Abstract

L'invention concerne un appareil et un procédé permettant de dissoudre rapidement et efficacement des gaz dans un liquide. Un diffuseur (10), comprenant un dispositif creux (18) avec partie supérieure fermée, de préférence un tronc de cône creux (12) ayant une pluralité d'ouvertures (20) autour du périmètre proche de la partie supérieure fermée, est immergé dans le liquide et on le fait tourner à des vitesses relativement élevées afin de créer une centrifugeuse-pompe. Lorsque le diffuseur rotatif (10) est placé à proximité de la surface du liquide, aucun gaz supplémentaire n'est nécessaire dans le processus de dissolution. Lorsque le dispositif est immergé sensiblement sous la surface, ou bien lorsqu'on veut dissoudre un gaz autre que de l'oxygène, alors il est nécessaire de pomper du gaz dans l'ouverture inférieure du diffuseur rotatif. Ce dispositif peut être utilisé pour l'oxygénation d'eaux d'égouts traitées, pour l'élimination d'impuretés contenues dans des liquides, et pour l'oxygénation de pièces d'eau d'horticulture afin d'accroître la production.
