Ozone is used in the treatment of water for the production of a wide range of consumer and/or pharmaceutical products. Ozone’s powerful oxidizing capacity, short residual, and minimal by-products make it ideal for disinfection in USP and WFI processes. Ozone provides a clean, safe temporal disinfectant residual within facility piping systems all the way to the application point without producing residuals or chemical by-products.


The most recent regulatory change to the Water For injection (0169)(WFI) monograph approves ozone when applied downstream of MF/UF/RO filtration. As a result, ozone treatment can now replace costly distillation processes in many USP or WFI applications. Because of its flexibility, ozone treatment can be easily adopted into most treatment processes.
