風力エネルギーによる水質浄化システムに関する実験的研究（第1報，低風速域における特性改善）

In recent years, pollution of the water in eutrophic lakes and marshes become an important problem. To improve this situation, we developed the water purification system by using the wind energy. In the present system, the Savonius wind turbine with the guide vane was used and the micro bubble was generated by this wind turbine to purify the quality of water. The most important characteristic of this system is to possess the wind energy conservation apparatus. That is, the wind was converted into the water pressure by using the accumulator to make the most use of the weak wind energy. To clarify the effectiveness of the present system, the field test was carried out. Test results showed that the micro-bubble was generated intermittently even in relatively low wind velocity condition, and the generation frequency of the micro-bubble was in proportion to the cube of the wind velocity.
