Polygeyser Bead Filters

 polygeyser sm

The PolyGeyser beadfilter is a real revolution in filter technique!

The PolyGeyser beadfilter is automatically self-cleaning without moving parts or electronics, contains EN (Enhanced Nitrification) media 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 amp water pump (like Oase, Messner, Red Dragon, and Sequence) can be used as a circulation pump. The PolyGeyser has the lowest possible pressure

loss because it uses no multiport-valve. Inlets and outlets are 3".   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 filtrationin one unit

  • Mechanical filtration down 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


Clarification :

Bead filters perform well in the control of suspended solids across a broad spectrum of conditions. Bead filters capture solids through four identifiable mechanisms (Table 1). With the exception of adsorption, the solids capture mechanisms are physical in nature and are common to all types of granular media filters. As a general observation, the filters seem to control fine colloidal particles best with some biofilm development. This suggests that the biofilm absorption process is an important mechanism in the control of fine suspended solids and thus water clarity. Studies have shown that bead filters capture 100% of particles > 50 microns and 48% or particles in the 5-10 micron range per pass (Figure 1).



Figure 1. All particles above 50 microns are removed in the first pass through the filter and the remainders are removed with multiple passes


Biofiltration :

In the biofiltration mode, bead filters are classified as fixed film reactors. Each bead (Figure 2) becomes coated with a thin film of bacteria that extracts nourishment from the wastewater as it passes through the bed. There are two general classifications of bacteria, heterotrophic and nitrifying, that are of particular interest (Table 2). The two bacteria co-exist in the filter, and understanding their impact on each other as well as on the filter is critical.


Figure 2. The bacterial film that coats each bead contains the nitrifying bacterial population. Heterotrophic bacteria also form a thin biofilm layer on each bead. The nitrifying bacteria compete with the heterotrophic bacteria for space.

Filter Acclimation :


Figure 3. Two specialized types of nitrifying bacteria convert toxic ammonia and nitrite to the relatively safe nitrate. Bicarbonate ions and oxygen are required in large amounts.


Figure 4. Tan and nitrite concentration build-ups are normally observed during the initial acclimation of a biofilter.
