| Abstract |
| Recently high levels of Geosmin and 2-MIB were increasingly detected in rivers. Limitation of treatment has appeared in general drinking water treatment process. In this study, removal efficiency was evaluated using advanced water treatment process and nanofiltration process. When the concentration of Geosmin and 2-MIB were below 500 ng/L, the permeate was 20 ng/L that the Minister of Environment recommends in nanofiltration process. And the removal efficiency was about 96% consistently over 500 ng/L. The removal efficiency was different according to various kinds of advanced water treatment process. After treatment, the 500 ng/L of Geosmin became below 10 ng/L by O3+GAC and the 1,000 ng/L of Geosmin became below 10 ng/L by O3/H2O2+GAC. After treatment, the 1,000 ng/L of 2-MIB became below 10 ng/L by O3+GAC or O3/H2O2+GAC. |
