Background

The reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics and is made by simulating a biological semipermeable membrane, and is a core component of a reverse osmosis technology. The principle of reverse osmosis is that under the action of a pressure higher than the osmotic pressure of a solution, other substances are separated from water by means of a semipermeable membrane which is impermeable to these substances. The reverse osmosis membrane has a very small membrane pore size, and thus can effectively remove dissolved salts, colloids, microorganisms, organic substances, and the like in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, simple and convenient operation and the like.

The reverse osmosis membrane is divided into a low pressure reverse osmosis membrane and a low pressure reverse osmosis membrane, and the difference between the two is that the filtration pore diameter of the high pressure anti-osmosis membrane is about 0.0001 micron, the filtration pore diameter of the low pressure reverse osmosis membrane is about 0.0005 micron, and raw water of the low pressure reverse osmosis membrane passes through the reverse osmosis membrane slowly by itself and is stored in a pure water barrel.
