| Research Abstract |
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.
