Miniaturization Effect of Ozone/Oxygen Bubbles in Wastewater Purification Technology

Abstract

Ozone/oxygen mixed gas with different bubble diameters is supplied to ion-exchanged water or fulvic acid aqueous solution, and the effects of bubble diameter on initial ozone dissolution and reaction rates are quantified. As a result, it was clarified that both rates of the initial dissolution and reaction of ozone represent －0.5 order relative to the bubble diameter.
