With the improvement of residents’ living standards and health awareness, the current residents are paying more and more attention to water pollution. Therefore, even in today’s downturn in the home appliance industry, the scale of the water purifier market is still growing steadily. In 2020, the sales volume of water purifiers in my country will exceed 10 million units, of which reverse osmosis water purifiers account for more than 75%, far ahead of other water purifiers. Technical water purifier.
Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses a pressure difference as a driving force to separate a solvent from a solution. Apply pressure to the feed liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reverse osmosis against the direction of natural osmosis. The reverse osmosis water purifier adopts the filtration technology of this principle.
The core of the reverse osmosis water purifier is the RO membrane filter element. Its interception accuracy is as high as one ten thousandth of a micron (0.0001 micron), and only water molecules and a small amount of minerals and trace elements are retained. We know that 1 micron = 1000 nanometers, the diameter of bacteria is relatively large, generally more than 1 micron; the diameter of coronavirus is between 80 and 120 nanometers, and the pore size of RO reverse osmosis membrane is less than 1 nanometer, so filtering bacteria and viruses is not natural. Next. In addition, harmful substances such as heavy metal ions and antibiotics can also be easily intercepted by the RO reverse osmosis membrane of the reverse osmosis water purifier.
Because the interception resistance of the reverse osmosis membrane is very large, the reverse osmosis water purifier is generally equipped with a pressurized pump, which requires electricity and generates waste water. Of course, wastewater can be reused, and it is a good choice for washing clothes, mopping floors, and watering flowers.
Water is the source of life. People can live a week without food, but only three days without water. Whether at home or outside, we all need to drink more water, drink healthy water, clean water, safe water. Compared with other water purifiers, the reverse osmosis water purifier has more complete functions, integrating microfiltration, adsorption, reverse osmosis, ultra-purification and other technologies, making it fresher, more hygienic and safer. Under the current trend of “quality consumption, healthy life”, consumers pay more attention to safety and health, so they are more willing to buy reverse osmosis water purifiers.
