Abstract

L'invention concerne un procédé de régénération externe de résines d'échange d'anions et de cations usées d'un filtre à lit mixte dans lequel les résines d'échange d'anions et de cations sont régénérées séparément. Après séparation, par un liquide ascendant, des résines d'échange d'anions 10 et de cations 9 usées, la zone mixte 11 intermédiaire aux deux précédentes en est séparée et ramenée à la masse de résine d'échange d'anions et de cations usée avant l'opération de séparation.
