1, microfiltration technology mainly uses microporous membrane as medium, and the filtration accuracy is 0. 1 micron, which can only effectively remove suspended solids such as sediment and clay in water, but can not filter out macromolecular organic substances and inorganic salts. Because of its low filtration accuracy and short service life, it needs to change the filter element frequently, so it is not widely used.
2. Ultrafiltration technology is driven by pressure, and pollutants are filtered by ultrafiltration membrane. The filtration accuracy is 0.0 1 micron, so it can filter out most pollutants, including colloid, suspended matter and macromolecular organic matter, while retaining minerals. In view of its long service life, the filtered water can be directly drunk, and most manufacturers in the market use it in combination with other filtering materials, which plays an important role in kitchen water use.
3. Nano-filtration technology, its filtration pore size is 0.00 1 micron, its filtration accuracy is between ultrafiltration and reverse osmosis, and it needs electricity and pressure, and its price is higher, but the price and principle of water purifier are not as good as ultrafiltration water purifier and reverse osmosis water purifier, so it is used less.
4. Reverse osmosis technology, using the principle that water flows from low concentration to high concentration, has a filtration pore size of only 0.000 1 micron, which can effectively filter out 99% of pollutants in water, even some inorganic salts, and also needs pressurization and electrification, but its wastewater rate is relatively high, which is not suitable for a large number of water purification work.
Angel is recommended for the water purifier. Angel has a complete production management system and has extremely strict requirements on quality and safety.
From parts to the whole machine, from R&D, manufacturing to quality inspection, Angel has implemented high standards and strict checks in all aspects, and insisted on providing consumers with high-quality water purification products. Therefore, Angel has been certified by six authoritative organizations: NSF of the United States, TüV of Germany, SGs of Switzerland, ITS of Britain, BV of France and CQC of China. Angel has been deeply involved in the field of water purification for 33 years, participated in the formulation of 14 national and industrial standards, and has 768 patents. He knows more about the water quality in China and develops water purification products that are more suitable for families in China. The appearance of long-acting reverse osmosis membrane has broken the monopoly of foreign reverse osmosis membrane technology. Products sell well in 65 countries, such as the United States and Japan, and have won the choice of 200 million people around the world.
The original long-acting reverse osmosis membrane has a filtration accuracy of 0.000 1 micron, which is one millionth of that of hair, and can effectively remove dissolved salts, colloids, microorganisms and organic substances. From the water. The filtration is more thorough, and the water produced by reverse osmosis and nanofiltration is clean, safe and excellent in taste; It can completely remove water, alkali and scale. For the areas where groundwater is used in the north and west, the water purification effect is very obvious. If the water pollution is serious or the water quality is unclear, it is recommended to buy an angel water purifier, and big brands are more secure.
Angel's long-acting reverse osmosis membrane can be used for up to 5 years, and now it has obtained the top ten innovative patents in the world and six international authoritative certifications. Equipped with space-grade nano-whiskers and activated carbon, nano-whiskers are the only antibacterial materials used in manned space flight. The three-dimensional four-pin structure pierces the cell wall, effectively inhibits the growth of bacteria, is safer than the traditional silver ion antibacterial method, and effectively improves the taste.
