The aim of this study is to control micro-bubble diameter. The micro-bubble is generated by means of injecting gas through spinning porous plate. In the study, we report the influences on micro-bubbles by surface tension, surfactant concentration and circumferential velocity of the micro-bubble generation area. By increasing circumferential velocity, the diameter of bubbles decrease. Also as surface tension is lower by increasing surfactant concentration, the diameter of bubbles is decrease. However, under the condition of surface tension is constant, the diameter of micro-bubble doesn't decrease with overmuch surfactant addition. It is proved that the diameter of bubble depends on the surface tension and circumferential velocity.
