Abstract
L'invention concerne un procédé de régénération de résines échangeuses d'anions et de cations élimmant le risque d'influences perturbatrices provenant de la zone de résines mixte, la régénération s'effectuant dans des récipients indépendants du récipient de travail et après passage des résines épuisées dans un récipient séparateur 5 où les résines échangeuses d'anions 11 sont séparées des résines échangeuses de cations 12 par un courant d'eau ascendant (de 10 à 13) avec formation d'une zone mixte intermédiaire 6 soumise à divers traitements appropriés neutralisant son influence perturbatrice sur l'épuration des résines.
