DEEP SEAWATER, METHODS OF INTAKING AND USING DEEP SEAWATER AND METHOD OF PRODUCING DEEP SEAWATER PRODUCT

Document Type and Number:

WIPO Patent Application WO/2007/058314

Kind Code:

A1

Abstract:

Deep seawater is defined as seawater deeper than 200 m below the surface (the compensation depth) where sun’s rays cannot reach. Because of having favorable characteristics such as high stability at low temperatures, high cleanness, eutrophic properties, maturity and high mineral content, studies have been made to intake and utilize deep seawater. To effectively utilize deep seawater, however, it is necessary to select, intake and use deep seawater suitable for the purpose of using while considering economic efficiency. Thus, the existing techniques including patents and technical terms should be revised based on new findings and studies and discussions should be made on the novel definition of deep seawater and novel effects and utilization methods of deep seawater. Depending on the vertical distributions of various factors, the location of deep seawater being excellent in cleanness and maturity is specified. At the same time, a method of producing drinking water by efficiently taking advantages of deep seawater, important points to be noticed in fishery, techniques for using deep seawater in food processing, methods of using deep seawater for medical and health purposes, etc. are indicated.
