Abstract
Cette invention concerne un procédé et un dispositif pour l'introduction de gaz dans des liquides. Il est prévu au moins un organe d'aération à axe horizontal monté sur un bassin et entraîné en rotation. Cet organe est constitué par un organe creux autoporteur éventuellement perforé et (ou) garni d'aubes, qui assure l'entraînement de gaz dans le liquide et qui longe partiellement dans celui-ci. La section d'écoulement du bassin au droit de l'organe creux présente un étranglement en forme de venturi. Ce procédé et ce dispositif sont applicables notamment à l'aération en surface des eaux d'égouts.
