Ozone can be added at several points throughout the wastewater treatment plant, such as pre-oxidation, intermediate oxidation or final disinfection.
Ozone is an unstable product that cannot be stored and needs to be produced on-site from oxygen through dedicated generators. Air Products as an oxygen major supplier has over the years developed the know-how to help its customers optimise the ozone processes.

What is the main benefit of using pure oxygen instead of air?
Pure oxygen uses higher ozone concentrations giving higher solubility and faster reactions. Pure oxygen ozonizers produce ozone concentrations in the range of 10-14% w/w.
Higher ozone concentrations equal higher treatments efficiency.
