Yes it is possible, but ozone treatment is sufficient to treat chloramines in particular, UV would bring an additional cost in investment and operation without bringing any advantage in the treatment of swimming pool water. We can provide you with both systems, and advise you in your choice. Air et Eau Systèmes provides this equipment and offers preventive maintenance and assistance contracts, everywhere in France.
Both technologies allow disinfection. Offering the 2 systems , we specify:
When they are part of your installation, both are effective and act during the filtration cycle.
Ozone : Requires 1 ozone generator unit. Ozone acts by oxidation of micro-organisms. Because its use can be tricky, we recommend it for more professional use. Be aware that there are also professionally designed boxes for individuals.
UV-C Lamp : Only UV "C" is effective for disinfection. The UV lamp works by "burning" the micro-organisms inside the lamp. A lamp is very simple to integrate into an installation. No side effects. As easy for professional installation as for a private individual. We recommend the UV-C LED lamp for its greater longevity , its low energy consumption and its ecological dimension.

The oxidation of swimming pool water operates dechloramination and disinfection:
As a preliminary and in an associated manner, the first water treatment for swimming pool basins is filtration , which must:
- retain as many impurities as possible: This promotes a reduction in the consumption of coagulation, cleaning and oxidation reagents, and partly prevents the formation of chloramines. This limits the supply of new water, the energy consumed for its heating and its circulation, the need to dechloraminate,
- without undergoing too rapid rises in pressure drop, frequent stops and the use of large volumes of backwashing water.
Swimming pool water filtration uses different types of filters:
o thick bed filters (sand, glass granules, etc.),
o precoat filters (diatomite, perlite, micronized cellulose fibres),
o cartridge filters, pocket filters,
o microfiltration membranes.
The good performance of filtration affectsdechloramination and disinfection:
The average filtration efficiency, the filtration threshold, the retention capacity, the suitability for backwashing of filter media/filters are determined based on standardized test methods (developed by groups of experts in the form of international standards) and make it possible to compare/verify/better exploit filtering media/filters:
- NF EN 16713-1: filters for private swimming pools
- NF EN 13443-2+A1: industrial filters (1-80 µm) for water (applicable to filters for public swimming pools)
- developed method IFTS-FEEIS-01: submicronic filters (0.2-1 µm) (applicable to membranes)
The IFTS has many test benches and reference products, and routinely ensures the qualification of performance according to these methods on behalf of manufacturers, design offices, local authorities and other principals.
Draft texts for filtration standards are currently in progress, to identify the mode of conducting tests on in-situ filters to check the consistency and performance of filtration systems during installation, commissioning service or operation in a public swimming pool. (Afnor S52L committee)
To be trained in these characteristics , in the standards published for less than 10 years or in the process of being drafted and tested, have the filtration performance of filter media/filters determined :
