PolyGeyser


  • 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, like Blue Eco and Performance, for high efficiency.
  • Very little water loss with each waste water dump.

 

Here's how it works
Water enters the filter in the middle of the chamber (A) below the floating beads, and flows up through the beads (B) and out to the pond (C). A pump, injects air into the collection chamber (D) until it is full. The air is then released automatically up (E) through the bed of beads (B), churning loose captured debris (this is the geyser part). The water pump continues to run. The beads fall to below the water intake (A), 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 DF-3 filter can handle up to ± 2,5 kilo feed loading per day and the DF-6 up to ± 5 kilo per day!

In the bottom chamber of the filter (F), 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 15m³/h (DF-3) or 25m³/h (DF-6) 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 andthe filter and rubber couplings.

Pre-filters
The in- and output system of a beadfilter has laterals (slotted pipe) to keep the beads inside the filter and therefore we need a pre-filter to prevent the possibility of large solids (string algae, pine needles, leaves and fish waste) coming in from a bottom drain or submersible pump. We strongly recommend the use of a pre-filter in the above-described situations.

There are several options that can be used as a pre-filter, like a vortex with filter brushes, the Turbo Vortex and the Ultrasieve III.
