Ozone in Water Treatment Basics

Water Ozonation Secrets

Ozone Generators for Water Purification

Ozone is unstable and must be created at the time you wish to use it. It is so unstable, that 30 minutes after you have made it, only half of it remains. Where does the Ozone (O3) go? Nowhere, it simply turns back into Oxygen (O2). So, if you want to use ozone to ozonated your drinking water, hot tub, swimming pool, or use it for other purification procedures you need to make it yourself from oxygen.

If you are going to use ozone for water purification, you can usually get the oxygen from the air. Air is 78% Nitrogen, 21% Oxygen, and 1% trace gases (such as Argon).

However, some ozone applications might require that you make higher concentrations of ozone, which means you will need to start with higher concentrations of oxygen such as 100% oxygen from an oxygen tank. (Note: If you want to make Medical Grade Ozonated Water for Health Benefits, Burns, Sterilizing etc. you need to use purified oxygen, not air. See the article Ozonated Water). Oxygen tanks hold 99% pure oxygen and are available from either welding shops or through a prescription from your doctor. Bottled oxygen should only be used with ozone generators that were designed to be fed with purified bottled oxygen. Never try to feed your ozone generator with oxygen if it was designed to be fed with ‘air’ or the results could be disaster.

There are many different types of ozone generators available on the market today. They all make ozone using different technologies, and they all produce different amounts of ozone. Not every ozone generator will be able to do what you want it to do, so if you are shopping for an ozone generator make sure you are buying the proper type, and one that creates the proper amount of ozone. Each ozone application on this list requires different levels or concentrations of ozone:

You also need to think about how much ozone you want in the water. Do you want to just ensure that the bacteria and viruses have been killed in the water? Or do you want to ensure all of the volatile organic and possibly toxic compounds have been destroyed in the water? Perhaps you want both of those things to happen but you also want there to be ozone remaining in the water when you actually drink it? All three of these examples require different levels of ozone, ranging from relatively low levels of ozone coming from the ozone generator to very high levels of ozone.

There are many different reasons for ozonating water, and there are many different ozone generators on the market. Decide what you want to do with the ozone, then research your choice of ozone generators carefully before making your purchase.
