<p>PROBLEM TO BE SOLVED: To provide a membrane separation device and a membrane separation method, in each of which stains stuck to the vicinity of the permeation-side surface of a membrane can be discharged effectively.SOLUTION: The membrane separation device is constituted so that a supply-side flow passage material 2, a sheet-like separation membrane 1 and a permeation-side flow passage material 3 are piled in this order, and a supply-side flow passage and a permeation-side flow passage, which are formed on the inside of a main body 10, are divided from each other by the sheet-like separation membrane 1. The supply-side flow passage has an inlet 14 and an outlet 15 of an original liquid and the permeation-side flow passage has another inlet 16 and another outlet 17 of a sweep flow. At least one of the inlet 16 and the outlet 17 is selected and a plurality of the selected ones are formed at different positions.</p> |
