Abstract:
1. A hollow fiber membrane module unit comprising: a plurality of hollow fiber membrane modules each comprising: a plurality of sheet-form hollow fiber membranes, an anchoring member in which at least at least an end of a side of a hollow hollow fiber membrane that opens is fastened so that the plurality of sheet-form hollow fiber membranes are substantially parallel to each other while leaving the end of the hollow fiber membrane open, the anchoring member having an end face that is substantially rectangular on a side where the hollow fiber membranes are exposed, and the anchoring member having an end face that is substantially circular on the side where the hollow fiber membranes open, wherein the anchoring member has a substantially rectangular parallelepiped shape on a side where the hollow fiber membranes are exposed, and has a cylindrical section having a substantially cylindrical shape on a side where the hollow fiber membranes open, the hollow fiber membrane module satisfies the relationship 1.0≦W/D≦2.0, wherein W(mm) is a length of the longer side of the end face where the hollow fiber membrane is exposed to the rectangular parallelepiped section and D(mm) is a diameter of the cylindrical section, and a plate member having a hole through which the cylindrical section passes is provided on a side surface of the hollow fiber membrane perpendicular to the sheet surfaces of sheet-form hollow fiber membranes, and the hollow fiber membrane module is fastened by the plate member.
