Abstract

LE PROCEDE EST DU TYPE SELON LEQUEL ON FAIT PERCOLER DE HAUT EN BAS L'EAU A TRAITER A TRAVERS UN LIT SUBMERGE ET FIXE DE MATERIAU FILTRANT GRANULAIRE AVEC INSUFFLATION, A NIVEAU INTERMEDIAIRE, D'UN COURANT GAZEUX OXYGENE ASCENDANT. SELON L'INVENTION, LES DEBITS D'EAU A TRAITER ET DE GAZ OXYGENE SONT REGLES DE FACON A SATISFAIRE A UN CERTAIN NOMBRE DE RELATIONS QUI DEFINISSENT UNE LOI GENERALE ELARGISSANT NOTABLEMENT LE DOMAINE DE TRAITEMENT CONNU AU CHARBON ACTIF. LE LIT, GENERALEMENT A BASE DE C ACTIF, PEUT ETRE MULTICOUCHES AVEC DES COUCHES INFERIEURES DE SABLE ETOU ANTHRACITE. LA COMMANDE DE GAZ OXYGENE (AIR, OXYGENE, AIR OZONISE) EST REGULEE PAR SONDE DE MESURE. APPLICATION DU PROCEDE AU TRAITEMENT D'EAUX DE SURFACE OU DE NAPPES EN VUE DE LES RENDRE POTABLES AINSI QU'AU TRAITEMENT DES EAUX RESIDUAIRES COMME EAUX D'EGOUTS OU INDUSTRIELLES.
