While they are both attained through meticulous purification techniques, distilled and deionized water differ slightly in the purposes they serve. Learning about the treatment processes involved and the levels of purity they offer can help you make an informed decision. Below are some prominent features that set these two water types apart from each other.

How Distilled & Deionized Water Differ

Purification Process

Distillation involves heating the water to its boiling point and cooling the vapors down to get rid of soluble contaminants. Boiling kills off bacteria and helps separate water from the mineralized content. 

Deionization, on the other hand, involves treating water with positive and negative ions. These react with the free radicals from soluble minerals and help remove pollutants left behind after filtration.

Practical Use

Typically, distilled water is considered suitable for regular consumption, especially if it’s pretreated with water filters. This water also satisfies the purity criteria for laboratory tests.

In comparison, deionized water serves a variety of purposes in industrial and chemical use where ordinary tap water is not the right choice. It proves to be a great alternative to its distilled counterpart when it comes to laboratory experiments. Technicians also utilize it for cooling down overheated devices and equipment.

Cost Analysis

The expenses involved in obtaining each water type are also a point to consider when making a selection. Because distillation requires numerous steps, it can be more time-consuming. The reliance on heat and specialized equipment adds to the cost of performing this purification process.

In contrast, deionization typically delivers results at a much faster rate and results in lower costs compared to distillation. Since the procedure primarily depends on a chemical reaction, there’s no added expense for heating fuel.
