The removal of all ionized minerals and salts (both organic and inorganic) from a solution by a two-phase ion exchange procedure First, positively charged ions are exchanged for a chemically equivalent amount of hydrogen ions Second, negatively charged ions are removed by an anion exchange resin for a chemically equivalent amount of hydroxide ions The hydrogen and hydroxide ions introduced in this process unite to form water molecules The term is often used interchangeably with demineralization
The removal of all ionized minerals and salts (both cationic and anionic) from a solution by a two-phase ion exchange procedure First, positively charged for a chemically equivalent amount of hydrogen ions Second, negatively charged ions are removed by an anion exchange resin for a chemically equivalent amount of hydroxide ions The hydrogen and hydroxide ions introduced in this process unite to form water molecules The term is often used interchangeably with demineralization
The removal of all ionized minerals and salts from a solution by a two-phase ion exchange process First, positively charged ions are removed by a cation exchange resin in exchange for a chemically equivalent amount of hydrogen ions Second, negatively charged ions are removed by an anion exchange resin for a chemically equivalent amount of hydroxide ions The hydrogen and hydroxide ions introduced in this process unite to form water molecules The term, commonly abbreviated as DI, is often used interchangeably with demineralization (See demineralization, ion exchange )
A process for filtering tap water before it is added to the aquarium It comes with either separate or mixed-bed resins The mixed-bed resins are disposable when they are exhausted, whereas separate resins can be recharged, though that requires working with caustic chemicals
The removal of all charged atoms or molecules from some material such as water For example, the removal of salt from water involves the removal of sodium ions (Na+) and chloride ions (Cl-) The process commonly employs one resin that attracts all positive ions and another resin to capture all negative ions Also see Capacitive DEIONIZATION ADVANCE \x 540
A return of the condition of the dielectric to a non-conductive state Failure to accomplish deionization because of inadequate flushing during off-time is sometimes responsible for DC arcing
Also called demineralization or ion exchange Synthetic resins are used to remove ions and minerals from feed water This is very effective at removing ionized impurities, but does not remove organic, bacterial, pathogenic, or particulate matter efficiently
