The On-Site Sludge Dewatering Machine is a continuous solid-liquid separation system engineered for industrial and municipal wastewater treatment. By integrating gravity thickening and multi-disk screw extrusion, the unit reduces sludge volume by up to 80%–90%, directly lowering hauling and disposal costs. Designed for seamless integration into existing plant layouts, it operates reliably with minimal operator supervision.
Key Performance Snapshot:
- Volume Reduction: 80%–90% reduction in sludge volume
- Solid Recovery Rate: ≥ 95% solid capture efficiency
- Operation Mode: Fully automated 24/7 continuous operation
Key Features
Anti-Clogging Design: Movable and fixed rings replace traditional filter cloth, preventing blinding and reducing wash water consumption by up to 85%.
Low-Speed Operation: Operates at 2–4 RPM, resulting in low mechanical vibration, minimal noise emission, and extended service life of internal components.
Compact Footprint: Combines thickening and dewatering zones into a single skid-mounted frame, requiring minimal vertical and horizontal installation space.
Continuous Auto-Operation: PLC-controlled integration enables unattended 24/7 operation with automatic polymer dosing and sludge feeding regulation.
Corrosion-Resistant Contact Parts: All wetted structural components utilize AISI 304 / 316L stainless steel, ensuring durability in aggressive chemical environments.
