WebData are available for pH 7 and 9, and for 5° to 25°C. Ozone was the most effective agent. A 99% inactivation was attained at 5°C and pH 7.2 with a mean C-t of 0.2 mg/L • minutes. Ozone data are available for 5°, 10°, and 20°C, and for pH 7.0 or 7.2. A limited number of other data are also presented in the full report. WebStep 4 Identify the CT table for the log inactivation credit desired for each chamber. Calculate the ratio of CT calc to CT table, and sum the ratios to get a total log inactivation ratio.
