Microbubbles are very small bubbles with diameters of 50μm or less. The important characteristics of microbubbles are their large specific area and small buoyancy and therefore effective dissolution of gas phase and adsorption rate are expected. The utilization of microbubble is useful to improve water environment. Research efforts at a number of institutions have been devoted to development of microbubble generator. However, complex mechanism and high power supply are required for previous microbubble generation devices. In this study, three types of model (slit angle θ=30, 60, 90 deg) were installed in order to develop the compact and low power microbubble generator and microbubbles were generated by pipe with slits. For θ=60 deg, the microbubble generator showed the superior performance in comparison with the other models. It was confirmed that the microbubble generation was affected by the slit angle.
