Abstract
Recently, water quality in receiving water has been polluted, and this problems effect on the aquatic products, sight-seeings and leisure industries.
From now on, ocean age has come. The international law of the sea with 200 sea miles was decided. It is important for japan to make clear how to preserve and to develop the sea. Therefore, we have developed the purification method which use the energy of the waves and the ebb and flow. And we think that this new purification method may help the preservation of the water quality and development of the sea and lakes.
“The purification system for the sea water area” can improve the water quality. For example, they are red tide, pollted river water, domestic sewage, oil pollution, storm surge, tidal wave, drift sand and splash of sea water. And this system demonstrates marine productivity eternally.
