Governing Standards for Chlorine Dioxide (ClO₂) Service
What to Avoid in Chlorine Dioxide (ClO₂) Service
- All carbon steel valves
- SS 316 valves for concentrated ClO₂
- NBR or EPDM-seated valves
Service Considerations
- ClO₂ is explosive above 10% v/v in air - on-site generation only, no bulk storage
- PVDF or titanium construction mandatory for all ClO₂ contact surfaces
- Emergency dilution water system required adjacent to ClO₂ generators
- NSF/ANSI 61 certification mandatory for drinking water ClO₂ dosing systems
