Adsorption process by Powdered Activated Carbon(PAC) is regarded as an advanced drinking water treatment process, and thus the PAC adsorption process is performed with other conventional processes. In this study, the effect of chlorination on the adsorption capacity of PAC was evaluated. As a result, the capacity decreased when PAC contacted with chlorine. Furthermore, some part of contaminants once adsorbed onto PAC was desorbed by the chlorine addition to the bulk water. Adverse effect could be observed for the adsorption of cationic contaminants by use of coagulants and PAC. Successive addition of two different types of PAC was conducted and synergistic performance could not be obtained ; only additive effect could be observed.

粉末活性炭(PAC)吸附工艺是一种高级饮用水处理工艺，因此PAC吸附工艺是与其他常规工艺一起进行的。在本研究中，评估了氯化对PAC吸附容量的影响。结果表明，当PAC与氯接触时，容量下降。此外，部分污染物一旦被吸附到PAC上，就会被加氯到主体水中解吸。混凝剂和聚合氯化铝对阳离子污染物的吸附有不良影响。连续加入两种不同类型的PAC，不能获得协同作用，只能观察到相加效应。
