The screw press offers high efficiency, low energy consumption, fully automatic control and stable operation. It directly and continuously reduces water from secondary settling tanks, producing dewatered sludge with stable moisture content of 70-85%. Its compact design reduces capital investment, saves floor space, minimizes odor and phosphorus release, and enhances the capacity of subsequent deep dewatering equipment.

1. Conditioned sludge flows into the filter chamber from the flocculation tank
2. Water separates from sludge as it moves through progressively narrowing gaps
3. Moving and fixed rings self-clean to prevent blockages
4. Filtered sludge cakes are discharged from the end

• Simple process with high efficiency and power savings
• Programmable settings for convenient, accurate operation
• Precise chemical preparation and dosage reduces operational costs

• Compact Design: Fits in spaces unsuitable for other technologies
• No Blockages: Self-cleaning mechanism handles oily sludge without clogging
• Cost Efficient: Consumes only 0.1-0.01kwh/kg-DS (1/8 of belt filter presses)
• Automated Operation: Easy control via electric cabinet with no filter clothes needed
