The DBP formation potential in UV/chlorine system may be
quite different from those during UV irradiation or chlorination
alone due to different reacting mechanisms. Recently, some
authors focused on the formation of DBPs in UV/chlorine process,
however, there is still limited understanding of the potential
effects of combined UV/chlorine on DBP formation [9,19].
Therefore, experiments were carried out to investigate the formation
of DBPs in different disinfection processes including UV irradiation,
chlorination and UV/chlorine in this study.
