| The objective of this research was to investigate simultaneous removal of µg/L concentrations THMs and HAAs when UV/H2O2 is applied for removing ng/L concentrations geosmin and 2-MIB. 253.7 nm wavelength UV lamps and quartz reactors were employed with 6mg/L H2O2 for this purpose. Results showed that the UV/H2O2 process removes brominated THMs and HAAs faster than either only-chlorinated DBPs or geosmin/2-MIB at the typical concentrations found in drinking water. UV/H2O2 was also shown to completely eliminate brominated DBPs and partially reduce chlorinated DBPs at the same dose for removing geosmin and 2-MIB completely. These results demonstrate that UV/H2O2 could be used seasonally to control both DBPs and odorants simultaneously, especially in the region of high bromine concentration. |
