Composite semipermeable membrane, separation membrane element, and process for producing said membrane |
| abstract |
Provided are a composite semipermeable membrane that will maintain a sufficient level of rejection performance even when produced using different thicknesses of a porous support or different production conditions, a separation membrane element having such a composite semipermeable membrane, and a method for producing such a composite semipermeable membrane. The composite semipermeable membrane includes a porous support including a nonwoven fabric layer and a polymer porous layer on one surface of the nonwoven fabric layer; and a separation function layer on the surface of the porous support, wherein the porous support has a defect frequency F1 of 50 or less per 480 m 2 with respect to defects having a width of 0.3 mm or more perpendicular to the direction of the polymer porous layer production line, when the relationship between the size and frequency of defects in the porous support is measured with transmitted light. |
