Reverse osmosis membrane is the core component for achieving reverse osmosis, which is an artificial semi permeable membrane with certain characteristics made from simulated biological semi permeable membranes. It is usually made of polymer materials. For example, cellulose acetate film, aromatic polyhydrazine film, and aromatic polyamide film. The diameter of surface micropores is generally between 0.5-10nm, and permeability is related to the chemical structure of the membrane itself. Some polymer materials have good salt resistance, but poor water permeability. Some polymer materials have more hydrophilic groups in their chemical structure, so the permeation rate of water is relatively fast.

The product sizes include:

4-inch reverse osmosis membrane, 8-inch reverse osmosis membrane, 4040 reverse osmosis membrane, 8040 reverse osmosis membrane
