Energy Saving Volute Press Sludge Dewatering for Sludge Cake Production

The BOEEP Energy-Efficient Volute Sludge Press is a revolutionary solid-liquid separation device engineered for efficient, continuous production of high-dry-content sludge cakes. Its unique volute structure combined with a variable-pitch screw shaft enables progressive squeezing and dewatering of municipal and industrial sludge without requiring high-pressure rinse water, achieving a 70% reduction in energy consumption compared to traditional equipment. With a maximum single-unit processing capacity of 90 m³/h and consistent sludge solids content of 20%-25%, it represents the ultimate solution for reducing total cost of ownership (TCO) in sludge disposal.

Core Advantages: Delivering Four Core Values to Customers

Exceptional Energy Efficiency with Minimal Operating Costs

Achieve up to 70% reduction in energy consumption, supported by a low-power main motor (2.2–7.5 kW) that eliminates the need for high-pressure pumps and their ancillary power units. Furthermore, the system operates without flushing water, completely removing related water consumption and costs.

Flocculant Savings
Optimized flow paths enhance contact between sludge and polymer, improving flocculation efficiency and enabling a 15–30% reduction in PAM usage.

Higher Sludge Recovery & Drier Cake Output

Multi-stage pressurization combined with an adjustable back-pressure plate establishes a controlled pressure profile, resulting in solid cake with 20–25% dry solids content. This significantly reduces sludge volume, lowering both transport and disposal expenses.

Fully Automated Operation & Low Maintenance

An integrated PLC control system enables one-touch start/stop, adaptive pressure adjustment, overload protection, and remote monitoring—ensuring reliable, unattended operation.

Screen-Free Design
The unique volute structure eliminates the need for filter screens, preventing clogging issues common in belt or screw presses. This design removes the need for routine rinsing and cuts maintenance efforts by over 80%.

Robust Construction & Broad Adaptability

The core screw shaft is manufactured from 316L stainless steel and coated with tungsten carbide for superior wear resistance. Its lifespan exceeds that of conventional components by more than three times, even under harsh, abrasive conditions such as highly corrosive industrial sludge.
