What are ions in water?

Ions are electrically charged molecules, and are formed as pollutants dissolve in water. Natural areas of water have a balance of positively and negatively charged ions. Ions are what determine the TDS and conductivity of the water. The greater presence of ions results in higher TDS and conductivity.  

How does ion exchange water treatment work?

Ion exchange water treatment works by removing material from the water through the use of water processes such as water softening systems, and water deionization systems. These systems work by exchanging specific ions for other ions. When it comes to water softeners, magnesium and calcium ions are replaced by sodium ions. As for water deionization systems, the cations are exchanged for hydrogen ions, while the anions are exchanged for hydroxyl ions.
