Ozone is a high-energy molecule. Its half-life in water at room temperature is only 20 minutes, and it decomposes into simple oxygen.

Dependent on the quality of the water, the half-life of ozone is in the range of seconds to hours. Factors influencing the decomposition of ozone in water are ...

When the half-life of ozone at 30°C is about 12 minutes, that means that every 12 minutes, there will be 50% less ozone in the water if we somehow inject the ...

Therefore, the half-life of ozone varies according to the type of water treated. For example, in typical drinking water it can be anything from 1 to 20 minutes.

At room temperature the half-life of ozone in water is about 15 minutes, while the half life of ozone in chilled water is closer to 30 minutes.
