영문 초록

The removal effect of odorous compounds due to algae in three water treatment plants was studied. A simple LLE-GC-MS-SIM procedure was used to the routine analysis of odorous compounds. We detected two odorous compounds of geosmin(GSM) and 2-methylisoborneol(2-MIB) in both raw and finished water. Concentration of 2-MIB and GSM ranged from ND to 12.5 and from ND to 66.0 ng/l in the raw and finished water, respectively. 2-MIB and GSM were not generally removed during conventional water treatment, but increased during chlorination owing to cell lysis. The flocculation or the filtration before the chlorination may be effective at reducing 2-MIB and GSM concentrations in the finished water throughout most of the season. Optimal coagulation agent, which does not cause lysis of cells of algae is necessary for the removal of cells in healthy state, with no additional release of GSM.
