What is Deionized Water? Complete Water Solutions

Deionized water has had virtually all of its dissolved mineral ions removed by ion exchange. It looks and handles exactly like tap water but behaves very differently — it has almost no conductivity, aggressively leaches minerals from anything it contacts, and is required in any application where dissolved ions would cause interference, scaling, or contamination.. What Is Deionized Water? Deionized water is water that has had most of its dissolved mineral ions removed, includingcommon ones like sodium, calcium, iron, copper, chloride, and sulfate. This is achieved througha process called ion exchange, where both positively and negatively charged ions areeliminated.

You may have heard that you needs to use either distilled or deionized water for one thing or another. But which one should you use and what's the difference?. Deionized water, often shortened to DI water, shows up anywhere tiny amounts of minerals could ruin a product, damage equipment, or skew a test. You see it in labs, semiconductor plants, hospitals, and even in some homes for car detailing or humidifiers. Yet many people are unsure what DI water really is, how it compares to distilled or RO water, and whether it is safe to drink.
