All pools have a filtration system to keep the water clean, free of algae and bacteria. The two most important components of the treatment plant are the filter and the pump.
In a swimming pool, the filtration system is an essential element that removes impurities from the water. In the center of the system, the pump circulates the water that is then introduced into the skimmers, passes through the filter and then through the water treatment systems, before returning it through the impulsion nozzles, purified.
The filtration system provides you with a water flow that is renewed several times a day, preventing the water from stagnating and becoming contaminated with bacteria and algae.
The golden rule for choosing the most suitable filtration system is to make sure that it is adapted to the volume of water in your pool.
The key element in filtration is the passage of water through the filter.
This process works in a completely closed circuit. The quality and type of filter are therefore two decisive aspects so that, when the water is in circulation, it always comes out completely clear.
To select the most suitable filter for your pool, an influencing factor is the volume of water to be filtered (volume of the pool, in cubic meters or m3).
The second criterion to choose properly is based on the needs of filtering and saving water. There are 3 main types of filters:
Sand filters: sand with a fineness of about 40 to 50 microns is used as the filter medium. Requires regular backwashes to maintain maximum efficiency level.
Cartridge filters: one (or more) filter cartridges are used as a filter medium with a high filtration fineness between 15 and 20 microns. In addition, cartridge filters do not require backwashing for maintenance. All you have to do is rinse the cartridge regularly, with the advantage of saving water (no backwash).
Diatomaceous filters:
Filtration method that offers the highest filtration fineness (10-15 microns), but requires more maintenance.
Also, you should know that the sand in the sand filters can be substituted for glass. This filter medium is a bit more expensive, but offers a higher degree of filtration fineness (20 microns) and faster washing (saving water). Zodiac® Crystal Clear filtration glass is the ideal high-performance material for a good treatment.
