Abstract

Turbine d'aération pour liquides et notamment pour l'épuration d'eaux usées soumises à un traitement de digestion par micro-organismes, du type comportant un disque pourvu sur sa face dirigée vers lesdits liquides d'un cône central dont le sommet est tourné vers le bas en étant immergé tandis que les pales de la turbine sont disposées sur la partie annulaire du disque définie entre la base du cône et la périphérie du disque, lesdites pales ayant sensiblement la forme d'un triangle raccordé par un côté à ladite partie annulaire du disque et l'angle oppose à ce côté étant immergé dans le milieu à brasser. Selon l'addition, cette turbine est caractérisée en ce que, en arrière d'au moins certaines pales par rapport au sens de rotation de la turbine, est prévu au moins un orifice traversant complètement l'épaisseur de ladite partie annulaire du disque, de façon que l'air aspiré à travers lesdits orifices, grâce à la dépression régnant du côté arrière des pales, est stocké sous la turbine, au centre de celle-ci, où il prend une forme de cône dont la pointe est dirigée vers le bas, ce cône d'air étant sensiblement coaxial au cône de la turbine. Epuration d'eaux usées.
