Deionization, commonly called DI, is complete demineralization of a water supply. Specifically, the term deionization is used with respect to the removal of the cations and anions from the water. In some cases, the water is passed through two separate columns of cation and anion resin. These days, most deionization is accomplished with the use of mixed-bed DI resin. DI water is similar to distilled water, and while it produces water that is pure in a ionic respect, it does not remove bacteria. Deionized water is commonly used in the following applications:
- Food Processing
- Car Wash Rinsing
- Industrial Processes
- Standard Mixed Bed DI Resin - Typically is for water up to 16 megaohms;
- Semiconductor Grade Mixed Bed Di Resin - Can deliver up to 18.2 megaohms; and
- Color Indicating Resin - Turns from blue to brown when it is exhausted and generally does not deliver much more than 10 megaohms.
