Abstract

LA PRESENTE INVENTION CONCERNE LE TRAITEMENT DES LIQUIDES PAR FLOTTATION. ELLE PROPOSE UNE CELLULE DE FLOTTATION AVEC UNE CUVE VERTICALE, UN DISPOSITIF POUR PRODUIRE DES BULLES DANS LA CUVE, UN SYSTEME D'EVACUATION DE MATIERES SOLIDES, DANS LAQUELLE LA CUVE EST PARTAGEE PAR UNE CLOISON INCLINEE EN DEUX CHAMBRES QUI COMMUNIQUENT AU NIVEAU DE LA PARTIE HAUTE DE LA CLOISON, LA CHAMBRE BASSE DANS LAQUELLE SONT FOURNIES LES BULLES ETANT MUNIE D'AU MOINS UNE CANALISATION D'AMENEE DE LIQUIDE A TRAITER, LA CHAMBRE HAUTE ETANT MUNIE D'AU MOINS UNE CANALISATION D'EXTRACTION DE LIQUIDE CLARIFIE QUI PREND NAISSANCE A UN NIVEAU INFERIEUR A CELUI DE LA COMMUNICATION ENTRE LES DEUX CHAMBRES. LA PRESENTE INVENTION EST UTILISEE POUR CLARIFIER DES LIQUIDES CHARGES ET POUR EPAISSIR LES BOUES RASSEMBLEES EN SURFACE ET CONSTITUEES PAR LES DECHETS CHARGEANT INITIALEMENT CES LIQUIDES.
