PolyGeyser Beadfilter

The self-automated backwash process requires no moving parts or electronics.

Under development for several years, the patented PolyGeyser® technology is capable of handling ammonia loads 50% – 100% higher than standard bead filters at a fraction of the water loss and head loss.

The innovative backwash process prevents caking and clogging, keeping your day-to-day operations moving along smoothly. The backwash is gentle, keeping the biofilm intact while allowing the system to operate for long periods of time with no maintenance.

The self-automated backwash process requires no moving parts or electronics.

Under development for several years, the patented PolyGeyser® technology is capable of handling ammonia loads 50% – 100% higher than standard bead filters at a fraction of the water loss and head loss.

PolyGeyser Benefits:

  • Automatic backwashing – these filters clean themselves
  • PolyGeyser has been tested and proven for over 20 years
  • Optional Airlift offers additional energy savings
  • Superior biological filtration with 1.5x Bubble Beads
  • The biofilm remains protected from frequent backwash cycles
  • Simple design has no moving parts to break
  • Water loss is reduced – only concentrated sludge is removed

The PolyGeyser beadfilter is a real revolution in filter technique. Designed by the father of the Bubble Bead filter; Dr. Ron Malone.

The PolyGeyser beadfilter is automatically self-cleaning without moving parts or electronics, contains EN (Enhanced Nitrification) media (see photo) that offers 50% to 100% greater nitrification than standard beads, and is capable of providing mechanical filtration down to 5 micron particle size.

The PolyGeyser filter can be installed underneath or above water level. Any low Watt water pump like Sequence or Oase can be used as a circulation pump.

The PolyGeyser has the lowest possible pressure loss because it uses no multiport-valve.

In and outlets are 3” (±75mm). It’s already being used in aquaculture, and now it’s ready for koi ponds.

  • Fully automated cleaning without moving parts or electronics!
  • No more clogging filters when you forget a cleaning cycle.
  • Special beads that offer 50% to 100% greater nitrification.
  • Bio and mechanical in one unit.
  • Mechanical filtration up to 5 micron.
  • For installation underneath and above water level.
  • Can be used with low wattage pumps for high efficiency.
  • Very little water loss with each waste water dump

How The PolyGeyser Beadfilter Works

Water enters the filter in the middle of the chamber below the floating beads, and flows up through the beads and out to the pond. A pump, injects air into the collection chamber until it is full.

The air is then released automatically up through the bed of beads, churning loose captured debris (this is the geyser part). The water pump continues to run. The beads fall to below the water intake, so the new pond water washes down through the beads to the chamber below.

As the filter refills, the beads float up to the top of the filter, and the cleaning process is completed. The air pump can be adjusted to fill the chamber for automatic cleaning every two to six hours, keeping the filter media bed at an optimum performance level and debris free. In this way the filter can handle up to ± 2 kilo feed loading per day! In the bottom chamber of the filter , the captured debris settles out, and can be released by simply opening a valve at the convenience of the owner (normally every 2 or 3 days), however the chamber is quite large, so the filter can go for weeks without being flushed, and the flushing process uses very little water.

The pump doesn't even need to be turned off to purge the collection chamber.

Every filter is equipped with a window to watch the backwash procedure. Maximum pump speed is 10m3/hour with a maximum head pressure of 0,7 bar (7 metres). The filter comes with a flow meter for the air pump, a check valve to be installed in between the pump and the filter and rubber couplings.
