| Abstract | Geosmin and 2-MIB removals were evaluated with different empty bed contact time (EBCT) of 5, 10, 15min in granular activated carbon (GAC) columns at geosmin concentrations of 1000, 500, 100ng/L and 2-MIB concentrations of 300, 200, 100ng/L. As a result, GAC column with EBCT of 15 min displayed the highest removal of geosmin (89%) and 2-MIB (85%). With 5min EBCT increase, both geosmin and 2-MIB removal percentages increased 10-20%. In the NOM loading experiment, TOC were spiked in concentrations of 5, 10, 20 mg/L and evaluated through different EBCTs of 5, 10, 15 min. The result conformed that geosmin and 2-MIB removal efficiencies were significantly reduced in TOC concentrations of 5-10mg/L. At over 10mg/L of TOC loading, geosmin and 2MIB removals displayed below 40%. Therefore, at over 10mg/L of TOC, micropollutants could preload and block pores in GAC columns before geosmin and 2-MIB removal start. |
