It is expected that fine bubbles increase the rate of gas dissolution into a liquid phase. To disperse the submilli-bubbles whose diameter is less than 1 mm, a novel gas distributor was developed. By scaling up a single slit orifice that generates submilli-bubbles, previously proposed by the authors, a multislit submilli-bubble distributor was developed for practical use. The distributor generated smaller bubbles, and realized higher gas holdup and higher volumetric mass transfer coefficient than the conventional distributors did. The bubbles distributed from each slit were hardly affected by the number of slits. The gas holdup in the case of submilli-bubble aeration was higher than those in the case of conventional gas distributors. The multislit submilli-bubble distributor showed fast gas dissolution rate.
