Weak acid cation resins are primarily used for water softening, the separation and purification of biochemical drugs, and the recycling of precious metals like zinc and nickel from industrial waste.
Resin should be kept in a wet state above 0°C. For long-term storage, it should be kept in a closed space or submerged in a salt solution of 5% or higher to prevent dehydration and agglomeration.
The general flow path is alkali-water-acid-water. Recommended agents include 3-5% HCl (2BV) for desorption and 2-4% NaOH (2BV) for regeneration.
Yes, the D113 FG resin is food-grade and complies with FDA standards, holding national food hygiene licenses and WQA international certifications.
It is essential to implement pre-treatment steps such as flocculation, filtration, or sand-filtration before the liquid enters the resin column to remove suspended solids.
Color-changing systems allow operators to visually monitor the saturation level of the resin, enabling timely regeneration and preventing breakthrough, which minimizes downtime.
