Ionized Water

Published: | Updated: November 22, 2016

Definition - What does Ionized Water mean?

Ionized water is natural water that has been run through an ionizer machine's platinum and titanium plates to exchange some of the titanium and platinum ions with the water, thereby increasing its alkaline nature and the pH level of natural water. This process also helps remove impurities from the water.

Ionized water is also referred as artificially alkaline water.

Corrosionpedia explains Ionized Water

Water that passes through stainless steel pipelines for drinking or industrial purposes must be maintained at specific pH levels. Water pH levels that are too low (acidic water) or pH levels that are too high (ionized water or alkaline water) will accelerate the corrosion process in metal pipelines and other infrastructure items.

Some factors that can lead to corrosion when ionized or highly alkaline water is present in the system include:

  • For highly alkaline water, a chemical scale may form that will help protect against corrosion, but if a bacterial scale such as sulfur reducing bacteria (SRB) becomes established then the system may experience a microbiologically induced corrosion (MIC) problem.
  • A very high flow rate of alkaline water in the pipe can cause physical corrosion.
