Abstract

Tannic acid, as a surroguate of natural organic matter (NOM), were used as model compound. A study was conducted to evaluate the main disinfection byproducts of sequential use ozone and monochloramine to disinfection in the presence of tannic acid. Results of Disinfection byproduct formation potential show that the main disinfection byproduct include TCM (trichloromethane) and DCAA(dichloroacetic acid). Smaller anounts of TCAA(trichloroacetic acid) were also found. The production of TCM and DCAA increase significantly with the increase of disinfectant dosage(ozone and monochloramine)and temperature. From pH 7-8, more disinfectant byproducts are produced.
