Types Of Filters

  1. BUBBLE BEAD FILTER (BBF)
    The bubble bead filter (BBF) is an entry-level bead filter for lower stocking densities and feed loads. An easily back-washed filter requiring no additional air pump, you can backwash this filter in a tuxedo. This filter is best utilised on ponds, aquarium systems and lightly loaded aquaculture systems.

  2. PROPELLER WASHED BEAD FILTER (PBF)
    The propeller washed bead filter (PBF) is the workhorse bead filter for heavier feed rates and stocking densities. These filters can handle higher pressures, higher ammonia levels and higher feed rates due to their more aggressive backwash. Utilising a propeller driven by a motor mounted on top of the filter, the more aggressive backwash allows better control of the biofilm thickness and more waste to be removed at backwash time. 

  3. POLYGEYSER BEAD FILTER
    The polygeyser comes in several variants, but they all rely on the same pneumatically triggered automated backwash mechanism. With automated air backwash, the flow does not need to be stopped. Backwashing can be set to certain intervals depending on loading and more frequent backwashes means higher ammonia removal, greater solids removal and better water quality.
