    • The purpose of the present invention is to provide a device for measuring osmosis pressure and a method for measuring osmosis pressure using the same. Provided in the present invention are the device for measuring osmosis pressure and the method for measuring osmosis pressure using the same, which comprise: a pressure-retarded osmosis cell including a draw solution unit which includes an inlet for receiving a draw solution and an outlet for discharging the draw solution, an influent water unit which includes an inlet for receiving an influent water and an outlet for discharging the influent water, and a pressure-retarded osmosis film which is included on the boundary between the draw solution unit and the influent water unit; a draw solution supply unit which is connected with the inlet of the draw solution unit; an air compression ratio measuring pipe which is connected with the outlet of the draw solution unit; a pressure sensor which is connected with the air compression ratio measuring pipe in order to measure the pressure generated by pressure-retarded osmosis; and an influent water which is connected with the inlet of the influent water unit in order to supply the influent water. According to the present invention, the air compression ratio measuring pipe is installed in a semi-continuous process which can generate osmosis pressure using a small amount of the draw solution, in order to measure osmosis pressure generated by the compression ratio of a compressed air layer due to pressure-retarded osmosis. Furthermore, the device prepared by the present invention can be used by applying to performance evaluation of the pressure-retarded osmosis film and replacement cycle measurement of the pressure-retarded osmosis film.

    • The present invention relates to a forward osmosis membrane and a method of manufacturing thereof, and more particularly, to a forward osmosis membrane in which a single support layer, which is a structure layer of the forward osmosis membrane, is treated with hydrophilic polymer to improve internal concentration polarization (ICP) of the forward osmosis membrane; and to a method of manufacturing thereof. The forward osmosis membrane according to the present invention has superior mechanical strength and the single support layer is coated with hydrophilic polymer to provide a hydrophilic layer, thereby improving the ICP generated in a complex film, which is well-known as the conventional forward osmosis membrane, and having excellent water permeability. Therefore, the forward osmosis membrane may be used effectively in a water treatment process for treating seawater, salt water, sewage, and waste water, particularly, in a desalination process.
