Abstract
Micro-bubbles are very small air bubbles with diameters of the order of less than several tens microns and have become to attract people's concerns rapidly in the past several years due to their wide potential in practical applications to a variety of advanced technologies. Their generating technologies are also splendidly developed. However, complex device and high power supply are required for conventional micro-bubble generators. In this study, the compact and low power micro-bubble generator has been developed. In order to verify the applicability of purification system, experiments were conducted by changing the pH levels (pH:5 (acid), pH:7 (neutral), pH:9 (alkaline)) in the initial condition. The pH level approaches to neutral value after the micro-bubble generation for all cases.
