本研究的目的是研究在使用臭氧和游离氯或组合氯的连续消毒方案中微小隐孢子虫卵囊的失活动力学。使用臭氧作为主要消毒剂、游离氯或组合氯作为次要消毒剂的连续消毒实验表明，单独使用臭氧预处理可消除两种氯的更显著CT滞后。另一个好处是，臭氧预处理的卵囊的失活率明显高于单独使用游离氯或组合氯获得的失活曲线的滞后期后部分。包括8个参考文献，图。

The objective of this study was to investigate the inactivation kineticsof Cryptosporidium parvum oocysts in sequential disinfection scenarios involving the use of ozone followed by either free or combined chlorine. Sequential disinfection experiments using ozone as the primary disinfectant and free or combined chlorine as the secondary disinfectant revealed that ozone pretreatment resulted in the removal of a more prominent CT lag observed for both chlorine species, when used alone. An additional benefit was that the rate of inactivation for ozone pretreated oocysts was significantly greater than that observed for the post lag phase portion of the inactivation curves obtained with free or combined chlorine alone.
