The present invention provides a hollow fiber membrane module that can effectively resolve the accumulation of suspended solids within the membrane module, lower running costs, and also operate stably. The present invention relates to a hollow fiber membrane molecule provided with: a cylindrical case having a first end and a second end in the direction of height; a plurality of hollow fiber membranes accommodated within the cylindrical case; and a first potting part accommodated within the cylindrical case and attaching the plurality of hollow fiber membranes together such that the end parts of the plurality of hollow membrane fibers at a first end side of the cylindrical case are open. The hollow fiber membranes are porous hollow fiber membranes having a breaking strength of 23 MPa, and the hollow membrane module has a membrane area per unit volume of 800-3700 m/m. The filling fraction for the hollow fiber membranes in a cross-section orthogonal to the direction of height of the cylindrical case is 25-38%.

Hollow fiber membrane module and method for operating same

In order to efficiently transport a filtration target liquid to a separation membrane module and to facilitate additional simplification of equipment in a filtration device including the separation membrane modules in which a plurality of lines thereof are disposed in series, a filtration device according to the present invention is a filtration device including a plurality of separation membrane modules each of which separates a liquid to be filtrated into a permeated liquid and a non-permeated liquid, in which the filtration device includes: a series non-permeated liquid flow channel that forms a series unit by connecting non-permeation sides of the plurality of separation membrane modules in series; and a parallel permeated liquid flow channel that forms a parallel unit by connecting permeation sides of the plurality of separation membrane modules in parallel.
