Abstract

a. Turbine flottante pour l'aération des liquides, notamment des eaux usées. b. Cette turbine qui comprend un flotteur pourvu d'une ouverture centrale entourant un conduit d'aspiration dans lequel est prévu un impulseur entraîné par un moteur situé au-dessus de l'ouverture centrale, se caractérise en ce que le moteur est fixé sur un support comportant une embase annulaire prenant appui sur la face supérieure du flotteur, et en ce que le conduit d'aspiration porte sur sa face externe des moyens de pontage maintenus contre la face inférieure du flotteur, l'embase annulaire du support et les moyens de pontage étant reliés de façon amovible par des moyens de liaison passant entre le conduit d'aspiration et la face interne de l'ouverture. c. Traitement des eaux usées.
