臭氧氧化工艺仍然是水厂一个有吸引力的处理选择。根据《安全饮用水法》，公用事业公司必须满足《地表水处理规则》规定的消毒要求（累积CT积分），同时满足卤化消毒副产品的监管限制。公用事业公司可以使用臭氧作为主要消毒剂，从而减少二次消毒所需的氯量，并相应地减少消毒副产品的形成。到目前为止，还没有成熟的模型来预测臭氧气液接触器中液相的臭氧浓度，以满足臭氧初级消毒的CT要求。这项工作是研究臭氧接触器中的传质、反应和扩散的研究项目的一部分。

Ozonation processes continue to be an attractive treatment option for water utilities. Utilities are required to meet the disinfection requirements (accrue the CT credits) mandated by the Surface Water Treatment Rule while meeting the regulatory limits on halogenated disinfection byproducts in accordance with the Safe Drinking Water Act. Utilities can use ozone as a primary disinfectant, thereby reducing the amount of chlorine required for secondary disinfection, and correspondingly lowering the formation of disinfection byproducts. To date, there are no well-established models for predicting the concentration of ozone in the liquid phase in ozone gas-liquid contactors in order to meet the CT requirements for primary disinfection by ozone. This work is part of a research project studying mass transfer, reaction, and dispersion in ozone contactors.
