Abstract
To provide a method for manufacturing a module having a selectively permeable membrane wherein the surface of the selectively permeable membrane thereof can be washed with good efficiency and further contaminants having been exfoliated from the surface of the membrane by a washing operation can be discharged from the inside of a housing with good efficiency; and the above module having a selectively permeable membrane. A module wherein a selectively permeable membrane is held in a housing and both ends of the above selectively permeable membrane are fixed, the both ends of the above selectively permeable membrane are fixed to an upper holder and an under holder connected by at least one washing tube, and then, the membrane is held in the housing; and a module having a selectively permeable membrane manufactured by the above manufacturing method.
