Title: FLAT-SHEET SEPARATION MEMBRANE ELEMENT, ELEMENT UNIT, FLAT-SHEET SEPARATION MEMBRANE MODULE, AND OPERATION METHOD FOR FLAT-SHEET SEPARATION MEMBRANE MODULE
Abstract:
The present invention relates to a flat-sheet separation membrane element having formed therein a separation membrane pair in which separation membranes are disposed such that permeation-side faces thereof face each other and in which a channel material is provided, wherein the area of a high-elasticity region satisfying a bending modulus of 100-1000 MPa and a maximum bending stress of 1-15 MPa at least in one direction is not less than 10% of the area of a filtration region of the pair of separation membranes.
