Deionised Water – What Are the Different Uses?

By Martinez

DL water or Deionised Water is one type of water that has got the ions removed. Generally, the tap water is filled with ions that make it practical for some uses. For the normal water to get deionised, it needs to go through the ion exchange procedure. Let us know what is deionised water and why is it essential?

What will it get used for?

This kind of water is much purer than the distilled water that makes it ideal for the laboratory and the industrial applications. But, it also can be used domestically. For some instances, the normal water and distilled water will affect biological or mechanical functions; the Deionised water, due to the purest form, will not. There’re six primary uses of the deionised water that are given below.

Car Engines

Such kind of water is used commonly to the lead-acid batteries as well as engine’s coolant system. As water is free from ions, it can lengthen lifespan of this battery & coolant system. While if the normal water gets used, it will shorten the battery lifespan and make coolant system very rusty.


Suppose marine life is flourishing, then regular water will not get used in the fish tank. Since it is totally impure and will result in the unwanted algae developing. Lots of people make use of deionised water due to the high quality that will improve overall health of fish and make them perfect for using within the fish tank.

Laboratory Tests

To get right results, the ordinary water isn’t used in the lab tests. But, deionised water is generally used as it doesn’t impact its result. It is also used for cleaning instruments.

deionised waterIndustrial Machinery

To avoid grime and dirt from building up, this has to be cleaned on the regular basis. The regular water might lead parts of machinery to corrode very quickly that will make this pointless to clean, as purpose of this is avoid properties, like salt, to build up. The deionised water can be used for cooling; lubricating as well as manufacturing some products as it won’t make the parts of machinery corrodes very quickly.

Fire Extinguishers

The deionised water can be used in the fire extinguishers as it has the low electronic conductivity. That will make it very secure to use when fire around the electrical equipment is put out. This will, put out fire as well as not damage equipment, not like normal water.
