Composite semipermeable membrane |
| abstract |
An object of the present invention is to provide a composite semipermeable membrane that achieves both high removability of substances other than water and high water permeability. The present invention is a composite semipermeable membrane comprising a porous support membrane and a separation functional layer, wherein the 10-point average surface roughness in the separation functional layer in a cross section having a length of 2.0 μm in the membrane surface direction. The average number density of protrusions having a height of 1/5 or more of the above is 10.0 / μm or more and 30.0 / μm or less, and the average height of the protrusions is less than 100 nm. The present invention relates to a composite semipermeable membrane in which the amount of water produced and the desalination rate after permeation are not less than a predetermined value. |
