HUBER Band Screen CenterMax® Maximum separation efficiency through reliable wastewater screening, retention of fibres and hair.
Maximum separation efficiency through reliable screening
- Maximum retention of fibres and hair
- Operating reliability for membrane bioreactors
- Especially for narrow channels and high throughputs
- High separation efficiency
The HUBER Band Screen CenterMax® is available in different designs and suitable for numerous applications of solids-liquid separation.
The screen can be equipped with a mesh, perforated plate or a folded perforated plate ("Star" design), according to the specific application requirements.
Design and Function
Whilst the wastewater flows into the open front side of the screen and out through the screening elements on the left and right side (viewed in flow direction), solids are retained on the inner surface of the screening elements leading to gradual blinding of the surface, which has an impact on the level difference in the channel. Cleaning of the filter elements starts at a defined water level in the channel upstream of the screen. The filter elements start to circulate, thus transporting the screenings upwards and out of the channel.
In the upper part of the screen a spray nozzle bar sprays water onto the surface of the filter element from outside to remove the solids from the surface and flush them into an internal trough installed in the upper part of the screen from where the screenings are discharged by gravity. The screenings are usually treated further in a HUBER Wash Press WAP® (see separate brochure).
