Get To Know The Facts About Deionized Water

There is a lingering controversy regarding deionized water or distilled water. There are issues about the safety of this type of water. If you try reading some write-ups about pure water, you would find a few posts about mineral leaching. According to some speculations, water that does not contain ions can wash away ions in the body. Since minerals are absorbed by the body as ions, the leaching of minerals as allegedly caused by pure water can result to mineral deficiencies in humans.

However, this negative effect of deionized water is not backed up by enough scientific research to validate the claims. Manufacturers think that this could be part of campaign to impair the industry of pure water. The wrong information produces confusion among consumers.

Essentially, DI water is chemically similar to distilled water, as the latter does not contain ions too. So if water that has been deionized is not good for the body, then water that has been distilled is also not good for the body- but this is absurd.

According to experts if you drink DI water, it will quickly become re-ionized as it passes through the mouth down to the esophagus. What reaches the stomach is already re-ionized water. Let's assume this may affect ionic concentration of the body. It does, but to some insignificant degree. The body is an organic system with complex anatomy and complex mechanisms. The ionic makeup of the human body is not altered by simply drinking deionized or distilled water because the body's fluid composition is a buffered system. Some people thought that drinking water without ions hastens electrolyte loss through excretion. But the human excretory organs are guided by the body chemistry. Only the excess ions shall be excreted through urination. Drinking demineralized water does not remove ions that your body needs.

Deionization of water removes minerals to an extreme degree, but it does not make it unsafe and unhealthful. In fact, it can become effective in removing toxic chemicals in the body.

It is absurd to think that DI water can cause mineral deficiency because the body doesn't get minerals from water. Even if it is true that tap water contains minerals, the mineral content is insignificant in providing the recommended amount. You must drink tens of gallons of liquid to suffice for the mineral needs of the body. You get minerals from vegetables and meat, not from water. Nutrient deficiency is the result of wrong food choice not a result of drinking pure water.

Deionized or demineralized water is often subject to doubts regarding sanitation because according to some people, deionization removes ions only. While this is true, water deionization is simply a single process of an intricate technology of water treatment. Water treatment facilities don't subject water from reservoirs or from natural sources directly to deionization because this is one of the latter procedures. It undergoes filtration and treatment to remove sediments, solids, and microbes. Many water companies also include reverse osmosis treatment to remove large molecules, usually of organic and covalent substances, prior to deionization. If dirty water is fed to resin beds, it could easily spoil the deionization facility, causing larger cost for maintenance and regeneration of ion exchange beads.

So anyone who says that it is not pure does not really understand the complexity of water treatment. However, if you are unsure whether a company produces reliable DI water, you can have a sample tested for presence of contaminants.

The most significant importance of deionization is it removes all ions, including toxic metal ions and sulphates. Thus, it results to water with the most healthful quality. If you put a prime on hygiene and sanitation, DI water is the perfect choice.
