Abstract: Abstract:Based on the reverse osmosis sea water desalination pilot scale test, the operation pressure temperature characteristics and the desalination rate temperature characteristics of the sea water desalination system under condition of constant membrane flux were analyzed. Comparing the software simulation data and the site pilot scale test data, it was verified that under condition of constant membrane flux, when the temperature is increasing, the operation pressure decreases gradually, and the desalination rate decreases gradually too.
