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, maintaining sludge dewatering stability in the 70-85% range. Its compact design reduces capital investment and floor space requirements while minimizing odor and phosphorus release from sludge in concentration tanks.

1. Conditioned sludge flows into the filter chamber from the flocculation tank and is pushed toward the discharging end
2. Water separates from sludge as the gap between shaft threads increases, flowing out through moving and fixed ring gaps
3. Moving and fixed rings self-clean to prevent machine blockage
4. Filtered sludge cakes are pushed forward by the shaft and discharged

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

• Compact footprint: Suitable for space-constrained installations and replacement of existing units
• No blockage: Self-cleaning mechanism handles oily sludge without clogging, requiring minimal flushing water
• Cost efficient: Low power consumption (0.1-0.01kwh/kg-DS) reduces wastewater treatment system operating costs
• Automated operation: Easy to operate with fully automatic control via electric cabinet
