Abstract
Dispositif d'aération de liquide. La pompe centrifuge basse pression 14 refoule dans le collecteur 16 qui alimente les injecteurs 18, le mélange gaz-liquide étant envoyé dans les diffuseurs 8 et les chambres de mélange 23 pour revenir au réservoir par les déflecteurs 24. Moyennant un dimensionnement approprié l'on obtient une forte interphase gaz-liquide avec une faible dépense d'énergie. Application à l'oxygénation des eaux polluées.
