We assessed the performance of the combination of oxidation (ozonation or advanced oxidation processes, AOP) and ion-exchange treatment for better drinking water quality, especially with respect to chlorine consumption and chlorinous odor. In this process, dissolved organic matter (DOM) is converted to ionic species, and organic ions and ammonium ion are effectively removed during ion-exchange processes. We found that each treatment step (e.g., oxidation alone or ion exchange alone) was effective for the reduction of chlorinous odor to some extent, but the chlorinous odor formation potential was lower when AOP and ion exchange were applied in series. Also, DOC and ammonium ion were effectively removed with this combination. The effectiveness of this process was also confirmed in continuous mode with plot-scale experiment even without granular activated carbon treatment (GAC).
