MODELING HYDRODYNAMICS AND MASS-TRANSFER PARAMETERS IN A CONTINUOUS OZONE BUBBLE-COLUMN

A computer model based on the establishment of mass balance equations and on the model of fluids flow ''stirred tank in series'' was develop ed in order to calculate the ozone transfer coefficient k(L)a and kine tic constant k(c) of ozone consumption by water. On the basis of exper imental data, the correlation for gas holdup epsilon(g) and bubble dia meter d(vg), were proposed and used to calculate the specific interfac ial area a. The liquid-phase mass transfer coefficient k(?)L for ozone was evaluated from a and the k(L)a data.
