RO is the abbreviation of English Reverse Osmosis, Chinese meaning reverse osmosis. The flow of water in general is from low concentration to high concentration, and once the water is pressurized, it will flow from high concentration to low concentration, which is the so-called reverse osmosis principle: Because the pore size of the RO membrane is one millionth of the hair (0.0001 micron), generally can not be seen by the naked eye, bacteria, viruses are 5000 times of it, therefore, only water molecules and some mineral ions can pass (through the ion is not beneficial to damage orientation), other impurities and heavy metals are discharged by the wastewater pipe. All seawater desalination processes, as well as the recycling and treatment of astronaut wastewater are used in this method, so RO membrane is also known as the high-tech “artificial kidney” in vitro. At home and abroad, in the medical military and civilian fields, the top RO membrane is used for polymer filtration.
Reverse osmosis is a new membrane separation technology developed in the 1960s, which relies on the reverse osmosis membrane to separate the solvent and solute in the solution under pressure. The full English name of REVERSE OSMOSIS is “Reverse osmosis”, abbreviated as “RO”.
RO (Reverse Osmosis) reverse osmosis technology is the use of osmotic pressure difference as the power of membrane separation and filtration technology, from the United States in the 1960s aerospace science and technology research, after gradually transformed into civil, has been widely used in scientific research, medicine, food, beverage, seawater desalination and other fields.
