Self-cleaning, clog-free design with energy consumption at just 1/20 of a centrifuge. Ideal for municipal and industrial wastewater sludge dewatering applications.
Advanced Solid-Liquid Separation Technology
The Volute Sludge Dewatering Machine represents cutting-edge solid-liquid separation technology. Its innovative filtration system features fixed and moving rings stacked together with a spiral shaft running through the assembly. Sludge undergoes gravity thickening before advancing to the dewatering zone, where gradually decreasing filter gaps and spiral pitch combine with back pressure plate resistance to generate substantial internal pressure. This process progressively reduces sludge volume, achieving thorough dewatering and producing solid mud cakes.
Industry Applications
This versatile equipment serves multiple industries including municipal sewage treatment, domestic wastewater processing, food and beverage manufacturing, chemical production, papermaking, printing and dyeing operations, pharmaceutical processing, electroplating facilities, oil field operations, mining applications, and animal husbandry operations.

Key Advantages
Cloth-Free Self-Cleaning Design for Oily Sludge: Innovative fixed and moving ring system eliminates traditional filter cloths. The rotating spiral shaft continuously drives moving rings to sweep filter gaps in real-time, providing automatic self-cleaning that prevents clogging and handles oily sludge effectively.
Ultra-Low Speed Operation with Exceptional Energy Efficiency: Low-speed operation ensures minimal noise and outstanding energy savings. Consumes only 1/8 the energy of traditional belt presses and 1/20 the energy of centrifuges, significantly reducing long-term electricity costs.
Direct Low-Concentration Sludge Dewatering Saves Infrastructure: Capable of directly dewatering low-concentration sludge, eliminating the need for large sludge thickening tanks and reducing initial infrastructure investment for water treatment plants.
Fully Automated Operation for Simplified Management: Supports complete automatic control without manual intervention during dewatering processes, making daily operation and management straightforward and worry-free.
Frequently Asked Questions
Our plant's sludge has a high oil content. Will this machine clog easily?
No clogging issues. The equipment uses stacked metal fixed and moving rings instead of traditional filter cloths. During operation, the rotating spiral shaft continuously drives moving rings to automatically clean gaps, providing self-cleaning functionality that prevents clogging and effectively handles oily sludge.
Does this dewatering machine consume a lot of electricity and make significant noise?
Both energy consumption and noise levels are extremely low. The equipment operates at low speeds for quiet performance. Power consumption is only 1/8 that of belt presses and 1/20 that of centrifuges, making it environmentally friendly and cost-effective.
Does the sludge need to be highly thickened before entering this machine?
No pre-thickening required. A core advantage is direct dewatering capability for low-concentration sludge, allowing you to bypass expensive dedicated thickening tanks and directly reduce wastewater treatment facility infrastructure costs.
