The Ion Exchange Process The untreated water is passed through a bed of resin containing Cation resin in the "HYDROGEN" form and Anion resin in the "HYDROXIDE" form. When these impurities come in contact with the resin beads an "EXCHANGE" takes place, I.E. an aluminum ion will come in contact with a Cation bead.
"The mixed-bed attracts salts and trace elements, and binds these to the resin. Multistage regeneration cuts the knots and restores the resin’s capacity to demineralize" At that point the bead will accept the aluminum ion and will release a hydrogen ion. (Thus the term "Exchange"). Similarly, a chloride ion will come in contact with an Anion bead. At that point the bead will accept the chloride ion and will release a hydroxide ion. The combination of these two exchanges, one hydrogen (H) and one hydroxide(OH) produces "pure" water to operate the machine (H2O)
