Abstract

SYSTEME UTILISABLE EN PARTICULIER DANS LE TRAITEMENT DES EAUX. IL COMPREND UNE ROUE HELICOIDALE CREUSE 8 A AXE VERTICAL ENTRAINEE PAR UN MOTOREDUCTEUR ET TOURNANT DANS UN CORPS TUBULAIRE EVASE AUX DEUX BOUTS. L'EAU EST ASPIREE VERS LE BAS 4 DU BASSIN DE TRAITEMENT. UN COMPRESSEUR D'AIR PERMET D'INJECTER DE L'AIR DANS LA ROUE Y COMPRIS DANS LES AILETTES CREUSES 10, QUI SONT PERCEES D'UNE SERIE DE TROUS PAR LESQUELS L'AIR EST MELANGE A L'EAU. DES GAINES RADIALES D'EVACUATION SONT PREVUES DANS LE FOND DU BASSIN. APPLICATION AUX BASSINS D'ACTIVATION DE STATIONS D'EPURATION D'EAUX USEES ET A L'OZONISATION DE L'EAU.
