Deionized Water (also called DI water) is a type of purified water in which mineral ions are removed. Tap water is usually contaminated with different ions from the soil, pipes, or other sources. Some of these common ions include calcium, sodium, copper, iron, chloride, and bromide.
Deionization of water will also remove dissolved gases that may be in the water. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water include calcium, sodium, copper, iron, chloride, and bromide.
