These resins are primarily used for water softening, the production of ultrapure water, wet metallurgy, and the separation of rare earth elements from complex solutions.
Resin should be kept in a wet state, preferably above 0°C. For long-term storage, it should be kept in a closed space or immersed in a 5% salt water solution.
It is highly recommended to implement pre-treatment steps such as flocculation, filtration, or sand-filtration to remove suspended solids before the liquid enters the resin column.
The resin is typically regenerated using 2BV of 3~5% HCl followed by 2BV of 2~4% NaOH to restore its ionic form and capacity.
Ensure the column diameter ratio is within a reasonable range and use wet packing or back-flushing to eliminate internal air bubbles that cause uneven flow.
Yes, the 001X7MB is designed to handle high-temperature operations with a maximum operating limit of 120°C.
