Abstract
Appareil et procédé de dépôt par gravité de matières solides en suspension dans un liquide. On utilise un diffuseur de type particulier pour introduire, avec une faible turbulence, dans un bassin de sédimentation, un liquide contenant une suspension pouvant y floculer. La forme du diffuseur permet une diminution réglée de la vitesse de ce liquide. On y évite une rupture excessive des flocs, grâce au choix de l'angle d'évasement et du rapport entre la surface de décharge et une dimension du col permettant d'établir des conditions de faible turbulence et de formation de flocs. Application : clarification d'une eau résiduaire ou d'un liquide de traitement chimique.
