Abstract

Unité de traitement d'eau, comprenant une chambre de mélange qui entoure l'extrémité supérieure d'une colonne montante contenant une hélice. De l'eau peut être propulsée hors d'une masse d'eau vers le haut à travers la colonne montante, et sortir à travers des ouvertures orientées latéralement formées dans la chambre à proximité d'une entrée d'air. L'eau sort à travers les ouvertures orientées latéralement de la conduite verticale, se mélange avec l'air qui est aspiré à travers l'entrée d'air pour oxygéner l'eau, et l'eau oxygénée sort de la chambre dans la masse d'eau à travers une ou plusieurs sortie(s) d'eau prévue(s) dans la partie inférieure de la chambre sous l'effet de la charge hydraulique qui est développée par l'entrée d'eau dans la chambre. L'écoulement de sortie de l'eau en provenance de la chambre peut entraîner la formation d'un flux d'eau toroïdal ou d'un autre flux d'eau souhaité à l'intérieur de la masse d'eau qui entoure l'appareil de traitement d'eau.
