Which ozone application has the higher AOD range?

Which ozone application has the higher AOD range?

• A. Sterilization
• B. Microflocculation
• C. Both
• D. Neither

Answer: (A)

When deciding how much ozone to use, the goal drives the dose. Sterilization aims to inactivate a broad range of microorganisms, including tough pathogens, so it needs a stronger oxidative punch. That’s why higher ozone doses are used to ensure reliable disinfection. Microflocculation, on the other hand, is about destabilizing and removing particulates to permit coagulation and settling. It relies on forming larger flakes for removal rather than killing microbes, so the ozone dose required is much lower. Because of these different aims, sterilization uses the higher AOD range, while microflocculation does not.
