Demineralization is the removal of all cations (e.g. calcium, magnesium, sodium, potassium, Iron and other heavy metals) and all anions (e.g. bicarbonate alkalinity, chloride, sulfate, nitrate, silica and CO2) from a solution, typically water. The cations are replaced with H+ ions and the anions are replaced with OH- ions to form water. This reduces the total dissolved solids of the solution.

How does it work?
Mixed Bed Demineralization
There are many applications where the cation and anion resins can mixed together in a single vessel as a mixed bed. This configuration can be used for primary demineralization or as a polishing step following a two bed or multi-bed system.
