Abstract
Cette invention concerne un rotor d'aération de surface destiné à être utilisé dans un réservoir rempli de liquide. Le rotor peut tourner sur un axe perpendiculaire à la surface statique du liquide. Il est équipé d'une pluralité de pales montées sur le bord inférieur d'un disque ou d'une surface de type disque. Chaque pale possède une géométrie courbe ou multi-facette allant de la verticale au point de fixation sur le disque à une inclinaison partielle à la partie inférieure. Les pales sont espacées sur la circonférence et font des angles aigus par rapport à des lignes radiales partant de l'axe de rotation du rotor. Les parties inférieures des pales, qui sont obliques et non verticales, sont disposées au niveau ou au-dessous de la surface statique du liquide. Lorsque le rotor tourne, la partie inférieure aspire le liquide le long de la partie verticale des pales où le liquide est vaporisé en gerbe vers le haut et vers l'extérieur par rapport au rotor. De par sa conception, le rotor de l'invention est beaucoup plus efficace en termes de transfert d'oxygène et de débits d'aspiration que les dispositifs actuels et convient tout particulièrement pour l'aération des eaux usées.
