Abstract
Appareil de traitement de l'eau comprenant un récipient de contact (60) s'étendant verticalement, dans lequel l'eau est mise en contact avec l'ozone (53), et un récipient de retour (61) qui contient une colonne (24) d'eau présentant une hauteur suffisante pour que l'eau circule à travers des étages de filtrage en aval (12). L'ozone est extrait de l'eau et le débit d'injection d'ozone est contrôlé et automatiquement régulé de sorte qu'il n'en reste pas de grandes quantités dans l'eau pénétrant dans les étages de filtration (12). L'ozone est produit dans des éléments allongés (58) qui sont refroidis par l'eau du processus et qui sont positionnés de manière à servir de mélangeur statique pour cette eau.
