A polyether reverse osmosis composite membrane "PFT" was prepared. The supporting membrane was an asymmetric ultrafiltrate membrane made from polyetheretherketone "PEK-C". The active layer was a sulfonated closslinked polycondensate made by in-situ polymerization of furfuryl alcohol and tris-(2-hydroxyethyl)isocyanurate. The constitution of the casting solution of PEK-C and the additives to the composite membrane solution on the performance of PFT membrane have been discussed. The title membrane gave over 99.6% salt rejection and 0.30m³/m² per day Water flux at pressure of 4.9MPa with 1.5% NaCl aqueous solution.
