Reverse osmosis membrane is the core component for achieving reverse osmosis, and is an artificial semi permeable membrane made by simulating biological semi permeable membranes with certain characteristics. Generally made of polymer materials. Such as cellulose acetate film, aromatic polyhydrazide film, and aromatic polyamide film. The diameter of surface micropores is generally between 0.5 and 10nm, and the size of permeability is related to the chemical structure of the membrane itself.
Characteristic(1) It should have an efficient desalination rate at high flow rates;
