<P>PROBLEM TO BE SOLVED: To provide a water treatment method by which fresh water with high amount of dissolved oxygen and large amount of mineral components can be obtained from seawater. <P>SOLUTION: In a water treatment system equipped with an ozone generator, an ozone treatment device, a filtration device and a reverse osmosis membrane, the ozone treatment device equipped with a baffle plate at a predetermined position inside the device is used, seawater is made to flow into the ozone treatment device to form a turbulent flow so as to diffuse ozone to whole seawater and to perform ozone treatment. Thus oxygen nanobubbles around which mineral component ions are condensed are produced, then are made to pass through the filtration device and the reverse osmosis membrane to produce the fresh water and the obtained fresh water flows out of the water treatment system. <P>COPYRIGHT: (C)2007,JPO&INPIT |
