A Volute Press Adapted for the Tough-to-handle Sludges
For more challenging applications, the Volute Duo™ Screw Press offers enhanced performance. Featuring twin counter-rotating screws within a single drum, this advanced system breaks up and processes difficult sludges—fibrous, inorganic, or oily—that other presses can’t handle. With the same energy efficiency and low-maintenance benefits as the original Volute™, the Duo excels in handling high-demand environments without compromising performance.
KEY ADVANTAGES
- Requires minimal maintenance with no brushes or wipers
- Offers the highest dewatering capacity of any available screw press
- Delivers consistent performance and 24-hour unattended operation
- Uses up to 95% less power than other dewatering processes
- Consumes minimal wash water, enhancing operational efficiency
- Processes feed sludges ranging from <0.2%TS to >8%TS
When To Use the Volute Duo Screw Press
The Volute Duo™ Screw Press is versatile across sludge dewatering applications, excelling in conditions that cause clogging or blinding in traditional screw press designs. Key applications include:
- Dewatering WTP sludge (alum, ferric and lime sludges)
- Managing sludge in pulp and paper processes
- Processing raw manure in agricultural settings
- Supporting dredging and land remediation projects
- Handling raw primary sludge efficiently
- Dewatering any fibrous or gritty/inorganic sludges
