Applications of Deionized Water

Deionized water has been utilized in several applications in the research, industrial, and residential sectors. The deionization process removes charged mineral salts. This grants the water special characteristics, which can be taken advantage of in numerous ways.

Deionized Water for ScienceResearch science: Biologists and chemists prefer to limit the numbers of variables in their projects in order to reduce the amount of errors. They often rely upon deionized water when running experiments or creating buffer solutions. This limits the possibility of unforeseen interference, which can cause experiments to fail or results to be inconclusive.

Consumables industries: Bottled water companies, breweries, distilleries, food plants, and other industries related to consumable products rely on deionized water for their processing purposes. Purified water is necessary when meeting federally mandated chemical requirements. Deionized water is the perfect base stock for processing. Desired minerals and salts can be added to the water as needed.

Industrial boilers: Massive industrial boilers do not require a water supply that is free of mineral salts; however, the use of such purified water can lengthen their lifetimes. As boiler pressures increase, they require increasingly stringent qualities for the water they use. Deionized water fits these requirements handily.

Spotless Car Wash: In residential areas, deionized water has found a solid use in the cleaning applications. Because of the lack of mineral salts, a deionized water rinse will wash soap awaSpotless Car Washy without leaving spots. People who take pride in their automobiles enjoy having a spotless car wash. Furthermore, the windshields and paint jobs will not be damaged by regular exposure to impurities.

Window wash: Homeowners have begun making use of deionized water when cleaning their house’s windows and glass surfaces. The resulting spotless clean is only one benefit. The other is a lack of salt buildup over time, which can damage windows and glass shower doors. Hard water, water with an excess of mineral salts, can adhere to glass and etch it. This can lead to permanent damage unless it is regularly treated with mild acids such as vinegar. However, deionized water leads to a deep clean without any etching.

Deionization and Distillation Processes

While the deionization and distillation processes both result in purified water, they do so through different methodologies. Understanding those methodologies can reveal why each water type has its preferred applications.

Deionization is a chemical process that involves a removal of charged mineral salts. Water is a terrific solvent. When allowed the opportunity to sit in an area, such as wells or even city supply areas, it can collect charged particles such as copper, chloride, sulfate, and calcium. Each of these mineral salts has a low level negative or positive electrical charge. By exposing these charged salts to the proper conditions, chemists can induce reactions that will filter out these charged particles. This purifies the water, though it does not address uncharged particles or bacterial issues.

Distillation involves the boiling of a solution and then collection in a clean secondary container. This process is a physical one, which exploits the different boiling points for water and its impurities. Often distillation must be performed multiple times to result in the purest possible product.

    A problem with this explanation is that it does not tell us what are the typical deionized water solutes; nor does it inform us what range of ppm tds reduction we are likely to achieve with home type dionization resin filters.
    I believe that I could well use deionized water in place of RO water, but I would have to install the filters and test it to find out what quality of water remained, the pH and tds that could affect plants’ health.
    If somebody would recognize the orchids and rain forest plants growing businesses’ needs for good water and link that to some typical deionized water numbers, that would be mighty nice!
