The function of anion exchangers, cation exchangers and the role of the CO₂ trickling filter

Ion exchangers are indispensable components in water treatment. They specifically remove dissolved ions from the water and adapt its quality to a wide range of requirements - whether for industrial processes, the production of demineralized water or the recycling of process water. In this article, we explain how cation and anion exchangers work, which ions can be removed by the different types of resin and when it makes sense to use a CO₂ trickle filter.
