It is not uncommon to think that distilled and deionized water mean the same thing and it’s not uncommon to mix up what distilled and deionized water are. We want to clear that up because getting the two messed up can lead to some pretty horrific damages in the wrong context.
Comparing Distilled vs Deionized Water
Distilled Water: This water is boiled into a vapor and then that vapor is condensed back into a liquid in another container. This purifies the water because certain impurities do not boil and remain in the original container.
Deionized Water: With deionized water, which is often shortened to DI water, almost all of the mineral ions are removed. This is done through a chemical process that uses ion-exchange resins.
Two common types of treated water are distilled and deionized water. Here are some similarities and differences that are key to understanding them:
Both distilled and deionized water are fit to drink.
Deionized water is purer than distilled water.
Distilled water conducts electricity, while deionized water does not.
Industries That Use Deionized Water
Deionized water is used in more applications than you would expect. Many industries utilize deionized water. It is frequently used in manufacturing and chemical processing, among many others. A few examples include:
Automotive
Beverages
Biochemistry Field
Certain Fire Extinguishers
Cosmetics
Electrical Discharge Machining
Liquid Detergents
Pharmaceuticals
What Is Deionized Water Used For?
Due to being the highest purity water, there are certain situations where deionized water is commonly used. Here are some examples of some of the many applications where deionized water is needed or favored:
Laboratories: Since deionized water is pure, it won’t negatively affect test results.
Manufacturing: Due to all of the ions being removed, DI water has very low conductivity. This means that it’s a great option for industrial situations that involve machinery. Deionized water is also used in manufacturing to help lower temperatures.
Automotives: Deionized water is used as a coolant system to increase the lifespan of a motor. The reason DI water is used here is because of its resistance to electricity.
Medicine: There has to be a standard in medicine. That’s why these chemists have to use something called “water for injection”. The process of getting this water starts with creating deionized water.
Deionized water has unique properties which lead to it being used in unique situations. That’s why you see DI water appear in a wide range of situations and industries.
Technological Advancements in Deionized Water Production and Application
The realm of water purification, particularly deionized water, has witnessed significant technological advancements over the years. These innovations have not only made the production process more efficient but have also expanded the range of applications for deionized water.
