I'm trying to find out what other companies are doing regarding the frequency of sanitizing the water loop. Specifically an ambient DI/RO system which feeds into a Hot DI/WFI system.
We are suggesting, as a quality unit, quarterly but being offered every 6 months.
If you can answer in terms of chemical sanitization that would be appreciated.
