Abstract: Disclosed is a vapor splitter including: a chimney tray dividing an internal space of a housing into an upper space and a lower space; a chimney provided on the chimney tray to enable the upper space and the lower space to communicate with each other; a cap covering the chimney with a gap therebetween such that a gas discharge hole is formed so that gas, coming out through the chimney, can be transferred to the upper space through the gas discharge hole; a liquid feeding unit for feeding liquid to the upper space; and a liquid discharging unit for discharging the liquid out of the upper space. The size of the gas discharge hole is adjusted by controlling the height of the liquid collected on the chimney. Further disclosed is a method of adjusting a vapor split ratio using the vapor splitter.

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.
