Both Ozone and UV are well recognized methods for  municipal drinking water treatment and disinfection.    Each can be used for the inactivation of viruses, giardia, cryptospordium, bacteria and other microbial contaminants.   While UV is limited to disinfection, ozone is also an effective treatment for taste, odor and color removal, iron and manganese reduction, as well as being a flocculating agent.

Ozone and/or UV require a relatively short residence times for disinfection unlike chemicals such as chlorine and chlorine derivatives.
