Single-step inactivation experiments with ozone and monochloramine revealed the presence of a CT lag followed by pseudo-first order inactivation kinetics. Sequential disinfection experiments with ozone followed by monochloramine revealed that ozone pretreatment resulted in the removal of a more prominent CT lag observed for monochloramine. In addition, the rate of inactivation for ozone-pretreated oocysts was approximately 2.5× greater than that observed for the post-lag phase portion of the monochloramine primary inactivation curve.
