5. Precautions:
1. Transportation and Storage of the Product:
Store the product in a wet state, preferably above 0°C; if unused for a long time, keep it sealed or add more than 5% brine; during transportation, mainly prevent freezing, and do not place heavy objects on the resin to avoid crushing.
2. Resin Pretreatment:
Generally, a process of alkali-water-acid-water can be used; for strict requirements, three cycles are needed, finally treating the resin into the required ionic form.
3. Resin Loading:
Consider the resin's swelling rate during ion exchange, reserve enough space to prevent overflow and ensure proper liquid level; the column diameter ratio should be reasonable to avoid channeling; use wet loading or backwash to remove air bubbles inside the resin bed.
4. Before liquid enters the resin column, it should undergo flocculation, filtration, or sand filtration to ensure no suspended solids, preventing blockage of resin pores.
5. Resin unused in the column for a long time must be cleaned and removed for storage, or kept in a salt-resistant medium with brine, maintaining the surface moisture and periodically backwashing the resin to loosen it and prevent caking and spoilage.
