| Research Abstract |
High functional characteristics of micro-bubbles and water purification effect using the techniques of the bubble are investigated. Two types of micro-bubble generator are useful to control the generation of plant plankton and cut off the plankton flowing for downstream in the surface layer of dam lake. Further, the bleeding conditions of oyster raised by injection of the micro-bubble are investigated in Hiroshima Bay. It was clear that micro-bubble supply at regular intervals help a remarkable growth of raising oyster. These effects associate with the high functional chemicophysical characteristics of micro-bubbles having diameter about 10 〜 30 μm.
And these results show to revive polluted water environment useful.
