Abstract This study was performed to investigate the effect on element such as swirling chamber and breaker disk in pressurized-dissolution type micro-bubble generator. And, to show the effect of element measured bubble size distribution, Sauter mean diameter and volumetric mass transfer coefficient as performance indicators of pressurized-dissolution type micro-bubble generator. And the results of experiments was summarized quantitatively. As a results of several experiments, breaker disk was shown up the best efficiency than other cases in aspect of effect on bubble size, which contribution ratio for D50 and Sauter mean diameter are 27.84%, 45.16% respectively. Also, in aspect of effect on volumetric mass transfer coefficient, swirling chamber B was shown up the best efficiency than other cases. The contribution ratio for volumetric mass transfer coefficient was 345.59%. Hence, the composition of additional equipment for improving efficiency of pressurized dissolution type micro-bubble generator was recommended using breaker disk and swirling chamber B type.
