There is a pure water machine called Bao mineralization

6. Never heard that drinking pure water will take away minerals from the body. That's what laymen say
however, what kind of water purifier is really not a good choice. Normal people don't need such trouble when drinking water
moreover, how do you know how pure this pure water is? How long has the water been stored? Where does this water come from
you don't have the test equipment, so you'd better not drink it
when the national water quality is up to the standard, the human body needs enough
if you have never used this water purifier, you can return it, so go to return it. General business has a few days return promise
just negotiate with them
hope to help you.

7. The water purification effect of a good water purifier should be very good. At present, the mainstream water purification technologies in the market are mainly divided into three categories: ultrafiltration, nanofiltration and reverse osmosis, of which ultrafiltration and RO reverse osmosis are the two main categories< Br > < br > generally speaking, ultrafiltration water purifier is relatively cheap, which can only remove large particles such as rust and sediment, but it has weak filtration capacity for small molecule dissolved organic carbon (DOC) and heavy metals< Br > < br > reverse osmosis water purifier, that is, RO membrane technology filtration, has a higher price than ultrafiltration water purifier, but it can effectively filter out harmful substances in water. The filtered water is basically pure water, and can well solve the problems of scale and alkali< Br > < br > nanofiltration is a pressure driven membrane separation process between reverse osmosis and ultrafiltration, which is used to separate small molecular weight substances from solvents, such as inorganic salts, glucose, sucrose and so on. In other words, it allows inorganic salts and some solvents to pass through the membrane, which is better than ultrafiltration water purifier, but worse than reverse osmosis membrane< Br > < br > therefore, if you want to buy a satisfactory household water purifier, choosing Angel reverse osmosis water purifier is your first choice in pursuit of quality< Angell is the first and only independent brand in China to focus on the field of drinking water purification. The company is positioned as a high-end water purification expert and has signed a contract with international superstar Gong Li as its global brand spokesperson. At present, angel procts have sold well in 65 countries such as the United States and Japan, and won the choice of 200 million people around the world. Founded in 1987, the company has 33 years of experience in water purification instry< br>

8. The water purifier is a kind of water purification equipment which uses multi-stage filter element for water purification. The physical methods such as filtration, adsorption and reverse osmosis without adding chemical substances are mostly used in the treatment. According to the water purification accuracy of water purifier, it can be divided into drinking water purifier, also known as household water purifier and laboratory water purifier which can meet the requirements of laboratory pure water quality. In view of the above information, you can choose the pure water machine of Wright Ryder to have a look, maybe you will have more harvest< Common sense:

is drinking purified water harmful to health

experts also remind the public to pay attention to buying bottled water with food hygiene license when using the water dispenser. A family of three is best to buy a small bucket and try to drink it in a short time. The water dispenser should be cleaned and disinfected regularly, and the "heating key" should not be turned on 24 hours. The water repeatedly boiled is not concive to health. It's best to drink flowing direct water

however, the biggest disadvantage of purified water is the removal of calcium, magnesium, fluorine, iodine, selenium and other essential minerals and trace elements. Some data show that the intake of calcium and magnesium in drinking water accounts for 5% - 20% of the total intake. Lack of this part of intake may affect the normal development of teenagers< Therefore, the relationship between purified water and health is controversial

purchasing skills:

1. Understand the water yield of water purifier

when purchasing water purifier, the first very important point is to understand the water yield of water purifier. Generally, the sales personnel of water purifier seldom tell customers the water yield and its meaning clearly, most of them just simply say how many gallons it is. In fact, the water yield of the water purifier does not refer to the tap flow, because the flow with the tap is the water stored in the pressure bucket and then flows out through the tap, so that flow is not the actual water making capacity of the water purifier. The actual water making capacity of the water purifier refers to the water making capacity of the RO membrane (such membrane is called 80gpd). If you want to see the flow of the water purifier intuitively, you need to turn off the switch of the pressure bucket, and then turn on the tap to see the real flow of the water purifier. Few people who sell the water purifier explain this to customers. After buying the water purifier, customers find that the water is not enough, so it is very important to choose a water purifier suitable for their own household flow

the water yield of the water purifier is expressed by GPD, such as 80g water purifier, which means that the water yield of the water purifier is 80gpd a day, equivalent to 12 liters per hour (about 3.75 liters per gallon). The pure water machine with 12 liters of water per hour, the drinking water and cooking water of a family of 3-6 people are completely enough. At present, the water proction of domestic brand water purifiers in the domestic market is 50GPD (50gpdro membrane is used, only a few brands such as Shihan use 80gpd membrane, because their company has the technology to proce RO membrane; Kangfule has 75GPD pure water machine

therefore, when purchasing a water purifier, you must understand the water making capacity of the water purifier. One is to choose the one suitable for your own household, and the other is the size of the water making capacity, which also reflects the price comparison of the water purifier

2. Choose the pure water machine with pump or without pump

there is a lot of publicity about the pure water machine without pump. First, learn about the pure water machine with pump and the pure water machine without pump. The pump of the water purifier has the function of boosting pressure. Because the principle of RO membrane is reverse osmosis, the precision is 0.0001 micron (one thousandth of a micron), so the water pressure into the RO membrane must reach about 0.4MPa, so the water purifier has a pump. The water purifier without pump adopts a kind of household ultra-low pressure membrane, and the water inlet pressure is smaller, about 0.2MPa. Because of the different performance of the membrane, the purification effect is not as good as that of the water purifier with pump
another point is that the domestic tap water pressure is not stable, so not all users can use pure water machines without pumps at home

in general, the domestic water purifier with a pump is convenient to use and can be used when the water pressure is low. The purification effect of the water purifier with a pump is better than that of the water purifier without a pump. Because of the performance of its RO membrane, basically the RO membrane with working pressure, the better the purification effect

3. Automatic flushing or manual flushing

the pure water machine has a flushing function, which is mainly used to clean the RO membrane, mainly to remove the scaling and microorganisms on the surface of the RO membrane after long-time use, and to clean and protect the surface of the RO membrane. This function in the home machine, cleaning is not necessary too often. In terms of practicability, environmental protection and economy, it is recommended to use the water purifier with manual cleaning control, because the water purifier with automatic control is automatically cleaned after starting up. Most of the water purifiers are basically washed once with 10 liters of water, and some of them are washed once they stop and start up again, with a time of 10-60 seconds. During this period, a lot of water will be wasted, and the RO membrane cleaning time of household machines can be controlled once every 3-7 days, Once 30-40 seconds or so, in case of special water quality, it can be cleaned once every 2 days. And the function of manual cleaning is also very convenient, that is, a switch, you can turn it on. Although it's a bit troublesome, it can save a lot of water resources<

4. Scientific selection of water purification equipment

4.1 water purification technology: most of the existing water purification technologies are the procts of science and technology in the last century, which can no longer meet the drinking water problems caused by the changes of living environment. Advanced water purification technology should pay more attention to the health, nutrition and activity of water while meeting the requirements of cleanness and safety

4.2 use cost: the selection of water purification equipment should not only focus on the price, but also the use cost. Many traditional water purification technologies consume electricity and water, which unconsciously increase the expenditure of users in the process of using. Water purification equipment with excellent performance price ratio should be more environmentally friendly procts with low power consumption or even no power consumption and no waste water

4.3 service life and price of consumables: the average cost of consumables per ton of water. The filter element of many traditional equipment has short life and frequent replacement, which increases the user's later use cost. Frequent replacement brings trouble and failure risk, and more likely brings health risk of purification equipment failure e to failure to replace the filter element in time. The use of revolutionary new technology makes the life of filter element longer and the cost of users really reced

4.4 service guarantee: water equipment is different from ordinary household appliances, and its normal operation is related to the health of users. Standardized service quality of aquatic equipment procts is an important reference index when we choose procts. Professional and responsible enterprises should provide the whole process service for aquatic procts, from installation and maintenance to periodic equipment inspection, free pre-sale measurement, etc., so as to ensure the health and safety of users.

Pure water contains less minerals, while purified water contains more minerals,

pure water refers to that after the filtration of reverse osmosis membrane (RO membrane) filter element, the original impurities in the water are blocked outside the membrane, and the filtered water is almost only water molecules, without any other molecules, ions and other substances

purified water refers to the purified water. All purified water can be called purified water

extended data:

pure water refers to H2O without impurities. From an academic point of view, pure water, also known as high-purity water, refers to water with high chemical purity. It is mainly used in the fields of biology, chemical instry, metallurgy, aerospace, electric power, etc., but it requires high water quality purity, so the most common application is the electronic instry

for example, for pure water used in power system, the impurity content is required to be low, reaching the level of "microgram / liter". In the proction of pure water, the indicators of water quality standards should be determined according to the proction process of electronic (Microelectronic) components (or materials). However, e to the complexity of microelectronic technology and many factors affecting the quality of procts, there is no complete water quality standard for a certain circuit proction obtained by process test
