Fresh water method |
| abstract |
(57) [Problem] To provide a composite membrane having a high pressure resistance and a small change in separation characteristics of a membrane even when a pressure of 70 atm or more is applied, and a small change over time in performance when operated at a pressure of 70 atm or more. The method of fresh water used is provided. A composite membrane having a separation function layer provided on a support membrane having a two-layer structure of one layer having pores and the other layer having a pore diameter larger than that of this layer is provided. To treat water at an operating pressure of 50 atm or more. |
