Ozone for Waste and Wastewater

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.

Oxygen vs Air for Ozone Production

The use of pure oxygen to produce ozone allows higher concentrations in the feed gas, which provides higher solubility

Less Energy Consumption

Pure oxygen provides direct costs savings against air in ozone production by reducing the required power by 2.5

Less Maintenance Costs

Pure oxygen is compatible with any ozone generator on which it provides longer life and savings on maintenance costs

Flexible Design

The use of pure oxygen delivers useful generation flexibility required in any water treatment process

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.
