Ozone is a very reactive molecule, which rapidly initiates a chemical reaction when it comes into contact with other particles in the air or on surfaces. This process changes the molecular structure so that odour is no longer given off.
In seawater scrubbers, ozone can oxidise pollution in the dirty gas flow and on the walls. Odour can also remove pollutants from the water and prevent mussels and microorganisms adhering to surfaces in scrubbers and piping systems.
