Difference between ion exchange demineralization and ion exchange softening
Abstract：Ion exchange desalination is intended to remove all salt-forming ions in water, so it requires the simultaneous use of strong-acid cation resins and strong-base anion resins, rather than only salt-type resins. This is because although salt-type resins can remove the original salt-forming ions in water, they generate new salt-forming ions, leaving the salt content in water basically unchanged. To remove salt-forming ions in water, the combined use of strong-acid resins and strong-base resins is essential.
