The grooves of the third and fourth membrane distillation module basic structures 200c and 200d are formed by the first fluid F1 having the first partial pressure and the second fluid F2 having the second partial pressure, And the second separation membrane S2 may be disposed between the third and fourth membrane distillation module basic structures 200c and 200d. The grooves of the fifth and sixth membrane distillation module basic structures 200e and 200f are formed by the first fluid F1 having the first partial pressure and the second fluid F2 having the second partial pressure, And the third separation membrane S3 may be disposed between the fifth and sixth membrane distillation module basic structures 200e and 200f. Thereby, it is possible to provide the first and second membrane distillation module basic structures 200a and 200b, between the first and second membrane distillation module basic structures 200a and 200b, between the second and third membrane distillation module basic structures 200c and 200d, Water vapor may be transferred between the first and second fluids F1 and F2 between the structures 200e and 200f and the desalination process may proceed.

Also, as described above, the multi-stage membrane distillation module in which the first fluid (F1) and the second fluid (F2) are moved to the other membrane distillation module basic structure through the external tube to facilitate maintenance and scale up Can be provided.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention.
