Rotary Drum Screen Work Process
The drum is horizontally rotated under the support of four runners. It is driven by TEFC reducer, anti-corrosion roller chain and stainless steel sprocket. The spray system automatically sprays clean water. The raw water flows in the inner of the drum through the overflow tank. The filtered raw water is diverted to the central drainage area through the bottom plate deflector and flows into the next sewage treatment unit; the slag in the raw water is blocked on the inner surface of the drum filter and is discharged as the drum rotates.

Rotary Drum Screen Advantages
1. Automatic discharge
2. The uniformity of water-distribution increases the treating capacity.
3. It is equipped with reverse flushing device to prevent the screen clogging and easy to clean.
4. Double overflow plate to prevent wastewater splash.
5. SUS304 or SUS316L material convenient in maintenance, which has high mechanical strength, no deformation and long life.
6. It can be customized with different mesh size and mesh type.
