Abstract

Ozonation has been widely applied in water treatment plants, so it is essential to figure out mass transfer and reaction kinetics in ozone contact tanks. In this study, a discrete-bubble model was established to calculate the dissolved ozone concentration in a countercurrent flow system. Results from batch experiments showed that an exponential relationship was well fitted between ozone reaction rate coefficient and ozone consumption amount, and the relationship was not affected by the ozone dosage. Therefore, it was applied in a discrete-bubble model, which was validated by experiments in a countercurrent bubble column with error less than 15%.
