Abstract

La présente invention concerne un système de désinfection qui présente les caractéristiques suivantes: une haute efficacité, la production in situ de chlore et d'ozone qui élimine les bactéries et les autres organismes pathogènes de l'eau des piscines, ce qui évite ainsi le développement d'algues et de champignons. Avec la mise en oeuvre de ce système, on évite la production, le transport, le stockage et la manipulation de produits chimiques pour effectuer un traitement considéré comme ÉCOLOGIQUE. Son automatisme et sa surveillance à distance facilitent le fonctionnement et réduisent les risques de défaillances humaines relativement au dosage manuel. C'est un système sûr qui évite le risque lié à la manipulation de produits chimiques pouvant constituer un danger en l'absence d'une vigilance adéquate. Avec la mise en oeuvre de ce système, on se conforme à la normativité nationale PROY-NOM-000-SSA1-2005 et à la normativité internationale. Les éléments constitutifs et la fabrication du système seront en majeure partie nationaux.
