Volute Thickener

Volute sludge thickener is a reliable continuous solid-liquid separation equipment dedicated to sludge concentration. It operates at low speed with high stability, efficiently concentrating sludge from secondary sedimentation tanks continuously. Suitable for municipal and industrial wastewater treatment, it replaces traditional thickening tanks to save investment and space while avoiding odor and phosphorus release.

Based on the mechanical screw pressing principle, it applies gentle progressive pressure for efficient concentration with low energy consumption. This volute sludge thickener performs well in various pretreatment scenarios for deep dewatering systems and conventional dewatering equipment. Automatic operation and self-cleaning design ensure easy maintenance and stable long-term performance.

Core Advantages

- Compact structure and high concentration efficiency, effectively saving land and infrastructure investment.
- Low-speed and low-energy operation, without continuous high-pressure washing, with remarkably low operating cost.
- Non-clogging and self-cleaning performance ensures stable operation and less maintenance.
- Fully automatic continuous operation with strong stability and high reliability.
- Closed operation reduces odor and avoids phosphorus release, environmentally friendly.

Design Features

Non-Clogging Volute Structure: It achieves effective self-cleaning through relative ring movement, preventing clogging reliably. It needs only small amounts of low-pressure water for cleaning, with no high-pressure flushing required.
Dual-Gradient Screw Design: It adopts a dual-gradient screw structure with gradually reduced pitch and enlarged shaft diameter. This design forms progressive pressure from inlet to outlet, ensuring sufficient and stable concentration for various sludge types.
Low-Speed Automatic Operation: The equipment runs at low speed with low noise and low abrasion. It is equipped with an automatic control system to realize continuous unmanned operation, with few wearing parts and long service life.
Wear-Resistant Key Components: Screw blades and rings are surface-hardened for excellent wear resistance. Key parts are precisely processed to ensure high accuracy and reliable long-term performance.
