DI Filter :  removes Minerals by Ionic Attraction.


Q Explain Ionic Attraction ?


A H2O is two (1+) positively charged Hydrogen Molecules ionically attracted to one (2-) Oxygen molecule.  Minerals attach themselves to the water based on their ionic charge. For example, a Sodium molecule is (1+) and attaches itself weakly to the Oxygen molecule.  DI Resins are super-charged beads with half (+) charged and half (–) charged.  As the water passes slowly through the resin beads in the filter, the minerals are attracted to the super-charged of the resins, and ‘jump off’ the water molecules.  As a result, the water leaves the DI Filter ‘PURE’, with no Total Dissolved Solids (TDS ‘000’) – SPOT-FREE WATER !
