Deionized water, also known as demineralized water (DI water or de-ionized water; can also be spelled deionised water), is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup. However, deionization does not significantly remove uncharged organic molecules, viruses or bacteria, except by incidental trapping in the resin. Specially made strong base anion resins can remove Gram-negative bacteria. Deionization can be done continuously and inexpensively using electrodeionization.

In water treatment the main processes used are demineralization, softening, ion exchange, gravity and pressure filtration. Trislot wedge wire screens are used in these processes to collect or distribute the treated liquid, to retain the treatment media, to filter solids. The main advantages compared to perforated plate, wire mesh or other filtration media are: high efficiency, long service life, flexible design, low maintenance.
