Do you Know RO Membrane?
May. 07, 2021
Reverse osmosis membrane is an artificial semi-permeable membrane with
certain characteristics made by simulating biological semi-permeable membrane,
and it is the core component of reverse osmosis technology. The principle of
reverse osmosis technology is that under the action of higher than the osmotic
pressure of the solution, other substances cannot pass through the
semi-permeable membrane and these substances and moisture are removed. The
membrane pore size of the reverse osmosis membrane is very small, so it can
effectively remove dissolved salts, colloids, microorganisms, and organic matter
in the water. The system has the advantages of good water quality, low energy
consumption, no pollution, simple process and easy operation.

Reverse osmosis membrane is the core element to realize reverse osmosis, and it is an artificial semi-permeable membrane with certain characteristics made by simulating biological semi-permeable membrane. Generally made of polymer materials. Such as cellulose acetate film, aromatic polyhydrazide film, aromatic polyamide film. The diameter of the surface micropores is generally between 0.5 and 10 nm, and the permeability is related to the chemical structure of the membrane itself. Some polymer materials have good repellency to salt, but the water penetration rate is not good. The chemical structure of some polymer materials has more hydrophilic groups, so the water permeation rate is relatively fast. Therefore, a satisfactory reverse osmosis membrane should have an appropriate amount of permeation or salt rejection rate.
The reverse osmosis membrane should have the following characteristics: (1) It should have an efficient salt rejection rate at high flow rates; (2) It has high mechanical strength and service life; (3) It can function under lower operating pressure; (4) It can Resistant to chemical or biochemical effects; (5) Less affected by factors such as pH value and temperature; (6) Easy source of raw materials for membrane making, simple processing and low cost.
