Generally speaking, incoming water and soft water are mainly suitable for northern areas, and their main purpose is to remove water and alkali scale. It uses resin to replace calcium and magnesium ions for dealkalization, and professional softening salt is needed to reduce the resin when the replacement reaches saturation. There is much water and alkali in the northern area, and the calcium and magnesium ions in the water exceed the standard. Thick "white ash" often appears at the bottom of the pot after boiling water. Drinking this highly alkaline water for a long time will easily lead to diseases such as kidney calculi and gallstones. In addition, with the gradual improvement of people's living conditions, many families have bought high-grade bathroom products and heating and hot water equipment. The biggest concern of these products is water and alkali. If the water used at home has high alkali content, it will easily lead to premature aging and dullness of ceramic bathroom products, inconvenient replacement and maintenance of heating pipes under the floor, blockage and explosion of water heaters, etc. Especially for friends who live in villas, one of the characteristics of villas is that they are relatively independent. Heating and hot water need to be solved by themselves and equipped with corresponding facilities. If it is best to use soft water for safety reasons, water softener is of course an indispensable choice. In addition, after using the water softener, washing your face and bathing with soft water can make your skin smoother and have a cosmetic effect. Why the skin of southerners is better than that of northerners is because the water in the south is mostly low-alkali soft water.
The water purification products on the market are complicated, so it is necessary to distinguish between water purifiers and water purifiers. When choosing a pure water machine product, first determine whether the product uses RO reverse osmosis membrane, and then see how many stages of filtration the product has. In addition to the appearance, we should also pay attention to the material technology of the water purifier to see if the surface manufacturing technology is exquisite. Some ultrafiltration membrane water purifiers can not effectively remove viruses and bacteria from water, and the purified water quality is far worse than that of reverse osmosis membrane water purifiers. When choosing a water purifier, the above problems should be taken as key considerations.
The two main components of the water purifier are RO reverse osmosis and high-pressure pump. RO reverse osmosis is imported, and high-pressure pump is imported and made in China. The quality of Taiwan Province Province is relatively good, and the quality of domestic pumps is up to standard. There is basically no problem, but it is ok. Other filter materials are basically the same, the first stage is PP cotton, the second stage is activated carbon, the third stage is resin, the fourth stage is RO reverse osmosis membrane, and the fifth stage is post-activated carbon.
The so-called water purifier is a water treatment equipment that uses RO membrane reverse osmosis technology for filtration, and its filtration aperture is only one tenth of a micron. RO membrane is a military technology developed by NASA to purify the urine of drinking astronauts. Later, it was applied to the civil drinking water treatment industry, and it belongs to the water treatment membrane with the highest filtration function in the world. Because the diameter of bacteria, viruses and heavy metals is larger than the pore size of RO membrane, bacteria, viruses and heavy metals can be eliminated in the process of water treatment, so that the drinking water can really reach the standard of direct drinking.
This situation can be basically divided into ordinary type, automatic washing type, indicator lamp type and computer control type. Users can choose to buy according to their actual situation.
It should also be noted that the function of the water softener is only to remove the water-alkali problem of the whole household water, but it can not remove bacteria, viruses, heavy metals and so on. At the same time, the water softener uses chemical methods to remove water and alkali, which has the safety risk of changing the composition of water body. Therefore, the water treated by the water softener cannot be directly drunk. The water purifier purifies water by pure physical filtration, which does not affect the safety of water quality and the health after direct drinking. On the whole, soft water removes water and alkali, and pure water removes bacteria, viruses and heavy metals, which complement each other. Therefore, experts in the water industry believe that "soft water+pure water machine" is the best equipment combination for water decoration.
