Il s’agit d’un proc\u00e9d\u00e9 chimique<\/strong> bas\u00e9 sur la capacit\u00e9 de r\u00e9sines synth\u00e9tiques pour fixer les cations et anions, en lib\u00e9rant de l’eau \u00ab\u00a0d\u00e9min\u00e9ralis\u00e9\u00a0\u00bb.<\/strong><\/p>\n\n\n\n

Comment fonctionnent les syst\u00e8mes de d\u00e9min\u00e9ralisation des r\u00e9sines<\/h2>\n\n\n\n

La technologie des d\u00e9min\u00e9ralisateurs repose sur les propri\u00e9t\u00e9s chimiques qui caract\u00e9risent les r\u00e9sines \u00e9changeuses d’ions, matrices polym\u00e9riques d’origine synth\u00e9tique.<\/p>\n\n\n\n

Ces r\u00e9sines sont pourvues de groupes fonctionnels actifs, ancr\u00e9s \u00e0 la matrice, capables d’\u00e9changer leurs ions mobiles avec des ions de m\u00eame charge contenus dans les solutions avec lesquelles elles entrent en contact.<\/p>\n\n\n\n

En pratique, gr\u00e2ce \u00e0 la d\u00e9min\u00e9ralisation de l’eau, les sels dissous sont retenus et permettent l’\u00e9puration partielle ou totale des effluents dilu\u00e9s ou concentr\u00e9s.<\/p>\n\n\n\n

D\u00e9min\u00e9ralisation de l’eau : La technique d’\u00e9change d’ions<\/h2>\n\n\n\n

La technique d’\u00e9change d’ions est largement utilis\u00e9e dans le domaine de l’\u00e9puration<\/strong> et dans le traitement des eaux primaires et est particuli\u00e8rement adapt\u00e9e \u00e0 la d\u00e9min\u00e9ralisation<\/strong>.<\/p>\n\n\n\n

De mani\u00e8re g\u00e9n\u00e9rale, les principales applications des syst\u00e8mes d’\u00e9change d’ions concernent:<\/p>\n\n\n\n

  1. Adoucissement de l’eau<\/strong><\/li>
  2. Production d’eau d\u00e9min\u00e9ralis\u00e9e<\/strong><\/li>
  3. Recyclage des eaux de lavage<\/strong><\/li>
  4. \u00c9limination<\/strong> des m\u00e9taux lourds<\/a> ou des substances ind\u00e9sirables<\/li><\/ol>\n\n\n\n

    Pourquoi choisir un syst\u00e8me de d\u00e9min\u00e9ralisation<\/h2>\n\n\n\n

    Les installations de d\u00e9min\u00e9ralisation avec technique d’\u00e9change d’ions sont particuli\u00e8rement utiles et avantageuses \u00e0 plusieurs \u00e9gards:<\/p>\n\n\n\n

    • production d’eau de meilleure qualit\u00e9 qu’un syst\u00e8me membranaire<\/li>
    • consommation d’\u00e9nergie r\u00e9duite<\/li>
    • il n’y a pas d’eau \u00e0 drainer (sauf pour les \u00e9luats produits lors de la r\u00e9g\u00e9n\u00e9ration)<\/li>
    • interventions de maintenance minimales<\/li>
    • id\u00e9al pour l’op\u00e9ration de recirculation sur les lignes de lavage finales dans les tunnels de pr\u00e9traitement<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"
