NOM is known as precursors to produce disinfection by-products such as THMs and HAAs in drinking watertreatment. In this study, NOM removal and THMs reduction were investigated by comparing the conventionaland enhanced coagulation through jar-test. Additionally the efficiency of the coagulation was studied onactivated carbon adsorption using adsorption isotherms for natural waters. The experimental data weresimulated with IAST to investigate adsorbability of the NOM adsorption as multi-components isotherms. Theresults showed that enhanced coagulation could reduce 10 to 30% more of DOC and 5 to 20% more ofTHMs than those of conventional coagulation, respectively. The order of adsorption capacity on activatedcarbon showed that the enhanced coagulation had the highest capacity, the conventional coagulation andraw water. The order of adsorption capacity can be explained by increase of strong adsorbable fraction anddecreasing initial DOC concentration by enhanced coagulation.
