The composition and principle of RO water purifier

The water purifier is also called a water purifier. According to the composition, it can be divided into RO reverse osmosis water purifier, ultrafiltration membrane water purifier, energy water purifier and ceramic water purifier. Today, Xiaobian will introduce you to the RO water purifier. The composition of the RO water purifier The general reverse osmosis water purifier is filtered in the form of 5-stage filtration.
Primary filtration: Nowadays, the water purifier on the market generally uses 5μm PP cotton as the filter material to remove large particles such as rust and sand.
         Secondary filtration: Granular activated carbon is used as the filter material to effectively remove odor and odor and improve the purity of water. It also has a high removal rate for various impurities such as chlorine, phenol, arsenic, lead, and pesticides in the water.
         Three-stage filtration: There are 1μm PP cotton as the filter material, and some manufacturers use compressed activated carbon as the filter material. Enhance the effect of the first and second levels of filtration.
       Four-stage filtration: RO reverse osmosis membrane, a membrane made of a specific polymer material with selective properties. It can selectively permeate water and certain components in an aqueous solution under the action of external pressure, thereby purifying or concentrating and separating. Since the membrane pore size of the reverse osmosis membrane is very small, it is possible to effectively remove dissolved salts, colloids, micro-living, organic matter, and the like in water. It is the main component of the reverse osmosis water purifier, and its performance index directly determines the effect of the water purifier.
        Five-stage filtration: After-stage activated carbon, the main function is to improve the taste of water.
       RO water purifier water purification principle is simply that its technical principle is mainly the use of pressure gauge as the power of membrane separation filtration technology, this technology originated in the 1960s, was mainly used for aerospace research, with the constant technology Development and renewal, and slowly transformed into households, the current application of the field is more extensive.
      RO reverse osmosis membrane pore size is as small as nanometer (1 nanometer = 10-9 meters), is one millionth of the hair silk, can not be seen by the naked eye, bacteria, virus is 5000 times its. Under a certain pressure, H2O molecules can pass through the RO membrane, and inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses and other impurities in the source water cannot pass through the RO membrane, so that pure water and impenetrable can be transmitted. The concentrated water is strictly separated to achieve the purpose of purifying water.
The pure water from RO reverse osmosis water purification mechanism is fresher, healthier and safer than bottled water. It is widely used for water purification brands: it can be raw or boiled, and the most prominent in this respect. The characteristic is that the kettle or electric heating bottle will no longer be scaled; pure water is used for cooking, which is more sanitary and more delicious; bathing with pure water can remove impurities on the skin, moisturize the skin and play a natural beauty effect; The water of the machine and the water purifier can be supplied to the small household appliances such as humidifiers, steam irons, beauty instruments, etc., and there will never be annoying scales; water and ice making machines made by the water purification equipment using this technology Used together, the ice cubes are crystal clear and have no odor.
         Is drinking water made from RO reverse osmosis water purifiers harmful to human body for a long time?
       At present, there is a saying in the society: "The RO reverse osmosis water purifier filters out all the minerals beneficial to the human body in the water, and the purified water produced has no minerals. It is not suitable to drink more and will get rickets." According to E Xueli, a researcher at the Environmental and Health-related Product Safety Institute of the China Center for Disease Control and Prevention, this statement seems to have some truth, but after careful analysis, it will be found that there is no scientific basis for the above statement. He introduced that the role of water in the human body is: 1 food digestion, 2 nutrient delivery, 3 blood circulation, 4 waste excretion, 5 body temperature regulation. We have never heard of a person who is asking for water to supplement nutrition when a person lacks nutrition and vitamins.
       The body extracts only 1% of the nutrients and minerals in the water. 99% of the nutrients and minerals are obtained from whole grains, fruits and vegetables, and chicken eggs, rather than from the water. For example: molybdenum nutrition of the human heart, if you want to get enough molybdenum through water, drink 160 tons of water a day, but eat a potato, a handful of melon seeds can meet the body's demand for molybdenum. For example, the milk content of a cup of milk is equal to 1,200 cups of water, the iron content of a pound of beef is equal to 8,300 cups of water, and the vitamin content of a cup of orange juice is equal to 3,200 cups of water; Lack of nutrition, can only be supplemented by food, not by water. Moreover, the organic minerals in the water are not directly absorbed by the human body. Only after being absorbed by animals and plants, the human body can eat the edible parts of these animals or plants in order to allow the body to absorb.
       In life, we have heard that people lacking certain vitamins is supplemented by drinking water! No! Clean is a hundred times stronger than pollution. It is not wise to drink dirty water for a little bit of nutrients.
