Précautions
La résine doit être conservée à l'état humide. La température idéale est supérieure à 0 °C. En cas de non-utilisation prolongée, il est conseillé de la conserver dans un endroit fermé ou d'ajouter de l'eau salée à 5 % ou plus. Un antigel est recommandé pendant le transport. Ne pas poser d'objets lourds sur la résine afin de ne pas la heurter.
Le traitement nécessite généralement un circuit d'écoulement alcalin-eau-acide-eau. Trois cycles sont nécessaires avant d'atteindre le canal d'ions final.
Il faut tenir compte des différents taux d'expansion de transformation pour réserver suffisamment d'espace pour éviter le débordement de résine et garantir la hauteur de niveau de liquide appropriée ; le rapport de diamètre de la colonne doit être dans une plage raisonnable et éviter le courant de polarisation ; utiliser une colonne remplie d'eau ou un rinçage à contre-courant pour éliminer les bulles à l'intérieur de la couche de résine.
Avant que le liquide ne pénètre dans la colonne de résine, des étapes telles que la floculation, la filtration ou la filtration sur sable doivent être effectuées afin d'éviter que les pores de la résine ne soient obstrués par des solides en suspension.
La résine à l'intérieur de la colonne qui n'a pas été utilisée depuis longtemps doit être stockée à l'extérieur de la colonne après lavage, ou ajout d'eau salée dans le milieu résistant au sel tout en gardant le niveau de liquide non déshydraté avec un lavage à contre-courant habituel pour détacher la résine en cas d'agglomération.
