Evaluating Water Ozonization Process in Several Bubble Columns M. Bataller, E. Rus(1), P. Martínez(1), R. Pérez-Rey. Ozone Research Center, Cuba. 1 - Faculty of Science, Malaga University, Spain. This paper presents the water ozonization process evaluation in bubble columns considering mass transfer parameters and the effect of chemical reaction on the mass transfer rate, which was obtained for different water qualities. Determination of Hatta number confirmed that the water ozonization process develop in the liquid bulk, corresponding to very slow kinetic regime, then bubble column is advisable to obtain a high water quality in all practical cases considered. Water treatment systems are in service in several plants at different operating conditions. Source: 2nd International Symposium on Ozone Applications Havana, Cuba - Mach 24-26, 1997.
