Product Description

Screw Press Sludge Dewatering System
Overlapping Screw Press: Sludge Dewatering System

This robust dewatering technology is extensively implemented in municipal WWTPs and industrial sectors including petrochemicals, papermaking, chemical fibers, pharmaceuticals, and leather processing. Field verifications confirm significant economic returns and environmental benefits.

Process Workflow
  • Sludge Feeding: Slurry is conveyed via progressive cavity pumps; in-hopper agitators maintain homogeneous solids concentration.
  • Polymer Conditioning: Automatic dosing systems prepare optimal flocculant solutions (e.g., cationic PAM).
  • Flocculation & Separation: Turbulent mixing induces alum-floc formation; conditioned sludge enters overlapping screw assembly.
  • Dewatering & Discharge: Filtrate discharges through moving ring gaps; dewatered cake (18-25% DS) exits at terminal chute.
  • Closed-loop Operation: Continuous feed/discharge enables 24/7 unmanned automation.

Technical Specifications

Model Processing Capacity Dry Solids Output Technical Advantages
LK-wnts5 ~10 m³/h 100–150 kg-DS/h Self-cleaning & clog-free design
LK-wnts6 ~25 m³/h 250–450 kg-DS/h 24/7 continuous unmanned operation

Key Technical Advantages

1. Universal Applicability: Processes both high/low solids sludge (2,000 mg/L to 50,000 mg/L). Eliminates thickening tanks, reducing capital costs by 25-40%.

2. Compact Footprint: Space optimization is 30-50% smaller than conventional belt presses.

3. Anti-Clogging Performance: Self-cleaning mechanism ensures zero manual screen cleaning and reduces rinse water consumption by 60-70%.

4. Low-Speed Operation: Spiral shaft rotation at 2-3 RPM ensures power consumption <1.5 kW·h per ton DS and noise levels ≤65 dB(A).

5. Automated Control: PLC integration synchronizes pumps and dosing systems for 24/7 operation.

6. Robust Construction: 304/316L stainless steel body with a service life exceeding 15 years.
