Abstract

PROCEDE DE FILTRATION POUR L'ELIMINATION DE L'AMMONIAQUE DES EAUX CONTENANT UNE QUANTITE D'AMMONIAQUE INFERIEURE A 20MGL, EN PARTICULIER DES EAUX DESTINEES A L'ALIMENTATION, DANS LEQUEL L'EAU A TRAITER EST AMENEE A TRAVERSER DE BAS EN HAUT AU MOINS UN LIT DE MATERIAU GRANULAIRE ENSEMENCE EN MICRO-ORGANISMES BACTERIENS, AVEC APPORT D'OXYGENE, CARACTERISE EN CE QUE L'APPORT D'OXYGENE EST EFFECTUE DANS LE COURANT D'EAU A TRAITER AVANT SON INJECTION DANS LE LIT DE MATERIAU GRANULAIRE, CE QUI PERMET UN DEGAGEMENT D'OXYGENE SOUS FORME DE BULLES ENTRAINEES PAR LE COURANT D'EAU A TRAVERS LA MASSE FILTRANTE SUR TOUTE SA HAUTEUR.
