Dechloramination by UV rays

Water quality: watch out for chlorination by-products!
Classical water treatment systems can irritate eyes and mucous membranes of swimmers and pools staffs:
  • eyes, skin and breath membranes get irritated,
  • water over-consumption,
  • energy over-consumption for heating and dehumidification,
  • polluting discharges.
The BIO-UV UV-C treatment prevents risks linked to pathogenic micro-organisms present in water that can be a source of disease for humans. Their presence makes it necessary to treat the water for users' health. This is why it is important to take stock of the risks associated with inadequate water treatment. The pbio-uv-mp-light-range-for-dechloraminationarasites (Giardia lamblia, Cryptosporidium parvum or Toxoplasma gondii) are microscopic protozoans originating from vertebrates. They have been shown to be responsible for major human water-based epidemics around the world, due to the increasing use of surface water and recycled water. generate. 


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.
