Composite semipermeable membrane, and production process thereof |
| 摘要 |
A composite semipermeable membrane which satisfies the following relationship when seawater at 25° C. having a pH of 6.5, a boron concentration of 5 ppm and a TDS concentration of 3.5% by weight is permeated under an operation pressure of 5.5 MPa: Boron removal ratio (%)>=95-4xmembrane permeation flow rate (m<SUP>3</SUP>/m<SUP>2</SUP>.day).
