry forward, and at the same time, the screw will move around orbicular to avoid blocks. We are professional screw filter press manufacturer.
Working Steps of Screw Filter:
1.Flocculating:
The waste water will flow into the mixing tank with flocculant. Then the solid will flocculate to big particles.
2.Dewatering:
The flocculated waste water will flow into the screws. The clean free water will discharged through the gaps between the rings, however, the solids are blocked and deposit. With the movement of screw, the solids are transported to the outlet.At the same time the screw pitch is going to smaller, thus to squeeze the solids, so that finish the dewatering function.
3.Cake Discharge
The filter cakes are pushed out by the screw to discharge cakes.
4. Self Washing:
With the continuous rotation of screws, the rings are driven to move circular. And the water will spray the external side of the rings to refresh the filtering performance avoiding block.
Features of Screw Filter:
- 24 hour contentiously work.
- Big capacity.
- Good filtering performance.
- Stainless steel structure with long life-span.
- Also suitable for lower solid content wastewater (2000 mg/l ~ ).
- Compact design.
- The machine integrated with the cabinet, mixing tank, and the dewatering part.
- Easy maintenance and light weight.
- Self washing function.
- Especially suitable for wastewater having oil.
- Low moving speed (2~3 r/m), low power consumption.
- Stable performance, quite working and safety operation.
- Less spare parts (only the screws and the moving ring) and can use long time.
