The effect of water quality and NOM character on the ozonation of MIB and geosmin.
The ozonation of MIB and geosmin was studied in synthetic waters containing two natural organic material (NOM) fractions and sodium bicarbonate. The ozonation of both compounds was found to be affected by the character of the NOM fractions, with higher apparent rate constants observed in the fraction containing higher UV/visible absorbing properties. As the concentration of bicarbonate was increased, the destruction of both compounds decreased. MIB was found to be more resistant to ozonation than geosmin.
