Recently installed in California, the HUBER Screw Thickener S-DRUM delivers efficient, reliable sludge thickening through a smart and robust design.
The S-DRUM combines a flocculation reactor with an integrated stirrer and a cylindrical stainless steel wedge-section basket that effectively retains solids. A slow-rotating, variable-speed screw gently conveys sludge upward, allowing water to drain while achieving consistent thickening. Performance is easily adjusted via screw speed and a height-adjustable weir plate, while an external rotating spray bar keeps the basket clean for continuous operation.
Key benefits include:
- Up to 80% sludge volume reduction
- Robust, wear-resistant design for high solids and coarse material
- High reliability with clog-free operation and slow screw speed
- Low operating costs with minimal power and spray water consumption
- Quiet, odor-free operation with no vibration and no lubrication required
