What is a Reverse Osmosis Membrane？
Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable 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, these substances and water are separated according to the fact that other substances cannot pass through the semi-permeable membrane. The pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.
What are the characteristics of reverse osmosis membrane?
(1) high-efficiency desalination rate at high flow rate;
(2) high mechanical strength and service life;
(3) Can function under lower operating pressure;
(4) Resistant to chemical or biochemical effects;
(5) Less affected by factors such as pH value and temperature;
(6) The source of film-making raw materials is easy, the processing is simple, and the cost is low.
What are the main materials of reverse osmosis membrane?
The currently used membrane materials are mainly cellulose acetate and aromatic polyamides. Its components are hollow fiber, coil, plate and frame and tubular
What is the filtration accuracy of reverse osmosis membrane?
The reverse osmosis membrane can intercept substances larger than 0.0001 micron, and is the most delicate membrane separation product. It can effectively intercept all dissolved salts and organic substances with a molecular weight greater than 100, while allowing water molecules to pass through.
What need to be considered when choosing a RO membrane?
Desalination rate, water production and recovery rate.
