Dechloramination by UV rays
Water quality: watch out for chlorination by-products!- eyes, skin and breath membranes get irritated,
- water over-consumption,
- energy over-consumption for heating and dehumidification,
- polluting discharges.

What kind of prevention for public swimming pools?
Today most collective swimming pools and spas are treated solely using chlorinated swimming pool products. Although the conventional microbiological risk (bacteria, viruses) is controlled effectively by chlorine treatment, the risk linked to these parasites is not taken into account. Chlorine is certainly an effective disinfectant but it has no effect on these parasites (Cryptosporidium, Giardia, etc.). Public facilities only using chlorine are therefore not protected against these risks and may encounter water quality problems.
Risks present in collective swimming pools:
- Chemical risk: combined chlorine level often close to limits set by regulations (0.6 ppm in France),
- Biological risk: possible presence of bacteria, coliforms, E. coli, streptococcus and also Cryptosporidium, Giardia and Toxoplasmas.
Consequences of poor management of these risks for:
- Health: respiratory irritation for lifeguards, swimmers, babies; epidemics due to parasites
- Finance: substantial water renewal (costs of heating, treatment); closure of the facility
- Environment: discharge of polluted water
- Image of the facility: poor image, closure
Of all the solutions on offer to local authorities (UV, Ozone), only one makes it possible to:
- Effectively reduce the levels of combined chlorine through effective destruction of chloramines
- Prevent the risks of presence of Cryptosporidium, Giardia and toxoplasma
- Maintain a quality of water beyond reproach in the swimming pool or spa
- Improve management of water renewal and discharges
Ultraviolet treatment!
The water treatment process using ultraviolet reactors is the only system that guarantees ideal UV-C disinfection and optimal destruction of chloramines. The pool is suitable for bathing and safe for the supervisory personnel.
Water disinfection guarantees protection of everyone's health, substantial savings in water maintenance and consumption, a better image for the facility and contribution to sustainable development.
