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.

主权项

1. A sea-water desalination method for acquiring industrial water and drinking water from sea-water and sewage water, producing industrial water by making the sewage water permeate purification apparatus and first RO membrane; producing drinking water by making the sea-water permeate UF membrane and second RO membrane; and producing industrial water by making mixture fluid which mixed first concentrated-water removed by the first RO membrane and the second concentrated-water removed by the second RO membrane permeate third RO membrane.
