Powerful yet compact and a breeze to operate
The PWTech Dewatering Press improves upon standard screw press performance with its very low-maintenance, blinding-resistant Volute drum. Extremely low energy-draw, excellent dewatering performance, as well as low operator attention requirements make this the most cost-efficient press on the market. Flexible system configurations and numerous adjustable operating parameters ensure optimal solids separation, even as your feed sludge changes.
KEY ADVANTAGES
- Compact, energy-efficient design reduces operating costs by up to 95% compared to traditional dewatering methods
- One-step thickening and dewatering, even with sludges as thin as 0.03% TS
- Self-clearing gaps in the drum minimize the need for spray washing during operation
- Does not require daily wash-down unless press will be idle for more than three days
- Fully automated system minimizes oversight
- Quiet, odor-free operation ideal for municipal and industrial settings
When to Use the Volute™ Dewatering Press
The PWTech Volute Dewatering Press is ideal for applications where low lifecycle cost is a key consideration, or where the type of sludge would overwhelm traditional screw presses, belt presses, or centrifuges.
- Waste biological sludges (including WAS, fixed film, MBR, aerobic and anaerobic digested)
- Blended sludges
- Potable water sludges (including alum, ferric, and PAC sludges)
- DAF skimmings from slaughterhouses and other agricultural processes
- Oil sludge from machining operations
- Wastes from textile processing
- Food processing and wash-down wastes
- Industrial sludges
