在本系列的第一部分（哈斯和Karra，1984 b）中，综述了无需求系统中氯和氯胺灭活微生物的可用动力学信息。它的结论是，奇克沃森关系似乎是最令人满意的描述的失活process.In废水处理，在许多水处理厂的应用，这是不正确的，假设氯的需求是不存在的。这种需求的存在可以通过将游离氯转化为有机或无机氯形式来定性地改变消毒效率，或者可以通过减少存在的总残留量来定量地起作用。在过去，一些经验公式已被开发用于分析氯消毒的需求存在的情况下，可能存在于废水处理消毒。最广泛使用的模型似乎是由Selleck及其同事开发的模型（Selleck等人，1978年;白色，1972年）：
In Part I of this series (Haas and Karra, 1984b), The available kinetic information on the inactivation of microorganisms by chlorine and chloramines in demand-free systems was reviewed. It was concluded that the Chick-Watson relationship appeared to be most satisfactory for the description of the inactivation process.In wastewater treatment, and in many water treatment plant applications, it is incorrect to assume that the chlorine demand is absent. The presence of such demand may qualitatively alter disinfection efficiency by converting free chlorine to organic or inorganic chlorine forms, or may act quantitatively by reducing the total residual that is present. In the past, a number of empirical formulations have been developed for the analysis of chlorine disinfection in the presence of demand, as may exist in wastewater treatment disinfection. The most widely used model appears to be that developed by Selleck and associates (Selleck et al., 1978; White, 1972):
