Question 2: Can the water purifier remove water and alkali? As we all know, the formation of scale is mainly due to the high content of calcium and magnesium ions in water, and insoluble precipitates such as calcium carbonate and magnesium carbonate formed by heating combine with suspended solids and colloids in water. Ultrafiltration membrane can effectively filter suspended solids and colloids in water, but it cannot filter calcium and magnesium ions. Ultrafiltration and pure physical filtration can not completely solve the scaling problem. Ultrafiltration water purifier adopts ultrafiltration membrane separation technology, which can effectively remove colloid and suspended matter in water. Therefore, after the water with higher hardness is filtered by ultrafiltration membrane, only some dispersed white powder of calcium carbonate and magnesium carbonate will precipitate when heated, and stubborn scale will not be formed. Ultrafiltration water purifier is characterized by retaining all minerals in water, which is more conducive to health. The white powder floating after the water is boiled is the mineral in the water. The turbidity of the experiment with soap also shows that the mineral content in the water is high. If you still find it difficult to accept the white powder precipitate, we suggest that you use a pure water machine to filter out all impurities in the water. The water purifier adopts RO reverse osmosis technology, which can effectively filter out all minerals in water. The only drawback is that the water output is very small, and the water output per hour in domestic or commercial pure water machine is about 20L. If you need a lot of pure water, you must use large-scale pure water equipment to solve it. This way is the most effective and the taste is relatively comfortable.
Question 3: Can the water purifier filter scale? The water purifier can filter the scale.
The scale is produced because the hardness of tap water is too high and it contains a lot of calcium and magnesium ions.
There are many kinds of water purifiers with different functions. General household kitchen water purifiers are mostly used to remove rust, sediment, bacteria, microorganisms and other harmful substances from tap water.
The special water softener is used for descaling, which mainly removes calcium and magnesium ions from water through ion exchange resin to reduce the hardness of water.
Soft water has a protective effect on hair, skin and clothes because it has no scale, and it will not cause pipeline blockage due to scale.
Question 4: Can the water purifier completely remove water-alkali scale? An unknown brand water purifier was installed before, and there was still a lot of scale after boiling water for less than half a year. Then I installed a Meg water purifier on the recommendation of my friend and used it for three years. It's fine now, just remind me to change the filter once every six months.
Question 5: Should there be water alkali in the water from the water purifier? The water purifier has water and alkali.
Scale is an oxide produced by the oxidation of beneficial mineral ions such as calcium and magnesium at high temperature.
If the filtered water does not produce scale under heating conditions or when mineral testing agent is dripped, it means that its minerals have been filtered out. Even if there are no minerals in the water people drink, there must be minerals in the water they excrete. Then, over time, human immunity is low, and osteoporosis will occur.
The so-called direct drinking machine should at least be able to sterilize, and ultraviolet sterilization is the safest and most efficient technology and will not pollute the water quality. At present, there are not many ultraviolet sterilization technologies, and there are not many safe and energy-saving ones.
Because I am in this line of work, I have some market research materials before I do this line of work. This is an objective reflection without any personal prejudice. Besides, since we live in a different place, it is estimated that you can't buy my things, so we are not interested. So, feel free to adopt it.
Question 6: Can tap water scale be filtered by water purifier? What brand is good? This depends on which type of water purifier you choose. RO membrane water purifier can be selected to solve the problem of direct drinking scale removal. The filtration accuracy of this type of water purifier is 0.00 1 micron, and the desalination rate is as high as 90%, which can effectively remove scale and reduce the water hardness value below the standard range. Another water softener can be used to remove scale. This kind of machine uses softened resin for ion exchange to achieve the purpose of descaling, which belongs to chemical descaling. Softened water is suitable for bathing, washing clothes and other domestic water. Both the water purifier and the water softener can remove scale, but the water purifier using ultrafiltration membrane can't remove scale, because the filtration accuracy of ultrafiltration membrane water purifier is 0.0 1 micron, which can't reach the required accuracy, so everyone should pay attention when purchasing water purifier. It is recommended to buy Huamai water purifier.
Question 7: Which filter water purifier has powerful descaling function? In addition to the powerful descaling function, only domestic brands can be selected. There is a household water purifier that specifically removes calcium and magnesium ions, and generally uses reverse osmosis. As for the scale, generally, the calcium and magnesium ion content is high to form scale, and silicate scale also exists, but it is relatively rare. We assume that your scale is a common calcium and magnesium ion. In fact, even silicate scales are recommended to be made in China. As for water purifiers, foreign products generally do not do too deep purification. They think that it is not good for people, or even harmful, if the water is deeply treated and filtered until there are no minerals. The water that enters the body will reach a concentration balance with our body fluids. If the water people drink is absolutely pure, not only can they not supply the minerals they need, but some ions in the human body will be dissolved by pure water and excreted. When I was studying, the teacher said, don't drink 27 layers of purified water. Once a foreign expert came to the company for training. He measured the pure water we drank in QCS barrels, and the conductivity was less than 30μS/cm. He said that this kind of water is not drinkable in their country. Anyway, let's go to the online mall. Foreign water purifiers, such as 3M, are generally filtered by two filter elements. The first filter element is PP cotton, which filters red worms, scale and suspended solids. The second filter element is sintered into activated carbon or other filter elements, which can basically filter disinfectants such as heavy metals, residual chlorine and chloramines, bacteria or microorganisms, volatile organic compounds or macromolecular organic compounds. I asked the engineer of a well-known brand water purifier company in China, and I said that the deeply purified water is not good to drink. He said that at present, we have many nutrient intake channels, and it is impossible to obtain essential minerals for the human body completely by drinking water. I tend to analyze and test water quality, so it's hard to say whether this answer is right or wrong. In addition to the water purifier, you can also choose a water softener, but this seems too expensive. In addition, if you choose a water purifier, it is also important to replace the filter element as required. If the filter element fails and the water purification effect cannot be achieved, it will be counterproductive. Someone has discussed this on the internet. You can have a look. Because the main filter element is not cheap, the water purifier can only be used to purify drinking water.
Question 8: Why is there scale when using the water purifier? The general function of household water purifier is "ultrafiltration adsorption", but it generally does not have ion exchange function.
Household water purifiers without ion exchange function can remove solids and even bacteria from water through multiple filtration and adsorption. But it can't remove soluble anions and cations in water, such as bicarbonate ions, calcium and magnesium ions, etc.
When water containing bicarbonate and calcium ions is heated, bicarbonate ions decompose and carbonate ions combine with calcium ions to form insoluble calcium carbonate precipitate, which is scale.
The water purifier with ion exchange function is not easy to scale under the condition that the exchange resin has not failed.
Question 9: What kind of water purifier can filter scale? It can't be filtered before the scale is generated, because the components of scale exist in water in the form of ions and can only be removed by ion exchanger.
Question 10: What water purifier can remove scale? Ordinary water purifiers that can produce water under tap water pressure generally cannot desalt, and the scale is formed by heating due to the high content of calcium and magnesium salts. Generally speaking, pre-installation and water purifier are commonly used scale inhibition methods, and scale inhibition is achieved through the filter material silicon phosphate crystal in pre-installation, or the multi-stage water purifier with scale inhibition level is generally equipped with a resin filter element in the structure, and the resin plays the role of replacing calcium and magnesium ions, reducing hardness and scale, or directly buying a pure water machine, which can desalt but has great accuracy. Generally, the water pressure of ordinary tap water will not come out, so it needs to be pressurized and electrified.
