This work presents the study of ozone mass transfer in water in bubble column with
0.5cm inside diameter and 2 m height. The volumetric mass transfer, rate constant of
ozone decomposition and mass transfer efficiency were studied with different gas flow
rates (50,100, 150, 200, 250) L/min.
The volumetric mass transfer as well as rate of decomposition of ozone was found to
increase with increasing gas flow rate. They were ranged between 0.21-0.41min-1 and
0.018-0.036min-1 respectively.
Mass transfer efficiency was increased from 77 to 98% with increasing gas flow rate.
A mathematical model was numerically solved to describe the liquid ozone
concentration with time. The model and experimental results agreed well.
