Is bottled water generally pure water or mineral water? Hello, I'm glad to answer your question.
Barreled water is generally pure water. Rarely mineral water.
In addition, I just saw on Baidu that Laoshan spring water is generally mineral water, but the bottled water sent should generally be pure water, unless it is sent from the place of origin.
If in doubt, you can ask the owner of the water shop.
I hope my answer has solved your problem. If you are satisfied with the answer, please adopt it.
What's the difference between pure water and mineral water? Tap water is natural water treated by water plants. After chlorination or purification, it is used for chlorination of drinking water. Untreated source water is not tap water and cannot be drunk.
2. Pure drinking contact refers to the water that meets the hygienic standard of drinking water and is sealed in a container without adding any additives through electrodialysis, ion exchange, distillation and other appropriate treatment methods.
3. Mineral water is unpolluted underground mineral water that naturally gushes out from deep underground or is exposed artificially; Contains a certain amount of mineral salts, trace elements or carbon dioxide gas; In general, its chemical composition, flow rate, water temperature and other dynamics are relatively stable within the natural fluctuation range.
Second, the difference between tap water, pure water and mineral water
From the definition, we can basically observe the difference between the three. Here, we will explain the differences from three aspects.
1.
Tap water is sent to the waterworks by natural water flowing through the water pipe (or pumped and pressurized by the first-class pump house). Before entering the water purification structure, coagulant aluminum sulfate or polyaluminum chloride is added, lime is added to improve the alkalinity of raw water, and chlorine gas is added in advance (depending on the quality of raw water). After that, it enters the grid reaction tank for coagulation to form alum flower, which flows through the honeycomb inclined tube sedimentation tank for precipitation and separation, then passes through the gas-water backwashing filter, enters the clean water tank, and is disinfected with chlorine after staying for a certain period of time.
Purified water is the raw material that meets the sanitary standard of drinking water. Most harmful, toxic and odorous substances such as heavy metals, trihalomethanes, organic substances, radioactive substances and microorganisms are removed by various processes to eliminate the direct and potential harm to human health, and then bottled and sold to people for drinking.
The formation of mineral water is complicated. It refers to a series of physical and chemical actions such as leaching, anion exchange adsorption, biogeochemistry, etc. when groundwater flows through rocks containing different components. Trace and main components in rocks enter groundwater and are enriched to some extent, forming various types of mineral water.
2. Differences in composition.
Tap water is treated by the water supply company for life and production. It contains various substances such as dichloride, plasma such as calcium, magnesium and chlorine, trace bacteria such as Escherichia coli, and other solutes. Among them, China's national standard GB5749-85 stipulates that if it is only used as the source water of drinking water, after chlorination, the average number of Escherichia coli per liter shall not exceed 10000, and after purification and chlorination, the average number of Escherichia coli per liter shall not exceed10000.
Pure water is used to purify raw water by distillation, reverse osmosis and other technologies. While removing harmful substances, it also removes almost all trace elements and minerals beneficial to human body. It contains no impurities, is non-toxic and sterile, and is easily absorbed by human body.
Mineral water is different from tap water and pure water. It contains more than 20 kinds of trace elements and minerals such as lithium, strontium, zinc, iodine and selenium, and some are also rich in macro elements, such as gallium, magnesium, potassium and sodium plasma.
3. The difference between drinking methods
Tap water should be boiled to drink. This can kill the bacteria inside and remove most volatile organic compounds (such as trihalomethane) after boiling.
Pure water is water that can be directly drunk, and it has nothing to do with heating and boiling. Generally, drink cold in summer and drink more after heating in winter.
Mineral water is generally not heated, but can be heated slightly, preferably not boiled. Mineral water is ionic at room temperature because it contains a lot of macro elements such as calcium and magnesium and has a certain hardness. Calcium magnesium plasma is easy to form scale with carbonate after heating and boiling, so the best drinking method of mineral water is to drink it directly at room temperature.
Can bottled water be drunk directly? Bottled water is generally pure water, which can be drunk directly after filtration.
Barreled water refers to pure water or mineral water treated by modern industrial technology (reverse osmosis, electrodialysis, distillation, resin softening, etc.). ) and filled into PC barrels through the filling production line. It is divided into pure water, mineral water and mineral water (made by artificially adding mineral residues in pure water).
Compared with the maturity of drinking fountains, the cleaning and disinfection industry of drinking fountains has just started, and it needs large-scale operation and technological innovation. In today's fierce competition in the drinking water market, the cleaning and disinfection of drinking fountains, a special supporting service to help consumers eliminate health blind spots, is expected to become a new hot spot.
How much does it cost to earn money in bottled water? A bucket of water in 5 yuan, the price of a bucket of water is 0.2 yuan, plus a bucket of 0.5 yuan, and other electricity, consumables and labor costs are 1.5 yuan, which can be converted into 2.8 yuan.
Barreled water refers to pure water or mineral water treated by modern industrial technology (reverse osmosis, electrodialysis, distillation, resin softening, etc.). ) and filled into PVC barrels through the filling production line. There are many kinds of bottled water sold in the market, including pure water, mountain spring water, mineral water, mineralized water, activated water and ionized water. Due to different water sources and different production processes, the types and contents of trace elements in different kinds of bottled water are also very different.
What's the difference between pure water and mineral water? Pure water is filtered water, which basically contains only water. There are no minerals, molds, bleaching powder, etc ... Mineral water is mountain spring water or deep groundwater, which contains many minerals and trace elements necessary for human beings, animals and plants for hundreds of millions of years. Pure water was originally used in industry. For example, the battery liquid is pure water (distilled water is also a kind of pure water), and now the filter element technology has passed the standard, and it is also very pure after filtration. Now the pure water sold outside is filtered water)
How is pure water produced in large quantities? What's the difference with mineral water? Pure water is made of water treatment equipment. Gong, for example, the relatively large wading manufacturers in China, such as Master Kong, Nongfu Spring and Mengniu, all use water treatment equipment to make pure water. And then carry out other processing.
Pure water is tap water purified by multiple layers. After passing through the reverse osmosis membrane, most minerals are filtered out. Mineral water is of course rich in minerals. The difference between them lies in the content of minerals.
Recently, however, an energy water machine appeared in the market. Mineralized filter elements or other things were added to the water purification equipment to increase the contents of minerals and other trace elements in the water. Specific information can be searched in Dahe Water Network.
What's the difference between pure water and mineral water? Mineral water is drinking water containing minerals. Pure water generally refers to drinking water that does not contain various mineral ions and chemical ions. The advantage of mineral water is that it contains mineral elements needed by the human body and can supplement the body's needs. The disadvantage is that these elements are not always needed, and sometimes they may be useless. The advantage of pure water is of course clean and hygienic, but long-term drinking is not good for your health.
Pure water is made from rivers, lakes and tap water through distillation, electrodialysis, ion exchange and reverse osmosis. Sterile purity is achieved through complicated deep purification procedures.
Mineral water is unpolluted underground mineral water that naturally gushes out from deep underground or is exposed artificially. Mineral water contains many minerals and trace elements beneficial to human body, such as lithium, strontium, selenium, zinc, bromine and molybdenum. , has a strong physiological function and has a certain health care effect on the human body. In general, the chemical composition, flow rate and water temperature of mineral water are relatively stable within the natural fluctuation range.
The similarity between mineral water and pure water lies in safety and hygiene. The biggest difference is the content of mineral elements. Pure water removes all kinds of elements in water to the maximum extent, leaving only water molecules, while removing harmful substances and beneficial substances; Mineral water, on the other hand, retains some substances and trace elements in the water to a certain extent.
Drink bottled water often, ok? 10. Drinking bottled water often is not as good as drinking boiled water.
There are several reasons:
1. bottled water is actually mineral water, not pure water, or long-term drinking will inevitably increase impurities in the water. The water purification device of drinking fountains sometimes has a layer of mud, which is sediment.
2. Many people lack the awareness of disinfection of drinking fountains, and even if they do, they don't know where to disinfect. Long-term humid environment, it is easy to breed bacteria
The cost of boiled water is much lower than that of bottled water.
However, there are several points for attention when boiling water: 1. Don't boil water for the second time. It's better to wait a few minutes after the water is boiled.
That's all I can think of for the time being
How to distinguish pure water from mineral water? Just use the TDS test pen, a special water quality testing tool of Qing Changde Noel Electronics. The TDS value of pure water is generally 10~25ppm, and that of mineral water is generally 40~ 120ppm.
Simple method: take a small amount of pure water and mineral water respectively, and after heating and evaporation, see if there is white residue or mineral water.
