Screw Disc Presses for Thickening and Dewatering of Wastewater Sludge (Excess, Raw, or Digested)
For effective further management, sewage sludge must be thickened or dewatered to reduce its volume—either for subsequent processing or final disposal.
We offer sludge thickening up to 8–10% dry solids and dewatering to 18–23% dry solids.
This is achieved using our modern screw disc presses, which provide the required performance with low energy consumption and reduced investment and operational costs.
The simple and compact design of the press allows for easy maintenance and servicing, and ensures user-friendly operation.
Sludge is fed to the thickening or dewatering press via a feed pump, initially entering the flocculation chamber. This chamber optimises flow using an overflow system. The flocculation process is enhanced by slow mixing with a polymer. The resulting mixture is directed to the screw-disc unit, which features fixed and moving discs acting as a self-cleaning filter.
We offer:
• Screw disc presses with capacities ranging from 1 to 38 m³/h,
• Polymer preparation and dosing stations,
• Progressive cavity feed pumps for sludge,
• Progressive cavity dosing pumps for polymer solution.
As part of the equipment selection process, we provide an assessment of the current and projected conditions at the site, along with the development of a technological design for the sludge dewatering system.
