Micro-bubbles are used in the fields of aqueous environment, food, health care and marine areas. These conventional methods do not control the position of the micro-bubbles.This paper aims to actively control the behavior of micro-bubbles. The method of controlling the behavior of micro-bubbles is to give electrical field.The surfactants were added to the micro-bubbles. The electrical charge was given on surface of the micro-bubbles. Three kinds of surfactants were used. These are anionic, cationic and non-ionic surfactant. Result showed the velocity of micro-bubbles depended on the surfactants in the electric field condition.The anionic moved micro-bubbles in the positive electrode direction. The cationic moved micro-bubbles in the negative electrode direction.The non-ionic did not have an effect on the micro-bubbles.
