In recent years, everyone must be familiar with the water purifier, but do you know the water purifier? Do you know the basic principle? Do you know how to buy it? For these questions, Xiaobian introduces you to the water purifier. A little common sense. meaning Water purifiers can also be called filters, because the principle of his work is the principle of filtration, through the more accurate filtration accuracy to achieve the passage of harmful substances in the water, allowing healthy water to flow out, through the multi-filtration to achieve water purification purposes . principle The water purifier without electricity is purely physically filtered by the tap water pressure. The water purifier that needs electricity is used to increase the water pressure through the filter membrane, and it can be flexibly used according to the local water quality. The water softener uses cation exchange resin to remove most of the calcium and magnesium ions in the water, reduce the hardness of the water to remove scale, use activated carbon to adsorb residual chlorine and odor in the water, heavy metals and various chemical pollutants, improve the taste, and adopt ultrafiltration membrane technology to intercept the water. Bacteria, red worms, colloids, rust and sediment. How to buy The structure of the household water purifier is roughly classified into a coarse filter, an activated carbon adsorption, an ion exchange resin, a hollow fiber, and a reverse osmosis membrane. To purchase an ideal and practical water purifier, consider the following aspects: 1 Buy brand-name products. Users must understand the importance of product quality when purchasing a water purifier. The manufacturer of the water purifier must obtain the sanitation license from the higher-level health supervision department, and be appraised by the technical supervision department, in line with the national “Standard for Drinking Water Qualityâ€. 2 According to water quality purchase. The water hardness of different regions is different. The high hardness water quality in the north of China and the limestone area in the south have high calcium and magnesium ion content in the water, which is easy to scale. You should purchase an advanced filter water purifier with ion exchange resin filter. In urban water with chlorine, heavy color and odor, and organic content, you can purchase household water purifiers with more activated carbon. Because activated carbon has a strong adsorption effect on residual chlorine and heterochromatic odor in water, it has obvious removal effect on organic matter. For tap water purification with turbid water quality in urban and rural areas, household water purifiers with dual functions of coarse filtration and fine filtration should be purchased. Serious pollution in water requires thorough filtration of bacteria, viruses, odors, pesticides, heavy metals and other impurities in the water. If you do not need to drink it directly, you should purchase a reverse osmosis pure water machine.
