Ozone (O3) is perhaps nature's most powerful purifier. It is widely used to purify drinking water because it is pH neutral, controls metals and destroys organic contaminates quickly with no residual chemicals remaining in the water. But despite ozone's great potency, nearly all systems on spas utilize designs that fail to address the critical components needed for successful water purification. These components are:
- Concentration of ozone: You must produce enough ozone at high concentration to purify and you must do so year after year without significant change in ozone output.
- Surface area: Large particles of ozone must be made smaller in order to increase the likelihood of reacting in solution.
- Contact time: The ozone must come in contact with the contaminates and have enough time to react.
