Description

The hour glass shape of Superbead Filters make them easy to recognise. This shape is necessary to get a laminar through-flow which is as high as possible and in a way that keeps the floating bed steady. This way the debris is trapped and so helps the biological process. A beadfilter can process very high feeding rates, both mechanically and biologically. This is the result of their high efficiency and the usable surface of the beads (1300 sq metres per cubic metre). Trapped dirt is removed quickly by the very effective back-washing system without destroying the bead biofilm. Using this technique just makes the biofilm more active again. Dead areas to trap mulm in the filter are eliminated because of the unique shape with no corners.
