Depending on the needs of the individual, each has its own benefits.
At present, the water purifier products on the market can be roughly divided into two categories, one is the water purifier represented by the RO reverse osmosis water purifier, and the other is the pure physical filtration product represented by the ultrafiltration machine.
RO comes from the English abbreviation, which translates to reverse osmosis. The direction of the flow of solution and water is from low concentration to high concentration, and the simple principle of reverse osmosis is to make the solution and water flow from high concentration to low concentration through pressure.
RO reverse osmosis was first applied to the aviation and medical fields, and the principle of reverse osmosis is used in the dialysis of kidney disease patients and the secondary use of astronaut urine. The reason is very simple, the pore size of the RO membrane pore is micron, that is, nanometer, and only water molecules and very few ions can pass through to achieve the strongest filtration effect.
Compared with RO technology, ultrafiltration membrane technology was applied to the water purification end earlier, and ultrafiltration was already serving wastewater treatment plants and other institutions in the early days, and ultrafiltration technology was also used in early water dispensers. Ultrafiltration filtration is a kind of membrane technology that relies on pure physical purification and filtration by pressure, and the current membrane pore size is rated in the range of microns, and the pressure difference is used for water quality filtration.
Ultrafiltration has its own advantages over RO water purifiers in terms of cost control, purification efficiency, and later maintenance costs, and ultrafiltration generally does not need to be energized and will not produce wastewater. If the water source situation in the area is relatively good, a water purifier using the ultrafiltration principle seems to be a better choice, even if it is a direct drink, there will not be much problem, so about the choice of ultrafiltration or RO reverse osmosis, you only needChoose the one that suits you.

1. Whether there is a product hygiene license approval.
The quality of the water purifier is very important, it is necessary to comply with the provisions of the measures for the supervision and management of drinking water sanitation, obtain the health license of the superior health supervision department, and after the identification of the technical supervision department, the water purifier that meets the national "drinking water quality standards" is trustworthy.
2. Whether it has safe and effective sterilization technology.
Water purification equipment uses two ways to sterilize, one is to add disinfectant, which can kill some bacteria, but the disinfectant contains trace amounts of chemical components that are harmful to human health; The second is ultraviolet sterilization, which is one of the most effective sterilization technologies recognized internationally.
Because ultraviolet sterilization is safe and efficient, it can quickly kill almost all bacteria, and ultraviolet sterilization uses physical principles to sterilize, without any chemical agents, and will not have any effect on the human body.
3. Choosing the right filter element is crucial.
The first generation of water purifiers are mainly filtered through activated carbon, ceramics, etc., which are easy to breed bacteria, pollute water sources, and cannot achieve the effect of clean water sources; The second-generation water purifier uses a variety of artificial polymer membrane filtration, which has a significant effect on removing harmful substances in the water, but its fatal flaw is to filter out trace elements that are beneficial to the body.
The third-generation water purifier adopts nanocrystalline filter technology, which solves the defects of the second-generation water purifier and filters out harmful substances and heavy metals in the water. Therefore, when you choose a water purifier, you must ask about the filtration technology and filter material used to see if it meets your own needs.
4. Whether it has a perfect after-sales service system.
After buying some brands, many consumers can't find the address of the maintenance service** or the repair service company, which makes consumers very helpless and causes a waste of resources, and many water purifiers have become furnishings.
The after-sales service of the water purifier mainly focuses on the replacement of the filter element, if the filter element is not replaced for a long time, it will pollute the water source, and the water purifier will also become a "sewage device". When choosing a water purifier, you must choose a manufacturer with perfect after-sales service, such as using a customer service system to track customer information and prompt customers and companies to replace filter cartridges.
5. The purchase performance ratio is high.
The structure of the water purifier is different, and the water purification effect is also different. Generally speaking, the structure of the primary filtration water purifier is simple, mainly activated carbon, its filtration capacity is limited, and it can only be used for coarse filtration, and the filtered water is best heated and boiled for drinking. Most of the first-level filtration water purifiers are low-grade water purification products, and the price of each unit is between more than ten yuan and 150 yuan.
The multi-stage filter water purifier has two stages of coarse filtration and a set of fine filtration, and the fine filtration mostly adopts a hollow fiber filter element, and the filtered water can be directly drinkable. Multi-stage filter water purifier is a mid-range water purification product, each priced between 300 yuan and 500 yuan, which can be accepted by the working class and used more by families.

In fact, the water purification effect has its own advantages, whether it is an ultrafiltration machine or a reverse osmosis purifier, the main thing is to protect the health of household drinking water, and the effect of reverse osmosis is slightly better.
1. The following two types of water purifiers are introduced.
1. Ultrafiltration water purifier.
The ultrafiltration membrane used in the ultrafiltration water purifier is ultrafiltration membrane filtration, and the membrane filtration method with the pressure difference as the driving force is ultrafiltration membrane filtration. There are about 6 billion micron micropores on the wall of each meter-long ultrafiltration membrane filament, and its pore size only allows water molecules, beneficial minerals and trace elements in water to pass through, so it can effectively intercept colloids, rust, suspended solids, sediment, macromolecular organic matter, etc., and discharge them when the ultrafiltration membrane is rinsed. When the water quality of tap water is seriously polluted, when the ultrafiltration membrane is used for a period of time, the trapped bacteria, rust, colloids, suspended solids, macromolecular organic matter and other harmful substances will adhere to the inner surface of the ultrafiltration membrane, so that the water production of the ultrafiltration membrane gradually decreases, which is easy to cause the blockage of the ultrafiltration membrane.
The characteristics of ultrafiltration water purifier are that the water output is large and the wastewater discharge is small, which can basically meet the purification of drinking water for the whole family, and is very suitable for the use of public families.
2. Reverse osmosis water purifier.
1) Reverse osmosis water purifier, the core key part is the RO reverse osmosis membrane, because its pore size is microns, the diameter of a bacterium is usually 1 micron, and the diameter of a virus is usually microns, so it can not only effectively remove harmful ions in water, but also remove all bacteria and viruses, and only allow water molecules to pass through. The reverse osmosis pure water function can filter seriously polluted tap water, such as benzene and ammonia nitrogen water pollution, to ensure the health of residents.
2) Due to the ability to remove all kinds of harmful impurities in the water, high efficiency and thorough removal, the RO machine effluent is the safest and most reliable drinking water at present. Compared with ultrafiltration, the reverse osmosis water purifier has obvious advantages in removing heavy metal ions that are very dissolved in water and harmful to the human body, and can remove carbon tetrachloride, chloroform and other harmful organic substances dissolved in water to the greatest extent.
3) Reverse osmosis machine is also called pure water machine, RO machine, it needs power supply, there is wastewater, the good is 1:1, most of it is 1:3, one liter of purified water is 3 liters of wastewater, the filtration is very pure, the TDS value is the lower the solid substance content, the better, and the taste is good.
Second, the advantages and disadvantages of the two types of water purifiers.
1. Reverse osmosis water purifier.
1) Advantages: water quality is safe, it can remove all kinds of harmful impurities in the water, it has a good effect on water supply special events, the taste of the water is better, it can reduce the hardness of the water, and the boiling water container does not scale.
2) The disadvantages are: pump, power consumption, electrical safety problems, many joints, high water pressure, relatively high failure rate and water leakage probability, complex structure, and more expensive.
2. Ultrafiltration water purifier.
1) Advantages: Generally, no pump is used, no power consumption, no electrical safety problems, few joints, low water pressure, relatively low failure rate and water leakage probability, simple structure, and cheap.
2) Disadvantages: the effect of removing chemical pollutants in the water is poor, the effect on the special event of water supply is poor, the taste of the water is slightly worse, and the hardness of the water cannot be reduced, such as the hardness of tap water is high, and the boiled water container may be scaled.

I'm in the water treatment industry. In Beijing, I have a good understanding of the water quality in Zhangjiakou (our boss is from Zhangjiakou and has done a lot of water plants there). It is recommended to buy a RO reverse osmosis.
Ultrafiltration membranes cannot be descaled. What needs to be explained is that there is nothing bad about the human body when drinking pure water for a long time, but there is no nutrition.
Only quench thirst.

Upstairs is basically correct. As for the statement that pure water is not nutritious, it seems that no doctor can let patients who lack trace elements drink more water.

RO is a membrane system, using the selective permeability of the membrane, which has a strong removal ability for CA MG ions in tap water, and the ion removal rate reaches more than 99%, but this is RO in the electronics industry, and the RO removal rate of the water purifier will not be so high, that is to say, it has the ability to remove some minerals, but it has not reached a very high level, UF is only a filtration effect, and it cannot go out of the ca mg in the ion state, which means that when you boil water, scale will be generated, I am doing electronic grade pure water, It's not a professional drinking water treatment, but if you're afraid of limescale, buy RO.

Buy it, there used to be an ultrafiltration one at home, but now the child is born and does not dare to use the ultrafiltered water. Because as soon as the ultrafiltered water is boiled, a layer of white scale floats. Not assured

Clean water molecules, as well as minerals in the form of ions in the water, can pass through ultrafiltration membranes due to their extremely small size; For example, dirty things such as rust and colloids are relatively large and cannot pass through the ultrafiltration membrane, so they are left in the membrane and washed away when the water is re-opened.

The water that goes up to the solar energy is filtered with a water purifier, can it reduce the dirt9 answers2024-03-31Formation of limescale in solar water heaters :
1. The continuous evaporation and concentration of water by heat causes the concentration of calcium, magnesium and salts in the water to increase, and when their concentration is exceeded, it will precipitate from the water to form a precipitate; 2. Water is heated, and bicarbonates are heated and decomposed, forming insoluble precipitates; 3. As the temperature increases, the solubility of some salts gradually decreases, and precipitates out. Impurities in tap water and dirt formed by the death of microorganisms in the long-term use of solar energy. These sediments, impurities, and dirt stick to the vacuum tube wall, forming insoluble scale. >>>More
