Abstract

L'INVENTION CONCERNE UN PROCEDE INDUSTRIEL POUR ELIMINER DES IONS D'UNE SOLUTION AQUEUSE CONSTITUANT LA CHARGE D'UNE INSTALLATION. CETTE INSTALLATION COMPREND UNE COLONNE QUI CONTIENT UN LIT CONSTITUE D'UN MELANGE DE RESINES ECHANGEUSES D'ANIONS ET DE CATIONS. CE LIT PEUT MONTER OU DESCENDRE EN MASSE DANS LA COLONNE. LA SOLUTION DE CHARGE EST MISE EN CIRCULATION A TRAVERS LE LIT DE MANIERE A TENDRE A L'ELEVER, PUIS DES SOLUTIONS D'EPURATION, DE REGENERATION ET DE RINCAGE SONT MISES EN CIRCULATION EGALEMENT A TRAVERS LE LIT EN FORMANT DES COURANTS DESCENDANTS. DOMAINE D'APPLICATION: TRAITEMENT DE SOLUTIONS AQUEUSES RICHES EN CHLORATES PROVENANT DE L'ELECTROLYSE DE SOLUTIONS DE CHLORURE DE SODIUM.
