Introduction Of Advantages And Disadvantages Of Pure Water Equipment Technology
1.Microfiltration is also called pretreatment technology, which is mainly used for coarse filtration.
Microfiltration technology is one of the four types of pure water equipment technology that is well applied and popular, and it is also a very early one. This technology is also very simple. The processing accuracy of its own technology is not high, generally between 0.1-0.3 microns. , To filter impurities in water, now microfiltration is a pre-treatment device for pure water equipment. The microfiltration uses PP cotton. After the water passes through the PP cotton, the impurities in the water are filtered out. The microfiltration will not change the structure and bacteria in the water.
Nanofiltration is the first choice for household water purification technology, and then reverse osmosis technology. Nanofiltration technology is not very mature, so it has not been vigorously promoted. The filtration accuracy of nanofiltration can reach the nanometer level, and the salt rejection rate is slightly lower than that of reverse osmosis. It is a membrane separation technology that requires power and pressure, but the technology is not mature yet and has not been put into use on a large scale. In the later stage, if nanofiltration technology is broken, it may replace reverse osmosis technology.
3. Ultrafiltration, also called mineral water equipment, ultrafiltration equipment
Ultrafiltration technology has a wide range of applications and high filtration accuracy. It is at a fine filtration degree of 0.01-0.1 micron. It is one of the six high-tech in the 21st century. It mainly uses membrane separation technology with pressure difference, which can effectively remove heavy metals, rust, sediment, suspended solids, colloids, bacteria, viruses, macromolecular organics, etc. in the water, and can retain some of the minerals that are beneficial to the human body. element. The mountain spring water and mineral water that we usually drink are produced through this process.
4. Reverse osmosis is called RO technology
Reverse osmosis technology can be said to have been famous for a long time. It is an ultra-high-precision pressure difference membrane separation technology that was exhausted by the United States in the 1960s. It is still one of the core technologies for the production of pure water in the world. Its main core element is the reverse osmosis membrane, the membrane pore size can reach 0.0001 micron. Under certain pressure, only pure water molecules can pass through the reverse osmosis membrane, and the raw water as long as the substance larger than 0.02 micron is inorganic salt, Heavy metal ions, organic matter, bacteria and viruses cannot pass through.
Daily Maintenance Of Water Treatment Equipment
Some minor faults of one kind or another may appear during the operation of the water treatment equipment, which may not affect the operation at that time, but if it is not handled in time, it will cause a major fault and cause a shutdown, and in severe cases, an accident may occur.
For example, loosening and falling off of bolts is a common phenomenon in parts with high operation and vibration, and tightening should be found at any time. If it is not discovered and handled in time, the lighter will cause greater damage to the equipment, and the severer may also cause casualties. In important connection parts, such as couplings, flanges, motor bases, etc., the bolts should be checked regularly with a wrench and tightened in time if they are loose. If the bolts in some parts are often loosened, to ensure safety, anti-loosening measures should be added, such as anti-loosening washers.
