Abstract
DISPOSITIF D'AERATION ET DE PROPULSION D'UN LIQUIDE CONTENANT DES MATIERES EN SUSPENSION ET CIRCULANT DANS UN BASSIN ENTRE UNE ENTREE ET UNE SORTIE. LES MOYENS DE PROPULSION COMPRENNENT UNE OU PLUSIEURS ROUES A AUBES, A AXE DE ROTATION VERTICAL, LES AUBES S'ETENDANT SUR AU MOINS UNE PARTIE DE LA HAUTEUR DU LIQUIDE. L'AXE DE ROTATION EST SITUE SENSIBLEMENT DANS LE PLAN D'UNE CLOISON INTERIEURE DEFINISSANT UN CIRCUIT FERME DU LIQUIDE DANS LE BASSIN. DES MOYENS D'ENTRAINEMENT, PLACES AU-DESSUS DU LIQUIDE, FONT TOURNER LA ROUE A UNE FAIBLE VITESSE, SUFFISANTE POUR OBTENIR UNE VITESSE LINEAIRE D'ECOULEMENT COMPATIBLE AVEC LE MAINTIEN DES SOLIDES EN SUSPENSION. L'AIR EST INTRODUIT PAR DES ORIFICES, DANS LE LIQUIDE DEPLACE PAR LES AUBES. L'INVENTION S'APPLIQUE A L'EPURATION BIOLOGIQUE DES EAUX RESIDUAIRES.
