Abstract

CUVE DE TRAITEMENT D’EAUX AVEC DES GOULOTTES DE GUIDAGE L’invention concerne une cuve de traitement d'eaux avec un axe vertical (Z) et comportant une cuve inférieure, une cuve supérieure (104, 204), une paroi horizontale (106, 206) percée d’orifices (116, 216) et disposée entre les cuves, une canalisation amont dirigeant un flux d’eau à traiter dans la cuve supérieure (104, 204), de manière horizontale et circulaire selon un sens horaire ou anti-horaire autour de l’axe vertical (Z), et pour chaque orifice (116, 216), la paroi horizontale (106, 206) est équipée d’une goulotte (250) avec une entrée coïncidant avec l’orifice (116, 216) et une sortie qui débouche dans la cuve inférieure, et qui dirige le flux d’eau de manière horizontale et circulaire et selon le même sens de rotation horaire ou anti-horaire autour de l’axe vertical (Z) que celui généré par la canalisation amont.
