Ozone for Waste and Wastewater

Ozone generation from pure oxygen for wastewater treatment (hard COD removal & biodegradability increase)

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 optimize 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 cost savings vs. air in ozone production by reducing the power requirement by 2.5x

Less Maintenance Costs

Pure oxygen is compatible with any ozone generator. It provides longer life and maintenance cost savings

Flexible Design

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