  • Forward osmosis performance improved membrane apparatus and method of separating solution using the same
    Patent number: 11090609
    Abstract: A membrane apparatus including a housing, a forward osmosis membrane dividing an internal space of the housing into an inlet region and a mixing region, and a pervaporation membrane dividing the internal space of the housing into the mixing region and a discharge region. The forward osmosis membrane separates a preliminary filtration liquid from an inlet liquid and provides the separated preliminary filtration liquid to the mixing region, the preliminary filtration liquid is mixed with a forward osmosis draw solution to make a mixed solution, the pervaporation membrane separates a final filtration liquid from the mixed solution and provides the separated final filtration liquid to the discharge region, the final filtration liquid is vaporized in the discharge region to make vapor, and an amount of the vapor is adjusted by at least one of a temperature of the mixed solution and a degree of vacuum of the discharge region.
