Reverse osmosis equipment and membrane technology
Reverse osmosis (RO) is a high-tech membrane separation technology driven by pressure difference, which has the characteristics of high primary separation, no phase change, simple and efficient. The "pore diameter" of reverse osmosis membrane is as small as nanometer. Under the operating pressure higher than the osmotic pressure of raw water, water molecules can reverse osmosis through ro semi permeable membrane to produce pure water, while a large number of inorganic ions, organics, colloids, microorganisms, soluble salts and organics with molecular weight greater than 100 in raw water, pyrogen, etc. are retained by RO membrane. However, when water molecules are allowed to penetrate, the desalination rate of RO composite membrane is generally greater than 98%.
