Abstract

La présente invention concerne un appareil d'amélioration de la qualité de l'eau pour la gestion de la qualité de l'eau au quotidien, l'appareil d'amélioration de la qualité de l'eau ayant une structure simple et compacte, tout en étant facile à entretenir. La présente invention concerne également un procédé d'amélioration de la qualité de l'eau qui utilise cet appareil d'amélioration de la qualité de l'eau. La présente invention concerne un appareil d'amélioration de la qualité de l'eau conçu pour générer des ions superoxyde, l'appareil d'amélioration de la qualité de l'eau étant caractérisé par le fait qu'il comprend un récipient de traitement de forme ovale allongée qui est obtenu en formant, au moyen d'un treillis ou d'un matériau perméable à l'eau doté d'une pluralité de trous laissant passer l'eau, une paroi externe ovale allongée perméable à l'eau dont le diamètre est plus grand autour de la circonférence externe d'un corps flottant qui est en mesure de flotter dans l'eau, tout en formant un compartiment de stockage de matériau d'amélioration de la qualité de l'eau en séparant l'espace entre le corps flottant et la paroi externe perméable à l'eau de manière à stocker des billes de céramique fonctionnelles dans le compartiment de stockage de matériau d'amélioration de la qualité de l'eau séparé ; et un corps de corde de raccordement qui est fixé au récipient de traitement. La présente invention concerne également un procédé d'amélioration de la qualité de l'eau qui utilise cet appareil d'amélioration de la qualité de l'eau.
