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

Design sketch: HUBER Band Screen CenterMax®
Design sketch: HUBER Band Screen CenterMax®

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).

  • Perforated plate: 1 ‒ 10 mm
  • Star-type perforated plate: 1 ‒ 2 mm
  • Mesh: 0.5 ‒ 1 mm
  • Completely made of stainless steel, pickled in an acid bath
