Abstract
PROCEDE DE REGENERATION DE RESINES ECHANGEUSES D'IONS. IL COMPREND LA SEPARATION DES RESINES PAR LAVAGE A CONTRE-COURANT, LE PASSAGE D'UNE SOLUTION REGENERATRICE ANIONIQUE SUR LA COUCHE DE RESINE ANIONIQUE, LE PASSAGE DE CETTE SOLUTION REGENERATRICE SUR L'ENSEMBLE DES DEUX COUCHES ANIONIQUE ET CATIONIQUE, ET ENFIN LE PASSAGE D'UNE SOLUTION REGENERATRICE CATIONIQUE SUR LA COUCHE DE RESINE ECHANGEUSE DE CATIONS. CE PROCEDE SERT A L'ELIMINATION DE LA SILICE POUR LA REGENERATION DES RESINES UTILISEES DANS LES TRAITEMENTS DES EAUX INDUSTRIELLES. ON PEUT ABAISSER LA TENEUR EN SILICE DANS L'EAU TRAITE JUSQU'A MOINS DE 0,01MILLIGRAMMELITRE.
