Abstract: PURPOSE: A method for manufacturing a polyvinyl alcohol(PVA)-zeolite composite membrane and a method for manufacturing the same are provided to concentrate organic materials by efficiently separating water from the mixture of the water and the organic materials. CONSTITUTION: A method for manufacturing a PVA-zeolite composite membrane includes the following: a PVA aqueous solution containing 5-20 weight% of PVA and 80-95 weight% of distilled water based on the total weight of the aqueous solution is prepared; 5-10 parts by weight of a cross-linking agent is added into 100 parts by weight of the PVA aqueous solution, and the mixture is stirred for 12 hours to 3 days at a temperature between 5 and 40 degrees Celsius; zeolite powder is added into the stirred solution and is stirred for 12 hours to 10 days at a temperature between 5 and 40 degrees Celsius to prepare a PVA-zeolite solution; and the PVA-zeolite solution is applied and dried for 20 to 50 hours at a temperature between 30 and 100 degrees Celsius to obtain a PVA-zeolite composite membrane.
