US 2014/0151283 A1 · DESALINATION SYSTEM AND DESALINATION METHOD

Abstract

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.

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 first RO membrane for
permeating permeable water which permeated the purification apparatus;
and
including and removing salinity thereof in first concentrated-water and also generating industrial water;
a UF membrane for removing particles in the sea-water by permeating the sea-water;
a second RO membrane for
permeating treated water which permeated the UF membrane;
and
including and removing salinity of the treated water in second concentrated-water and also generating drinking water;
a stirring apparatus for stirring the second concentrated-water removed by the second RO membrane and the first concentrated-water removed by the first RO membrane being sent thereto;
and
a third RO membrane for
permeating mixture fluid stirred by the stirring apparatus;
and
including and removing salinity thereof in third concentrated-water and also generating industrial water.
