PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module capable of completely removing suspended matters adhered to a hollow fiber membrane.SOLUTION: Raw water flows in an inflow port 1e, an inflow chamber 5, holes 4a, a treatment chamber 6, communication pipes 10, a discharge chamber 9, and an outlet 1f. Permeable water which has permeated hollow fiber membranes 2 is taken out from a permeable water chamber 7 via a take-out port 1g. When bubbling cleaning is performed, air is supplied from the inflow port 1e. The holes 4a and the communication pipes 10 are provided equally in whole area of potting parts 4, 3, therefore all upper parts of hollow fiber membranes 2, are sufficiently cleaned by bubbling cleaning. |
