Screw Press Sludge Dewatering Machine for Textile Sewage

Working Principle

The dewatering process begin at the initial section called Thickening zone, when the screw shaft rotating and separating liquid from solid sludge by the gaps between the multi-disc rings. The filtrated will then be discharge at the bottom drain hole while sludge will moving on to Dewatering zone where the pitch of the screw and the gaps between the multi-rings decrease at the end of drum, thus increasing internal pressure at the end plate to discharge dry sludge cake. 
The structure of Fixed and Moving rings provided a clog free feature in which the Moving rings are mobilizing by the screw and continuously cleans the sludge out of the gaps to prevent clogging.  

Advantages

1. Widely used in many industries sludge treatment including municipal sewage, food, slaughtering breeding, printing, dyeing, oil chemical, paper industry, leather, pharmaceutical, etc.

2. Oily sludge handling capability.

3. Ability to handling low concentration sludge from 2000 mg/l up to 50000 mg/l.
4. Rotating ring and automatic spray cleaning system provide self cleaning ability during process and prevent clogging, allowing a continue operation for 24 hour without user assist.

5. Control panel equipped with inverters and PLC for automatic and manual function.

6. Wear free structure, long service life and utilizing a small footprint for installation.
