Eutrophication in the closed water body, such as lakes and dam reservoir, is attracting more and more attention. The huge amount of phytoplankton growth caused this eutrophication. To prevent eutrophication, nowadays, much effort should be used in our society. To control of water pollution in the large-scale dam reservoirs, the water circulation system by big-size aerator was introduced. However, the effective results were not obtained for the spent of huge energies and costs. Under the industry-university/college cooperation, the energy-saving type oxygen supply device is able to be applied to the closed water body was developed. It is possible to carry out both the oxygen supply into the water and the water transport simultaneously by using this new device. The experiments were conducted in both the swimming pool of the college and the Tokiwa Lake in Ube City, Japan.
