Abstract：

In order to solve the problem of desalination of high salinity brackish water in remote areas, this work carried out experimental research on nanofiltration desalination of high salinity brackish wateran experimental study on nanofiltration desalination of high salinity brackish water was conducted in this work. The effect of operating conditions on the performance of domestic commercial 4040 nanofiltration membrane VNF2 was simulated evaluated using a simulated salt solution, . and tThe desalination performance of VNF2 and that of an imported nanofiltration membrane (ESNA1) was were compared. The results demonstrate that the permeation flux and salt rejection of VNF2 increase with the increase of operating pressure, and decrease with the increase of the feed salt concentration; . Compared with ESNA1, VNF2 can effectively desalinate brackish water with a high salinity of 10 g/L to the level of fresh water, . and tThe salt content of its permeate produced water is less than 0.6 g/L, which can meet the standardsGuidelines for Drinking Water Quality of China (< 1 g/L); ). The operating pressure of the desalination process is lower than 1.6 MPa. This operating pressure range enables the desalination system to use engineering plastic pipes and valves, which can make the assembly and maintenance of the equipment simple and solving solve the equipment anti-corrosion problem of corrosion protection and welding of stainless steel materials, which has great practical significance.
