The present invention relates to a method for producing a hollow fiber membrane-embedded membrane module, and more particularly to a method for producing a hollow fiber membrane-embedded membrane module which is used for a desalination or water purification device, and which has an improved membrane module structure. The present invention relates to a method for producing a hollow fiber membrane-embedded membrane module for use in a desalination or water purification device, and more particularly to a method for producing a hollow fiber membrane-embedded membrane module which is used for a desalination or water purification device, and which has an improved membrane module structure. In general, a membrane module used in a desalination or water purification device is composed of a plurality of membrane elements, and each of the membrane elements is composed of a plurality of membrane units. Each of the membrane units is formed of a hollow fiber membrane and a supporting tube. The hollow fiber membrane is disposed in a tubular shape, and the supporting tube is disposed outside the hollow fiber membrane. In order to provide a high concentration of purified water, a high membrane packing density is required. Accordingly, the present invention provides a method for producing a hollow fiber membrane-embedded membrane module which is used for a desalination or water purification device, and which has an improved membrane module structure. In accordance with an aspect of the present invention, there is provided a method for producing a hollow fiber membrane-embedded membrane module, comprising the steps of: forming a membrane unit by disposing a hollow fiber membrane in a tubular shape and disposing a supporting tube outside the hollow fiber membrane; providing a first membrane layer by placing the membrane unit in a first direction; placing the membrane unit in a second direction different from the first direction on the first membrane layer; forming a second membrane layer by placing the membrane unit in the second direction on the first membrane layer; and forming a membrane module by stacking the first and second membrane layers. The membrane unit may be formed by disposing a hollow fiber membrane in a tubular shape and disposing a supporting tube outside the hollow fiber membrane. The hollow fiber membrane is formed by extruding a polymeric material through an extrusion die. The formation of the first and second membrane layers may be performed by placing the membrane unit in a first direction and placing the membrane unit in a second direction different from the first direction on the first membrane layer. The first and second membrane layers may be formed in a staggered arrangement. The membrane module may be formed by stacking the first and second membrane layers. The stacking of the first and second membrane layers may be performed in a direction perpendicular to the first and second directions.

FIG. 1 is a perspective view illustrating a membrane module produced in accordance with an embodiment of the present invention. Referring to FIG. 1, the membrane module 10 includes a plurality of membrane units 100. Each of the membrane units 100 includes a hollow fiber membrane 110 and a supporting tube 120. The hollow fiber membrane 110 is disposed in a tubular shape, and the supporting tube 120 is disposed outside the hollow fiber membrane 110. The membrane module 10 includes a first membrane layer 130 and a second membrane layer 140. The first membrane layer 130 is formed by placing the membrane unit 100 in a first direction. The second membrane layer 140 is formed by placing the membrane unit 100 in a second direction different from the first direction on the first membrane layer 130. The first and second membrane layers 130 and 140 are formed in a staggered arrangement. That is, the first and second membrane layers 130 and 140 are arranged such that the membrane units 100 of the first membrane layer 130 and the membrane units 100 of the second membrane layer 140 are not aligned in the same direction. The membrane module 10 is formed by stacking the first and second membrane layers 130 and 140. The stacking of the first and second membrane layers 130 and 140 is performed in a direction perpendicular to the first and second directions.

Referring to FIG. 2, in step S200, a membrane unit is formed. The membrane unit is formed by disposing a hollow fiber membrane in a tubular shape and disposing a supporting tube outside the hollow fiber membrane. The hollow fiber membrane is formed by extruding a polymeric material through an extrusion die. The supporting tube is formed by extruding a polymeric material through an extrusion die. In step S210, a first membrane layer is provided. The first membrane layer is formed by placing the membrane unit in a first direction. In step S220, the membrane unit is placed in a second direction different from the first direction on the first membrane layer. In step S230, a second membrane layer is formed. The second membrane layer is formed by placing the membrane unit in the second direction on the first membrane layer. In step S240, a membrane module is formed. The membrane module is formed by stacking the first and second membrane layers. The stacking of the first and second membrane layers is performed in a direction perpendicular to the first and second directions. As described above, the present invention provides a method for producing a hollow fiber membrane-embedded membrane module. The membrane module produced by the method of the present invention has an improved membrane module structure. In particular, the membrane module has a high membrane packing density and thus provides a high concentration of purified water.
