Is Ozone Testing Required During Bottled Water Production? What Are The Typical Values?

Ozone concentration testing is required during bottled water production, with residual ozone concentration being the primary indicator. According to national standards, the ozone dosage and residual standards during bottled water treatment are as follows:

Necessity of Testing

As a disinfectant, ozone effectively kills microorganisms like bacteria and viruses. However, excessive residual levels may pose risks to human health and the environment. Therefore, real-time monitoring of ozone concentration during production is essential to ensure compliance with safety standards.

Concentration Standard Range

‌Final Product Water‌: Residual ozone concentration ≤0.3mg/L

‌Point-of-use water‌: Maintain a residual level ≥0.02 mg/L to ensure sustained disinfection efficacy ‌

‌Bottled water treatment‌: Typically requires a dissolved ozone concentration of 0.3–0.5 mg/L, with CT value (concentration × time) meeting disinfection requirements ‌
