Information on dissolved ozone in water.
On this page you’ll find information on dissolved ozone in water. For example, what is dissolved ozone? What does this value tell you and what does it depend on?
Ozone can dissolve in water just like oxygen can, even better than oxygen. The amount of dissolved ozone will reduce fast though, because ozone falls back into oxygen by itself. On the plus side, ozone will react with any pollution present in the water.
The maximum amount of dissolved ozone in water depends on a couple factors such as pressure, temperature, pH and a few more parameters. The temperature and pressure are the most important and influential ones.
If the ozone gas has a concentration of 100gr/Nm³, then about 30 grams of ozone can be dissolved per cubic meter at 20 degrees Celsius. This also shows the importance of a high ozone concentration. A high amount of dissolved ozone is only possible when the ozone concentration in the gaseous phase is high. Whether or not we want dissolved ozone in water, and how much of it, depends on the application.
Ponds
For a pond for example, we want little to no dissolved ozone in the water. This is why ponds need ozone reactors that are relatively big. The ozone has to be able to react somewhere else than in the pond. This is what the ozone reactor is used for.
Industry
In the industry, for example for disinfecting purposes, we want as much dissolved ozone in the water as possible. The more ozone present, the more effective the bacteria, dirt and such will be oxidised. It’s not always necessary to use a big ozone reactor where the application allows dissolved ozone to be in the water because the ozone can react with the pollution during the process. We do need to use an effective method for dissolving the ozone in the water. A venturi or HD ozone reactor can be used for this.
The text above describes the basics on dissolved ozone. In practice, a bunch of other different factors play a role as well. The influence pressure has isn’t mentioned for example, simply because that would take way too long to explain on a website.
