Pool gaseous ozone systems
The performance of Ozomax gaseous ozone pool and spa water treatment systems is independent of the water conductivity and hardness. Therefore, they are ideal for pools and spas where salt addition is not desired and/or for pools and spas that contain hard water (250 ppm CaCO3 or greater).
Ozomax Gaseous Ozone Pool treatment systems consist of three (3) components
Gaseous Ozone generator: Produces gaseous ozone from oxygen found in ambient air.
Air dryer: Removes humidity from ambient air before it enters the ozone generator. This increases the amount of ozone produced by the ozone generator and increases the life of the ozone generator.
Venturi (ozone injector): The venturi siphons air through the automatic vacuum air dryer and ozone generator and subsequently injects the ozone produced into the pool water recirculation stream.
How does ozone pool treatment work?
Ozone is injected and mixed into the pool recirculation water stream via the venturi. Once dissolved, ozone reacts with the cell membranes of bacteria and viruses, oxidizing them and converting them to carbon dioxide and water. Similarly, ozone oxidizes other pool water organic contaminants such as urine, sweat and saliva.
What model ozone generator do I need?
The size of ozone generator required is determined by the volume of your pool.
See sizing chart below.

Why do we need to use sodium bromide (NaBr)?
To further increase the solubility of the gaseous ozone in water without increasing the size of the ozone generator sodium bromide (NaBr), a naturally occurring component in sea water, can be added to the pool.
How much sodium bromide (NaBr) is needed?
Sodium bromide (NaBr) is added to the pool at a concentration of 15 - 30 mg/L (0.015 - 0.030 g/L) only at the beginning of the season.
Ozone (O3) reacts with sodium bromide (NaBr) to form hypobromous acid (HOBr) which itself is a powerful bactericide. Upon reacting with an organic molecule in the pool water hypobromous acid is converted back to bromide. This bromide then reacts with ozone to form hypobromous acid and the cycle begins again.
In this way, the sodium bromide is continuously recycled by ozone. So, one only needs to add 15 - 30 mg/L (0.015 - 0.030 g/L) at the beginning of the season and perhaps add 1-3 mg/L (0.001 - 0.003 g/L) every few months to make-up for losses due to backwashing, splashing, drag-out etc.
