The objective of this study was to characterize the hydrodynamic 
behavior of a pilot scale bubble column. The mixing study proceeds 
with the experimental determination of the residence time 
distribution (RTD) by means of tracer test at a variety of gas and 
liquid flowrates. Liquid flow behavior was evaluated from 
different mathematical models using a computer software. The 
effect of some hydraulic parameters and bubble size on the extent 
of dispersion were evaluated. On the other hand, the profiles of 
dissolved ozone in water along the column were determined. This 
study makes possible the improvement ozone process efficiency, 
thereby to evaluate design and operating conditions alternative 
for the same type of existing contactors equipped with identical 
gas diffusion system.
