Among them, the reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. It is the core component of reverse osmosis technology. The reverse osmosis membrane can separate these substances and water under the action of higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water. It has the advantages of good water quality, low energy consumption, no pollution, simple process, and easy operation.

[0018] The beneficial effects of the utility model are:

[0019] (1) The pressure-bearing support plate prepared by the utility model adopts a bowl-shaped structure, which makes the structure of the pressure-bearing support plate stable and rigid, and has strong pressure-bearing sealing performance.
