Why Aquaforte Ultrabead® ?
Easy..
The Ultrabead bead filter is without competition the BEST possible filtration solution for all types of outdoor pools. Although most pool equipment vendors promote the use of sand filters for outdoor pools, similar to indoor pools, the real maintenance needs of these sand filters are often overlooked – for example, sand filters clog up very quickly during the period of pollen (early May to Midsummer). On the slightly windier days that follow the sunny and windless spring days, we are talking about hours here. For smaller, covered pools, pollen is usually not a major problem, as the pool is covered again after swimming, but in the case of particularly shaped or larger pools, covering is often not possible at all.

How does Ultrabead® work?
Bead filters are sealed pressure vessels filled with millions of floating plastic beads. As these beads are slightly lighter than water and do not rest at the bottom of the filter vessel, they ensure a freer flow of water and thus significantly more efficient mechanical filtration.
- Ultrabead mechanical filtration: the pressure of the pump pushes the water through the beads, while the dirt particles get trapped between the beads. The pressure of the beads presses the water through the beads, while the bead pressure forces the beads through the water. The biggest advantage of the Ultrabead filter here is the filter cleaning technology. The filter is cleaned in cooperation with an air pump. The air pump allows the entire contents of the filter to be shaken out and, after the filter washing cycle, the entire inside of the filter is completely cleaned. In comparison, sand filters have a static filter material and the washing process usually only flushes out the larger particles of dirt that have accumulated on the sand surface. Particles stuck in the deeper layers of the filter sand will remain there until the filter sand is replaced. Ultrabead filter media never needs to be removed, further cleaned or replaced.
- Ultrabead biological filtration (in the case of biological water bodies): the surface area of plastic beads is about 1600 m²/m³ per bead. The biofilm layer on top of the beads thus provides a huge additional surface area for bacteria to colonise and remove nitrogen, nitrite and nitrate.
How and how often do I need to maintain my bead filter?
Backwashing, or cleaning, is done in the same way as for sand filters – you turn the valve to the appropriate position and after a few minutes turn it back to normal position. In the meantime, a few movements of the multiport valve and turning the air pump on/off. At the same time, the transparent wash water monitoring window allows you to monitor the progress of the filter washing and to stop the filter cleaning at exactly the right moment (if the wash water is visibly clean). Saves a huge amount of water as there is no need to use too much water for backwashing. Exactly as much as you need. If the system is optimally designed, the cleaning cycle will generally need to be done once a month. The maintenance interval will, of course, also depend on how much the pool is used. For example, during the pollen season in spring, the filter may need to be cleaned a little more frequently if the pool is located close to pine trees or other trees with a high pollen content, etc. The frequency of cleaning will vary depending on the season.
- Clean water (filtration up to 10 microns ! )
- Compact (< 1m²)
- Lower energy consumption (thanks to multiport valve bypass)
- Highest quality filter media
- Possibility to add automatic backwash system
- A reliable solution for outdoor pools that works already in many places in Estonia!
Technical data:
- Filters are supplied with the specified filter material (plastic beads).
- All models come standard with an air pump valve design and a standard multiport valve bypass to reduce the obstruction caused by the multiport valve during the daily filtration process.
- UltraBead filters are made from unbreakable thermoplastic using a reliable injection moulding process.
- The UB60 and UB100 have 63mm pipework for optimum water flow.
- The UB140 model has Ø75 mm pipework, which provides even lower resistance to water flow.
- Recommended pump capacity: the pump should be able to pump about half the water volume of the pool through the filter in 1 hour at a head of 2-3 metres (0.2-0.3 bar).
- Maximum filter capacity: UB-60 – 18 m³/h, UB-100 – 24 m³/h, UB-140 – 30 m³/h (25 m³/h with Ultratronic backwash)
- Maximum working pressure 2,5 bar.
Recommended water volumes per Ultrabead filter:
- UB-60 up to 80m³
- UB-100 up to 120m³
- UB-140 up to 200m³
In fish-inhabited water bodies, consider 2x smaller water body volumes.
