- Low noise level – ensures a comfortable working environment and reduces noise pollution.
- Flexible adaptation – a choice of different sizes and additional functions to suit individual needs.
- Odor control – closed design prevents unpleasant odors from escaping into the environment.
The SW Drum Sludge Thickener can be purchased as a separate unit or integrated into the SW Belt Sludge Filter Press FTP.
It’s a solution you can count on. Optimize your wastewater treatment processes with a reliable and cost-effective device that ensures smooth operation and minimal maintenance!
How it works
The main purpose of a sludge thickener is to reduce the volume of sludge before further sludge treatment stages. These SW drum thickeners operate on the principle of gravity, filtering the thickened sludge through a special fabric. The filter fabric is tightly stretched around a steel cylindrical frame.
During operation, the sludge mass is fed into the center of the thickener, where it is spread by the deflector blades and pushed to the other end of the thickener. There, it is retained on the filter fabric, while the filtered water is discharged to the next stage of wastewater treatment.
Rotating in a circle, the sludge scraper pushes the sludge into a receiving pit in the center of the thickener, from where the sludge is fed to the next stage of treatment. The sludge thickener is of a closed design to prevent the spread of odors. The gases produced are collected and cleaned to ensure environmental protection.
To improve thickening efficiency, polymers can be added to the thickening process to form sludge flocs, which are then easier to separate.
In some cases, drum thickeners can be equipped with an automatic control system that regulates the speed and efficiency of the thickening process according to the sludge flow conditions and density level.
