Retrofitting Existing CIP Systems: All CIP systems have unique differences that must be taken into consideration when integrating an ozone system. A qualified ozone professional should be consulted to ensure smooth integration and satisfactory results.
Ozone Mass Transfer: Must be simplified and efficient. A venturi plus mass transfer tank generally works well. Controls: Interface with existing facility/CIP controls.
Facility Layout: Ozonated water can be pumped directly into existing CIP skid tanks to replace traditional sanitizer.
- Distance of Piping
- Evaluate ozone decay due to system design
- Monitor ozone levels on return to skid to assure appropriate CT (microorganism kill) values
Compatibility of Materials with Ozone: Verify compatibility of materials directly exposed to ozone, e.g., pump seals, elastomers, valve seats, plastic components, etc.
Ozone Off-Gas Management: The pressure drop across high-energy, impinging spray ball heads typically strips ozone gas out of solution and fills system with high concentration ozone gas. This is beneficial for disinfection, but a safety concern. Tanks and lines should be air-purged through a high-capacity ozone destruct device to clear excess ozone gas.
- Worker Safety
- Ozone system must include ambient ozone monitoring system with safety interlock
- Individual ozone monitoring systems for personnel should be considered
