Zusammenfassung:Recently air bubble plume has been suggested as a method of water quality purification. In this study, air bubble characteristics, flow induced by air bubble rise and destratification by the flow have been investigated by field test. As the results of the study, following concequences were obtained. 1. Bubble diameter is 5-7cm. 2. Bubble velocity is 50-150cm/s and can be expressed by way of function of air supply. 3. Volume flux ratio can be explained by the equation which is induced in field in which there is not stratification. But there is the maximum value of volume flux ratio.
