Abstract

Système pour échange d'ions utilisant une résine hétérogène, thermiquement régénérable. On réalise un traitement continu ou semi-continu dans une seule et unique colonne 2 contenant un seul lit de résine descendant reparti entre une zone de chargement froide 5, une zone-tampon thermique 4, maintenant un gradient de température, et une zone de régénération chaude 3. Elimination de sels à partir d'eaux industrielles, municipales ou ménagères dans des conditions efficaces et surtout plus économiques que lorsqu'on utilise les systèmes à deux colonnes.System for ion exchange using a heterogeneous, thermally regenerable resin. A continuous or semi-continuous treatment is carried out in a single column 2 containing a single bed of descending resin distributed between a cold loading zone 5, a thermal buffer zone 4, maintaining a temperature gradient, and a regeneration zone hot 3. Elimination of salts from industrial, municipal or domestic water under efficient conditions and above all more economical than when using two-column systems.
