Introduction to the principle of reverse osmosis membrane

The reverse osmosis membrane is the core element to realize reverse osmosis, and it is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. Generally made of polymer materials. The chemical structure of some polymer materials has more hydrophilic groups, so the permeation speed of water is relatively fast. Therefore, a satisfactory reverse osmosis membrane should have an appropriate amount of permeation or salt rejection.
