There are two main reasons that the micro-bubble has recently attracted wide attention. It can highly be adsorbed on the contamination in waste water in enclosed areas such as dams, lakes, and marshes. A large quantity of micro-bubble introduced into a body of polluted water will be adsorbed on the contaminations and bring them to the surface of the water. Also, the micro-bubbles oxygenate the water, which results in improved conditions for fisheries breeding and crop cultivation. In this study we measured the size and number of bubbles generated by two bubble generators under a variety of water and air flow rates. The most consistent bubble diameter produced by one generator was 20-50 μm, with approximately 2000 bubbles per 10 ml of water. Our goal is to develop a bubble generator that will produce a high number of fine bubbles with the least amount of power.
