Deionized Water Harms and Benefits

There are many distinct types of water, including alkaline water, filtered water, purified water, dionized water aka DI water and tap water. Although most are acceptable to drink, they are typically unsuitable for uses where water is used as a rinse, component, or solvent. In actuality, ions like sodium, calcium, iron, copper, and other naturally occurring elements found in soil are present in water that comes from your faucet or other sources. Even though these chemical ions support the health of our organs, they frequently contaminate, interact with, and cause other issues in delicate industrial and home operations.  Ions in water can make it difficult to sterilize apparatus, clean glassware, conduct research in the lab, and perform other tasks. It is necessary to eliminate these ions from the water prior to application in such circumstances.

It is necessary to eliminate these ions from the water until use in such circumstances. Fortunately, there is easy solution deionized water.  However, what exactly is deionized water and how is it produced? What are the advantages and disadvantages of utilizing this kind of water? Drinking is safe, right? In this blog, we present the information.

Deionized water: what is it?


Water that has had all or the majority of its ions eliminated, typically using an ion-exchange procedure, is known as deionized water known as DI water or demineralized water. As we move on to the following section, please remember that ions are particles having either a positive or negative electric current.

How is Deionized water produced?


The process of creating DI water involves passing the groundwater via one or more electric charged polymers. To eliminate organic material and the majority of other impurities that might be present in the water, reverse osmosis (RO) is often used to filter the water before it is passed through the DI system. Prior to deionization, this pre-filtration step renders the water reasonably clean. The pre-filtered water is passed through two different kinds of ion-exchange polymers before it enters the DI system. There is a cation resin that contains positive ions and an anion resin that contains negative ions. A single combined ion-exchange polymer surface including both anions and cations is used by certain DI systems, though.

Hydrochloric Acid (HCI) is utilized to rebuild the cation bond in order to make DI water. The oppositely charged cation bead is next joined by the positively charged hydrogen (H+). Sodium hydroxide (NaOH) is used to renew the anion resin, the negatively charged Hydroxyl (OH-) bonds to the positively charged anion resin bead. However, not all ions have the same bonds some have stronger bonds than others. For example, calcium and sodium have a stronger binding between the cation resin beads. Ion exchange is possible because the H+ on the cation resin bead and the OH- on the anion resin bead do not have a deep attachment to the particle.

Consequently, the cations are converted into hydrogen (H+) as positive ions pass through the cation resin beads. Similar to how negatively charged anions exchange for hydroxyl as they pass through anion resin beads (OH-). Clean H2O is created when the ions H+ and OH- come together. The resin beads need to be regenerated in order to make them usable once more once all the exchange procedures on the cation and anion resin beads have been utilized up and the container is no longer producing DI water.

Water Deionization Methods


Deionization procedures come in three different varieties.


  1. Co-current deionization uses the conventional down flow method. Both the intake water and the regenerated compounds enter the top of the ion-exchange section and escape at the bottom in this procedure.
  2. Water flows from the top of the deionization process while regenerate chemicals flow from the bottom, or vice versa. Counter-current deionization takes lesser duration for the restoration than co-current deionization, which leads to the usage of fewer regenerates and reduced expenses overall.
  3. In a single ion-exchange phase, cation and anion resin are split 50/50 during mixed-bed deionization. The best grade purified water is normally produced by this procedure, but it is generally more costly than the other two.


The Benefits of Deionized Water


Deionized water may be a wise choice, based on the location and purpose of use. The following are a few advantages of DI water:


  • Some of the purest water that is available to humans is DI water. It is understandable why many producers in many industries choose it as their preferred water to prevent machinery damage from corrosion, build-up, and contamination from food, beverages, medications, cosmetics, and other goods.
  • Because the minerals have been taken out, DI water does not interact with metals in a way that causes corrosion.
  • No deposit is left behind when demineralized water dries up because it doesn't contain any pollutants. Additionally, calcification and mineral deposits are reduced.
  • DI water will not really conduct current very well because it contains few or no ions. In circumstances where highly conductive water might cause harm and interference, this feature is crucial.
  • Deionized water makes for a superior solvent. It facilitates blending different substances without include minerals that can contaminate the mixture or create issues when used.
  • Producing DI water quickly is possible despite deionization's complexity compared to other methods for producing different types of water.

Using Deionized Water May Be Risky


  • Insufficient or non-existent calcium, magnesium, and other nutrient intake: Despite calcium, magnesium, and a number of other essential minerals are not found primarily in water, a shortage of them in DI water may increase people's risk of under nutrition. One may experience premature birth, heart problems, and fracture if their dietary demands aren't satisfied from the foods they eat every day, as the majority of modern diets don't contain enough of these minerals.
  • Impact on the mucosal surface of the small intestine, metabolism, mineral balance, and other bodily processes: It has been convincingly shown that drinking water with little mineral composition interferes with homeostasis processes and jeopardizes the body's ability to regulate its mineral and water balance.
  • Demineralized water is quite abrasive, which may result in higher dietary hazardous metal consumption. This implies that it affects the pipelines and storage facilities used to distribute water, causing metals to leak into the water and increasing the amount of harmful metals you consume. Containers composed of plastic monomers and comparable materials may also leach plastic when exposed to DI water.
  • DI water is thought to be less effective at slaking thirst. That may be the case because the water lacks the electrolytes necessary to replenish the ones lost through perspiration and urination.
  • Fluoride is added to water supply systems to prevent dental cavities and other dental issues, which increases the risk of tooth harm. However, since fluoride is lost during deionization, cavities may develop if oral hygiene practices are not followed.
  • It really doesn't taste the same: DI water is regarded to have poor taste qualities since it loses the particles that give the water its flavor. Some claim that it tastes blander and less delicious than ordinary water. Even though it did not result in any burns or disintegrate any tissues in their mouths, several people also claim that it feels odd and prickly on the tongue. In light of this, you might feel compelled to seek out other, unhealthy beverages like soda.

Is it advisable to consume deionized water?


Although drinking DI water after deionization isn't always dangerous, it's important to remember that the procedure merely eliminates the ions. In this method, bacteria and viruses are not eliminated together with other pollutants. Additionally, even though purified water from a public supply is typically used to create DI water, the water might leach toxins from outdated pipes and transport them into your glass bottle. Therefore, we do not advise drinking DI water until you install a home filtration system to enhance the water's quality. Even if you drink it, you run the risk of dehydrating yourself and getting water that tastes odd.

Final Reflections


There are no mineral ions in deionized water. While its special quality makes it perfect for some uses, drinking it might not be advised. It works well in scientific studies, food preparation, aesthetics, cooling equipment, and other applications. Nevertheless, DI water is caustic in addition to lacking minerals. Additionally, it may harm sensitive tissues and teeth enamel. Deionization does not also eliminate germs. Therefore, it might not offer protection from infectious infections. Our home water systems, fortunately, are made to bridge this gap and provide you and your family with safe drinking water at house.
