Mass transfer of ozone in purified water

الملخص EN

This work presents the study of ozone mass transfer in water in bubble column with 0.5 cm 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 0.018-0.036 min-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.
