DESALINATION SYSTEM AND DESALINATION METHOD |
摘要 |
This desalinization system, which obtains industrial-use water and drinking water from seawater and wastewater, is provided with: a purification device that purifies wastewater by removing activated sludge therefrom; a first RO membrane that removes salt from the output of the purification device by transferring said salt to first concentrated water, thereby producing industrial-use water; a UF membrane that seawater passes through and that removes particulates from said seawater; a second RO membrane that removes salt from the treated output of the UF membrane by transferring said salt to second concentrated water, producing drinking water; an agitation device to which the second concentrated water from the second RO membrane and the first concentrated water from the first RO membrane are sent to be agitated; and a third RO membrane removing salt from the liquid mixture agitated by the agitation device by transferring said salt to third concentrated water, producing industrial-use water. |

1. A sea-water desalination system for acquiring industrial water and drinking water from sea-water and sewage water, comprising: a purification apparatus for removing activated sludge by permeating the sewage water; and purifying; a UF membrane for removing particles in the sea-water by permeating the sea-water; a first RO membrane for permeating treated water which permeated the UF membrane; and including and removing salinity of the treated water in first concentrated-water and also generating drinking water; a stirring apparatus for stirring the first concentrated-water removed by the first RO membrane and treated water which permeated the purification apparatus being sent thereto; and a second RO membrane for permeating mixture fluid stirred by the stirring apparatus; and including and removing salinity thereof in second concentrated-water and also generating industrial water. |
