What is a water purifier?
Question 1: What is a water purifier? A water purifier is a device for purifying water.

There are many kinds of water purifiers.

Household under-cabinet water purifier;

Function: it can filter out impurities such as chlorine and rust in tap water, and finally flow out the purified and filtered water;

Installation location: under the cupboard basin; A special faucet for filtering water is installed on the basin; Provide pure water for the kitchen; It is convenient for washing vegetables, cooking, making soup and washing raw fruits and vegetables.

Features: no power supply is needed, and filtration is driven by water pressure. Generally, there are three to five stages of filtration, the first stage is filter element, the second and third stages are activated carbon, the fourth stage is hollow fiber membrane or British Dalton ceramic filtration, and the fifth stage is refined activated carbon, which is mainly used to improve the taste.

Household under-cabinet water purifier;

Function: filter out all harmful substances in tap water, and the produced water is pure water, which can be directly drunk. Mineralized filter elements such as medical stone can also be added, and minerals can be added to the water. Of course, such pure water is definitely better than the water filtered by ordinary water purifiers.

Installation location: under the cupboard basin; A faucet special for purified water is installed on the basin; Provide pure water for the kitchen; It is convenient for washing vegetables, cooking, making soup and washing raw fruits and vegetables.

Features: motor, power supply and water storage tank. Generally, it is a five-stage filtration. The first stage is filter element, the second and third stages are activated carbon, the fourth stage is RO reverse osmosis membrane for aerospace technology (this is the core), and the fifth stage is refined activated carbon, which is mainly used to improve the taste.

Household central water softener: household central water purifier;

Function: Soften ordinary tap water, remove water alkali and scale, and provide high-standard bathing and clean domestic water; Purify softened water for your whole family;

After using the water softener and water purifier, you will find that a good life cannot be separated from good water:

Laundry room: The clothes washed by your washing machine are brighter in color and more comfortable to wear. Reduce the amount of laundry detergent by 55% and increase the washing times of clothing fibers by 32%.

Kitchen room: after the glassware is cleaned, there are no water stains and spots, and the pots and pans are brand new.

Bathroom: Bathing will be a new silky feeling. Skin and hair quality will be significantly improved.

Features: resin filtration, regular salt addition to restore resin vitality.

Question 2: What do you mean by several levels of water purifier?

Question 3: What does the water purifier rely on to purify water? 1. The filter element plays a major role in the water purifier.

2. The filter element of the water purifier belongs to consumables and has a certain service life. The actual service life also depends on the local water quality and the frequency and quantity of use. Frequent cleaning is beneficial to prolong the service life of the filter element of the water purifier.

3. The main filter elements of household water purifier are as follows:

Polypropylene melt-blown filter element (PP cotton): it is mainly used to filter magazines, particles and sludge suspended in water. Generally, PP cotton should be replaced when it turns brown. If the central water purifier is not installed, it may be replaced in February or March. If a central water purifier is installed, it should be replaced once a year or so.

Activated carbon filter element: It can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has the function of decolorization and odor removal. The adsorption capacity of activated carbon will decrease after a period of use, so it needs to be replaced in time. The front activated carbon filter is replaced every 8- 12 months, and the rear activated carbon filter is replaced every 15- 18 months.

Ceramic filter element: mainly used for filtering, resisting bacteria and activating drinking water, harmful residual chlorine and suspended pollutants, organic chemicals, colors and smells. Generally, it can be replaced once every 10- 12 months.

Ultrafiltration filter element (UF) can effectively remove impurities and bacteria from water. Replace it every 12-24 months.

Reverse osmosis membrane (RO) Reverse osmosis membrane can intercept substances larger than 0.0000 1 micron, and it is the finest membrane separation product. It can effectively intercept all dissolved salts and organic matter with molecular weight greater than 100, and allow water molecules to pass through. It can be used for 1-2 years.

The ion exchange resin filter element replaces calcium and magnesium ions in water with sodium ions. It needs to be replaced in 3-6 months, but the filter element can be soaked in salt water to continue to use.

Question 4: What is a household water purifier and what are its characteristics? what

This is a household water purifier. What are its characteristics? Now introduce it. Household water purifiers are divided into RO reverse osmosis membrane water purifiers and UF ultrafiltration membrane water purifiers according to water purification technology. Its core component is the reverse osmosis membrane imported from the United States, which adopts the most advanced reverse osmosis water treatment technology in the world and does not use any chemicals and bacteriostats to prepare pure water. Household water purifiers are divided into RO reverse osmosis membrane water purifiers and UF ultrafiltration membrane water purifiers according to water purification technology. Reverse osmosis membrane water purifier, also known as RO reverse osmosis water purifier, takes the reverse osmosis membrane imported from the United States as the core component, adopts the world's most advanced reverse osmosis water treatment technology to prepare pure water, does not use any chemical agents and bacteriostats, and adopts physical and technical methods, which is harmless to human body and environment.

The water treated by reverse osmosis water purifier is clear, sweet, sterile, low in salt, free from scale and pollution, and contains certain trace elements and minerals. Suitable for drinking, easy to be absorbed by human body, activating human cells, promoting metabolism, enhancing immunity and resistance, healthy and safe, and suitable for areas with poor water quality. But the disadvantage of reverse osmosis machine is that it wastes water, and many enterprises are trying to solve it, but there is no good solution so far. In addition, some harmful organic substances in the water can't go out. In a word, it is not suitable for China, a country short of water.

General household water purifiers have no motor and power supply, and filter by water pressure. The effluent without water storage tank is usually normal temperature water. If you need hot water or ice water, you need to take over the wire machine/water dispenser separately. Its main function is to remove residual chlorine, impurities, odor, bacteria and other harmful substances in water, and filter out impurities, rust, some bacteria, viruses, colloids and so on in tap water. Some models have anti-scaling function. What are the characteristics of household water purifier? 1, PP cotton filter water purifier: a single-cylinder water purifier equipped with various PP cotton filters. The price of this machine is generally low, but the filter element is easy to block, the replacement frequency is high, and the filtration accuracy is not very high. This machine is only used for preliminary filtration of water, and cannot be directly drunk.

2.RO reverse osmosis pure water machine: The water purifier can completely remove harmful substances in water, and the purified water is pure water. The pressure of water is not enough for its working pressure, so a booster pump is needed, which requires electricity and pressure. Its biggest disadvantage is that there is a lot of waste water, and generally about 50% of the waste water should be filtered out. Its purification cost is high and water yield is low, so it can only be used to solve the drinking water problem.

3. Activated carbon filter screen: The super adsorption of activated carbon can remove different colors and smells in water, but it cannot eliminate bacteria and other harmful substances in water. The removal effect of simple activated carbon water purifier on sediment and rust is also poor.

4. Water softener: The biggest function of water softener is to soften the water quality, reduce the hardness of water, and then reduce the generation of scale. The general softening method is to replace calcium and magnesium ions in water with regenerated sodium resin. But it can't play a purification role and can't remove all kinds of harmful pollutants in water.

5. Ultrafiltration machine: Ultrafiltration water purifier can effectively remove sediment, suspended matter, rust, bacteria, colloid and some macromolecular organic substances in water, and can effectively retain some minerals and trace elements beneficial to children. Its advantages are long filter life, large water output, no need for power and pressure, and lower cost than other purification equipment, so it is very suitable for purifying domestic water. It can be done in the above way.

Question 5: What is a water purification pipe? It should be a water pipe that filters water, right?

Question 6: What is pure water? Broadly speaking, all pure water is called purified water, including pure water, pure water, mineral water and direct drinking water. Narrow water purification refers to the degree of water purification. For example, the water from the ultrafiltration machine is pure water, because it contains many impurities, especially water-alkali scale (calcium and magnesium ions), organic matter, chlorine, and odorous substances; In other words, the primary treated water is called clean water. What are pure water and mineral water? Pure water is purified by two-stage reverse osmosis, and its TDS value (total content of impurities dissolved in water) is 0, such as battery water; Mineral water refers to water rich in mineral elements.

Question 7: What is a dual effluent water purifier and what is its use? One machine produces two kinds of water: ultrafiltration water and pure water. The filter elements of the two kinds of water are different. The former is filtered by hollow fiber ultrafiltration membrane. The latter is a high-precision reverse osmosis filter element. Due to the valve for filtering water substances, two kinds of water quality can be customized.

Question 8: What are the advantages and disadvantages of the water purifier? Bottom line: improve tap water, you can drink it directly; Replacing bottled water is cheaper and more hygienic. At present, there are some hidden dangers in water quality in all parts of China. For example, the water quality in the northern region is generally hard, which is easy to cause lithiasis and affect human health; Heavy metals in South China generally exceed the standard, which is harmful to human liver, gallbladder and kidney. The water purifier can carry out targeted purification for different areas, so that all indicators of drinking water meet the hygiene requirements. ? At present, the main sources of drinking water in China are: boiled tap water; Bottled water is connected to the water dispenser; Buy bottled water directly in daily life. ? Analyze the advantages of water purifier compared with various methods: 1. After the tap water is boiled, it is still unable to remove pollution such as scale, heavy metals, volatile substances and bacterial corpses. ? Pollution 1: After chlorine disinfection, tap water can kill viruses and bacteria, but it can't remove scale, heavy metals and volatile substances. The bodies of viruses and bacteria still exist, and there will be residual chlorine in the water after chlorine disinfection. ? Pollution 2: Tap water is easily polluted for the second time after long-distance transportation through pipelines. Rust, sediment and bacteria will once again affect the quality of tap water, especially in high-rise residential buildings. Because of the secondary pressurization, there are generally water tanks on the roof, which will pollute the tap water entering the house with sediment, rust and bacteria. ? Therefore, tap water is basically boiled before drinking, but boiling can only solve the problem of bacteria, but can not solve the problems of sediment, rust, scale, heavy metals, volatile substances, bacterial carcasses and so on, so the water quality of drinking water will not be fundamentally improved if it is boiled. ? 2. Bottled water is connected to the drinking machine, which has high cost and short validity period, and is more likely to produce secondary pollution. ? Disadvantages 1: the cost of bottled water is high, about seven to ten yuan per barrel, and the cost is high. Moreover, most of these waters are tap water treated by large water purifiers or pure water machines, and few natural wells are available. ? Disadvantage 2: There are security risks. Barrels made of recycled plastic waste are polluted because they are reused by thousands of families without disinfection, transportation and treatment. At the same time, bottled water has a short storage time and is easy to deteriorate. When it is connected with a water dispenser, it will be polluted by pollutants in the air, so it is not an ideal drinking water solution. ? Disadvantages 3: inconvenient use, telephone reservation, waiting, 3. Bottled water is too expensive for daily use at home. Bottled water is listed as the daily water for a few wealthy families, but the cost of this method is too high, and the effect may not be as good as that of water purifier. ? 4. The water purifier can effectively filter various pollutants, reach the standard of raw drinking, and the cost is relatively low. ? Advantages 1: health and hygiene, reaching the standards of bottled water and bottled water. Water purifier is a pure physical filtration method, which can effectively remove various pollutants, such as bacteria, residual chlorine, heavy metals, scale (mainly calcium and magnesium, etc.). ), volatile substances, rust, sediment, etc. And the cost is much lower than that of bottled water, and the outlet water tastes good and can be drunk directly? Advantage 2: the water yield is large, which can be used for cooking and making soup. Convenient and fast, you can take it with you without waiting. It is the ideal drinking water solution for your family.

Question 9: What is the difference between a water purifier and a water purifier? There is no difference between a water purifier and a water purifier, just like tomatoes and tomatoes, with different names.

Water purifiers (water purifiers) are now mainly divided into ultrafiltration water purifiers and RO reverse osmosis water purifiers. Most kitchen water purifiers use ultrafiltration membrane technology. Compared with RO reverse osmosis water purification, ultrafiltration membrane water purifier can not only remove rust, sediment, bacteria, viruses and macromolecular organic substances from tap water, but also produce large amount of water and less waste water, and can retain minerals and trace elements in water.

There are also central water purifiers and central villa water purifiers different from kitchen water purifiers. The central water purifier can meet the water demand of the whole house, and the central villa water purifier can meet the water demand of villas or duplex buildings.

That's all I know. From the bottom of my heart, there are so many water purifiers on the market that you must keep your eyes open. If you want to choose a kitchen water purifier, you must choose a suitable brand factory and choose an enterprise product that has been doing this for a long time. It is unwise to only look at the brand, because some water purifiers have high brand awareness, but they choose OEM production.

Question 10: What brand of water purifier is good? What are the top ten water purifiers in China? Turn on the computer and use Baidu to search for "Top Ten Brands of Water Purifiers". 80 of the 100 water purifiers say that they are the top ten brands of water purifiers. Which one do you think is right? The top ten brands of water purifiers are actually a network term. The authority of the 10 brand certificate displayed by major manufacturers is actually not high, and it can be obtained for several thousand yuan.

At present, domestic brands of water purifiers are relatively deep, and many brands are small workshops that buy accessories and assemble them. Midea, Gree, Boss, Xiaomi and Amway are actually looking for other manufacturers to do OEM work. There are only a dozen manufacturers in Shenzhen who really independently design and produce water purifiers, because all the water purifier manufacturers in China are concentrated in Longgang District, Shenzhen. I know because I'm in the industry. )

Therefore, here are some "Top Ten Water Purifier Brands" with independent production capacity in China. These brands began to work hard in the water purification industry as early as five years ago or even ten years ago. You know, at that time, the household water purification industry had not yet started. At that time, the products produced by manufacturers were all laboratory-type, pure water machines or community automatic water vending machines. These brands are well-known manufacturers in the industry.

Manufacturer: Dr. Shui

In 2005, the brand of water purification for ten years was founded. Originally, it was a manufacturer providing bottled water production equipment similar to Wahaha Ipoh. In 2005, it began to enter the household water purification industry. CCTV is a listed brand and broadcast brand of CCTV, and a few brands have obtained the CE certification of the European Union, and they are the presidents of Shenzhen Water Purification Association in China. Hemei and Gree have cooperated, and the production capacity of water purification equipment and accessories in South China can rank in the top three.

Main business now:

Household water purifier, industrial water purifier, community water purifier, purified water production equipment supply.

Offline: physical franchise stores of household water purifiers, distribution points all over the country, etc.

Online: It seems that in order to protect the price of joining agents, there is no home water purifier in the online shop of Taobao Tmall JD.COM. In other words, consumers can only buy their water purifiers in local physical stores. If you buy it online, you can only find their manufacturer, which is more troublesome.

Manufacturer: Qinyuan

Qinyuan Group Co., Ltd. is a high-tech enterprise specializing in a series of elegant products of environmental protection Qinyuan, such as civil water treatment equipment, complete sets of industrial water treatment equipment and water treatment membrane. It is a national innovative pilot enterprise and a national intellectual property demonstration enterprise.

Online: There are stores in Qinyuan, Taobao, Tmall and JD.COM. Consumers are more convenient.

Other brands:

Midea, Gree, boss household appliances, etc. Leading enterprises in home appliance industry. Although their water purifiers are OEM, they are all the bosses in the home appliance industry after all. The quality is still guaranteed. Spend some time looking online, it is more convenient to buy at a low price. But consumers should be careful not to buy fakes, so try to buy them in their flagship stores, although they will be more expensive.

Xiaomi and Amway are not recommended, one is for mobile phones. One is for? By the way, what products does Amway make? Haha, anyway, it's all cross-industry and the water purifier products are also branded, which is more troublesome after sale.
