Bead Filters

Most compact pond filter on the market

One of the great advantages of a bead filter is that it provides both biological and fine mechanical filtration. In practice, this means that the water is crystal clear because the bead filter can filter up to 10 microns (!) (finer than a sand filter!) but also that the water is healty (for people and fish). The bacteria that grow in the bead filter take care of the nitrogen cycle (ammonia -> nitrite -> nitrate). For swimming ponds this means that filtration without plants is possible, if desired, because the bead filter provides the complete biological filtration. Of course, you can still have plants in the pond, but these have a more decorative function. In practice, this can result in large savings during construction of the pond (less space and liner, fewer plants and labour).

How it works

Bead filters are closed pressure vessels filled with millions of plastic beads. Because these beads float, they provide the mechanical filtration, and because of their large bonding surface they also provide biological filtration.
Mechanical filtration: the beads float in a closed vessel and are therefore very close to each other. The water is pushed through them by the pressure of the pump, while the dirt particles become trapped among the beads. As the filter is used for a longer period of time, the biofilm around the beads becomes thicker and thicker, allowing increasingly fine dirt to be collected (down to 10 microns!).
Biological filtration: the plastic beads have an adhesion surface area of about 1600 m²/m³. The biofilm layer on the beads therefore provides a huge amount of surface area for the bacteria to break down ammonium, nitrite and nitrate.

AquaForte BeadFilters

New generation AquaForte UltraBead® Beadfilters

Most compact all-in-one professional filter system on the market


An UltraBead requires at most 1 m² in the technical room. The internal piping system in combination with the by-pass ensure little resistance. This ensures optimum efficiency of the pump and filter. Maintenance of a bead filter is very easy; backwashing takes just a few minutes. Thanks to the blower, a lot of water is saved compared to sand filters and the backwash water is 100% useable for the garden.
