6.2.2.4. Ozone

• Ozone is a powerful oxidizer and sterilant.
• It is potentially harmful to fish, humans and most living organisms. It is definitely harmful to biofilters.
• It is used to improve water clarity and reduce disease transmission.
• Ozone should never be used directly before a biofilter.
• If ozone is used upstream of a biofilter, there should be sufficient retention time after the injection point to insure that no ozone residual enters the biofilter.
