Production and application of RO reverse osmosis membrane
- RO membrane and Seagulls
The seagull body, there is a film, the film is very precise, seawater through the seagull inhalation body, pressure, and then through the pressure, the water molecules through, permeate the film, into fresh water. Seawater containing impurities and high concentration of salt is spewed out of the mouth.
This film in the gulls throat is the prototype of the reverse osmosis film.
RO reverse osmosis technology, is the United States in the 1960s, developed a kind of ultra-precise use of pressure difference membrane separation technology. It is a membrane separation permeation technology that works by pressurizing, and the water penetrates from high concentration to low concentration after pressurizing, and takes the osmotic pressure difference as the driving force.
Water molecules permeate the RO membrane, removing heavy metals, organic matter, inorganic matter, bacteria and viruses from the water.
RO membrane filtration is very high, its hole distance is only 0.0001 micron, so it can achieve the purpose of purifying water quality.
- The significance of reverse osmosis membrane
The filtration effect depends on the filtration accuracy of the filter element, the filtration accuracy from strong to weak, in order: RO reverse osmosis > nanofiltration > ultrafiltration > microfiltration RO reverse osmosis water purifier, is the safest drinking water solution. This kind of filtered water is direct drinking water, which is a qualitative leap for the purification of water.
RO reverse osmosis water purifier is the safest drinking water solution. This kind of filtered water is direct drinking water, which is a qualitative leap for the purification of water.
The reverse osmosis membrane has a filtration accuracy of 0.0001 micron, which is one millionth of a human hair.it can filter all impurities in the water, only allow water molecules to pass.
RO reverse osmosis membrane, generally 2 to 3 years to replace once. As long as the RO reverse osmosis membrane can be used, the other membranes thrown away do not affect the filtration effect, the replacement frequency does not need to consider other filter elements, and it will be replaced together at the time.
