United StatesEnvironmental ProtectionAgencyOffice of WaterWashington, 832-F-99-063 September 1999 WastewaterTechnology Fact SheetOzone DisinfectionDESCRIPTIOND isinfection is considered to be the primarymechanism for the inactivation/destruction ofpathogenic organisms to prevent the spread ofwaterborne diseases to downstream users and theenvironment. It is important that Wastewater beadequately treated prior to Disinfection in order forany disinfectant to be effective.
