Deionization (DI) is a chemical purification process that removes dissolved ions, or electrically charged particles, from water. This is done by neutralizing them with ions of the opposite polarity through a process called ion exchange. An ion exchange water filter contains electrically charged resins that attract the salts and ionic compounds in the water.
The DI process can be used to produce a very high quality of purified, demineralized water. Pure deionized water is neutral, with a pH of 7 and a high electrical resistance.
How Is Deionized Water Used?
Deionized water’s neutral qualities make it possible to create solutions with other substances without altering their composition. This makes it a cost-effective alternative to distilled water where an extremely high quality of water is desired. It is used extensively in biotech, manufacturing and in the medical industry as an ingredient in pharmaceuticals, in hospitals and for laboratory use.
Deionized water is also highly prized in manufacturing. In addition to its use as an ingredient in cosmetics, processed food and other products, it is often used in cleaning and lubrication processes to avoid corrosive salt build up on expensive equipment. Because of its low conductivity, deionized water is also useful as a cooling agent to keep lasers and other devices from overheating.
Some of the benefits of deionized water include:
- Improved ROI from manufacturing processes
- Reduced operating costs
- Compliance with industry standards
- Reduced downtime
- Improved product quality
It is important to note that a water deionizer system will not remove all impurities from water. Suspended particulate must be removed first with a pre-filter. Additionally, deionization does not significantly remove uncharged organic molecules, bacteria or viruses.
Your Deionized Water Experts
Each industry that uses deionized water must comply with that industry’s set of standards, which vary from industry to industry and are enforced by different professional organizations.
