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.
