As we explained in our website section on pool water disinfection and cleaning , there are different options for treating and disinfecting your pool water. Much has been written about the most well-known methods (chlorine and bromine), so we’re starting a series of posts to explain the lesser-known ones. Today we’re talking about pool cleaning and disinfection using ozone.
Ozone can be a substitute for chlorine and bromine , as it is a natural flocculant as well as a powerful algaecide, meaning it does not contain chemicals.

After disinfection, ozone converts to oxygen and therefore leaves no trace in the water. However, the water always needs a small amount of disinfectant, so since ozone has no residual effect, it must be used in conjunction with another chemical compound, such as chlorine. However, the amount of chlorine used will be only 5% of what would be used in a treatment without ozone.
The main benefit of disinfecting water with ozone is the near-total elimination of pool odor, red eyes, and skin and hair irritation, among other consequences associated with using products like chlorine. Furthermore, ozone not only aids in water disinfection but also acts as a coagulant, meaning it enhances the effectiveness of sand and activated carbon filters. Finally, this process contributes to water conservation since no additional water is needed for filter renewal.
Conversely, the disadvantage is that it is more expensive and more difficult to install. Furthermore, the process requires more space because the necessary machinery is larger than that used in other systems.
In summary, ozone is superior to components such as chlorine or bromine in terms of disinfecting capacity, low toxicity and water quality, but it is surpassed by these in terms of residence time. If your priority is to enjoy a healthy and comfortable bath, the best option is to use ozone, without forgetting the environmental benefit it brings.
