The Difference Between Deionized Water and Distilled Water

Comparing Deionized Water vs Distilled Water

When it comes to finding a water treatment solution for a business, and more specifically for any manufacturing application, it is important to develop the appropriate water treatment solution.

Having the wrong water treatment system installed could undermine the production throughout an entire facility, potentially costing a company copious amounts of time and money. Knowing the difference is likely a job better handled by water treatment experts.

There are some common keys to understanding the differences between the kinds of treated water and their respective treatment systems. Distilled water is the most common kind of purified water and may often be confused with deionized water, but the two are certainly different. Distilled water and deionized water are both fit to drink, but deionized water is more pure. Distilled water conducts electricity, whereas deionized water does not. This is critical in certain applications such as laboratory experiments.

Industries and Products That Use Deionized Water

  • Cleaning electronic devices
  • Cooling systems, such as ones used for laser welding
  • A/C fire extinguishers
  • Immersion cooling applications
  • Automotive applications
  • Electronical Discharge Machining
  • Pharmaceuticals
  • The beverage industry
  • Cosmetic products
  • Liquid detergents
  • Biochemistry applications

What Is Deionized Water Used For?

Deionized water can also be referred to as DI Water and simply means all the ions have been removed. This is important for applications where the highest purity water needs to be used. Deionized water has many applications where it is favored due to its high purity.

Deionized water is preferred in laboratory applications, as it is pure and won’t negatively affect test results. In industrial situations involving machining or high temperatures, deionized water helps by having low conductivity, and in turn, this helps lower the temperatures during manufacturing. Automotive applications, such as coolant systems, see the benefit of using deionized water by increasing the lifespan of the motor. The reason deionized water is preferred is due to its resistance to electricity from it not having charged ions to carry a charge.

Where You Can Buy Deionized Water

You can purchase individual containers of deionized water through a retail supplier. If you are a manufacturing facility or a laboratory in need of a distillation water treatment solution, finding a reputable water treatment company is your best option. Having a trusted supply of DI water can save you time and money, and will keep your operation running smoothly. The distillation process likely has to be custom-designed for your facility and having a reliable company to service your equipment can be just as important as the quality of industrial equipment you choose.
