  • Composite separation membrane and separation membrane element using the same
    Patent number: 10350553
    Abstract: The present invention provides a composite separation membrane with improved separation performance, particularly with an increased permeation flux. The composite separation membrane of the present invention includes a porous support (2) and a separation functional layer (1) formed on this support (2). The separation functional layer (1) is a polyamide membrane having a “double-folded structure” including a first layer portion (11) with a plurality of projections (15a, (15b . . . ) and a second layer portion (12) that covers at least one or some (15c and 15d) of these projections. Some projections (15a and 15b) of the first layer portion (11) extend upward and branch to form the second layer portion (12). There is a vacant space (13) between the first layer portion (11) and the second layer portion (12).
