1, microfiltration technology is mainly microporous membranes as a medium, the filtration accuracy of 0.1 microns, can only be effective in removing silt in the water, clay, and other suspended solids, not able to filter out the macromolecules of organic matter with the Inorganic salts. Because of its low filtration precision, life is also short, also makes the cartridge needs to be replaced frequently, so it is not widely used.
2, ultrafiltration technology is pressure-driven, ultrafiltration membrane to filter out pollutants, filtration precision of 0.01 microns, so it can filter out most pollutants, including colloids, suspended solids, macromolecules and organics, and will retain the same minerals. In view of its long service life, filtered water can be directly drinkable, most manufacturers in the market will be combined with other filter materials, in the kitchen water and other aspects play an important role.
3, nanofiltration technology, its filtration pore size of 0.001 microns, filtration accuracy between ultrafiltration and reverse osmosis, the need to add electricity and pressure, the price is higher, but its price of the water purifier and water purifier principle were inferior to the ultrafiltration water purifier and reverse osmosis water purifier, so it is used less.
4, reverse osmosis technology, its counter-use of water from low concentration to high concentration of the principle, coupled with its filter aperture of only 0.0001 microns, so it can effectively filter out 99% of the pollutants in the water, and even the inorganic salts can be filtered out of a part of its also need to pressurize, add electricity, but its wastewater rate is relatively high, is not suitable for a large number of water purification work.
Water purifier recommended to choose Angel, Angel has a complete production management system, for quality and safety requirements are extremely stringent.
From parts to the whole machine, from R & D manufacturing to quality inspection factory, Angel in all aspects of the implementation of high standards and strict requirements of the control, adhere to provide consumers with high-quality water purification products, and therefore access to the U.S. NSF, Germany TüV, Switzerland SGs, the United Kingdom ITS, France BV and China's CQC certification of the six major authoritative bodies. Angel plowing water purification field for 33 years, participated in the development of 14 national and industry standards, with 768 patents, more understanding of China's water quality, research and development of water purification products more suitable for Chinese families, long-lasting reverse osmosis membrane was introduced, is to break the monopoly of foreign reverse osmosis membrane technology. Products sold in the United States, Japan and other 65 countries, won the global 200 million people choose.
The original long-lasting reverse osmosis membrane filtration accuracy of 0.0001 microns, is one millionth of a hair, can be enough to effectively remove dissolved salts in the water, colloids, microorganisms, organics, etc.; filtration is more thorough, after reverse osmosis and nanofiltration out of the system of water, clean, safe and excellent taste; can be completely removed from the water alkali and limescale for the north and west of the use of groundwater in the region For the northern and western regions using groundwater, the effect of water purification is very obvious, if the water pollution is more serious or unclear water quality situation is recommended to buy Angel water purifier, the big brand is more secure.
Angier's long-lasting reverse osmosis membrane can be used for up to five years, and has now won the world's top ten innovation patents, six international authoritative certificates. Equipped with aerospace-grade nano-whiskers after the activated carbon, nano-whiskers are the only antibacterial material used in manned spaceflight, three-dimensional four-needle structure to break through the cell wall, effectively inhibit the growth of bacteria, more secure than the traditional silver-ion antimicrobial way to effectively improve the taste.
