In recent years, with the public's higher and higher requirements for water quality, a variety of water purification products have also flocked to the market, all kinds of appearance, multiple functions, different fluxes and differences in filtration technology will appear difficult to choose; What is the difference between the popular RO and the emerging nanofiltration?
RO membrane reverse osmosis water purification technology
As a hot RO membrane reverse osmosis water purifier in the market, it has been favored by many consumers, and reverse osmosis technology was first used in the space capsule to solve the water problem of astronauts at the beginning of its invention. It is not difficult to imagine that in a small confined space like a space capsule, every drop of water is very precious, and astronauts' sweat, urine and bathing water need to be recycled, so reverse osmosis purified water is also called space water. At the same time, reverse osmosis technology is also being applied to seawater desalination and sewage treatment.
How it works
Permeation technology is a mature membrane liquid separation technology, in the inlet water (concentrated solution) side through the booster pump to apply the operating pressure to overcome the natural osmotic pressure, when the operating pressure higher than the natural osmotic pressure is added to the concentrated solution side, the flow direction of natural osmosis of water molecules will be reversed, the water molecules in the inlet water (concentrated solution) through the reverse osmosis membrane to become the dilute solution side of the purified produced water.
RO reverse osmosis membranes have a filtration accuracy of up to 00001-0.001 microns, can filter almost all dissolved impurities, including large and small impurities, so that the water quality is pure water.
Shangchengjian water hollow fiber nanofiltration membrane technology
Shangcheng Jianshui water purification equipment all uses hollow fiber nanofiltration membrane as the core component. Hollow fiber nanofiltration membrane is a key project of the national "863 Plan", which was designated as the official water treatment technology equipment during the 12th National Games, and was included in the national new material budget investment alternative project.
The hollow fiber nanofiltration membrane has excellent properties such as biological corrosion resistance, acid and alkali corrosion resistance, chlorine resistance, pressure resistance, etc., and its service life has reached the synchronization with the equipment, which greatly reduces the cost of use.
How it works
The hollow fiber nanofiltration membrane has the function of cell membrane biotransport and selective permeability and adsorption, which can remove toxic and harmful substances such as heavy metals, viruses, bacteria, and microorganisms in the water, retain the beneficial minerals in the water, and make the water quality weakly alkaline, and the vibration frequency of water molecules is between 80-85 Hz, which meets the national (CJ94-2005) direct drinking water standard. February** Dynamic Incentive Program
Compared with the pure water filtered by RO, the hollow fiber nanofiltration membrane can retain the beneficial minerals in the water, making the water quality weakly alkaline and more characteristic of healthy water. It is more worthy of choice for consumers who pursue a healthy quality of life.
At the same time, the RO filtration technology needs the support of an additional booster pump, while the Shangchengjian water hollow fiber nanofiltration membrane does not need to be plugged in, which is more in line with the concept of environmental protection in China.
Picky only for better choices, break the difficulty of choice, this time only for healthier water.
