Mineralized water in the community

1. District mineralized water machine what material less? From the water making process of most automatic water vending machines, there is "RO reverse osmosis", which is the necessary process to make pure water. After this treatment, water can basically be called pure water. However, this is only the intermediate process of automatic water vending machine, as well as high-density filtration, mineralization and other processes<

the water of the automatic water vending machine is made from tap water after being treated for many times. If some equipment is not replaced in time in the water making process, it is easy to cause secondary pollution, which may be worse than the untreated water. At the same time, although the automatic water vending machine has a special isolation area, the door of this area can be opened at will, so that the water outlet is easy to be exposed<

2. Generally, it is weak alkali treatment, Maifanshi mineralization treatment and selenium enrichment treatment

3.

1、 Pure water: pure, clean water without impurities or bacteria, such as organic pollutants, inorganic salts, any additives and various impurities, is the raw water that meets the drinking water health standards

Mineralized water: groundwater containing mineral salts, rich in essential major and trace elements

Purified water: it is made by electrodialysis, ion exchanger, reverse osmosis, distillation and other appropriate treatment methods. It is sealed in a container and contains no additives. Colorless and transparent, can drink directly

Mineralized water: mineralized water is groundwater containing minerals and salts

extended data:

according to the purification method, there are different kinds of purified water, for example, filtered water is treated by filtration reverse osmosis, and distilled water is treated by heating distillation. The filtered water after RO treatment contains a small amount of trace elements needed by human body, while the distilled water after high temperature treatment does not contain any trace elements

purified water does not contain any trace elements, but after treatment, the mineral elements such as calcium, magnesium, potassium and sodium needed by human body are significantly reced

4. Mineralized water is a kind of drinking water rich in essential major and trace elements, which is based on purified water, added with a variety of microelements and minerals, and automatically dissolved by mineralizer. Long term drinking mineralized water can supplement the trace elements and mineral nutrients in normal diet, so as to improve the nutritional status of human body. The mineralized water contains zinc, strontium, lithium, iodine, calcium, magnesium, metasilicic acid and other trace elements and minerals, which are completely ionized and can be quickly absorbed and utilized after drinking, and also contains rich dissolved oxygen. It is cool and refreshing, nutritious and hygienic, which makes up for the shortcomings of pure water. It plays an important role in promoting children's healthy development, enhancing children's intelligence, improving human immunity, preventing cardiovascular diseases, gallstones and kidney stones, osteoporosis, gastrointestinal diseases and so on. It is an ideal health drinking water for human beings.

5. Mineral water is formed by circulation in deep strata, which contains minerals and limited indicators specified by national standards. According to the difference of physical condition and regional drinking water, choosing the right mineral water can supplement minerals, especially trace elements. It is an effective way to drink mineral water in midsummer to supplement minerals lost by sweating

the nine limit indicators specified in the national standard include lithium, strontium, zinc, selenium, bromide, iodide, metasilicic acid, free carbon dioxide and total dissolved solids. One or more of them must meet the requirements of the limit indicators, and the required contents are (unit: mg / L): lithium, zinc and iodide ≥ 0.2, selenium ≥ 0.01, bromide ≥ 1.0, Metasilicic acid ≥ 25, free carbon dioxide ≥ 250 and total soluble solids ≥ 1000. Most of the mineral water in the market belongs to strontium (SR) type and metasilicic acid type

mineral water should be used instead of procts whose limit index exceeds the national standard. When purchasing, pay attention to whether the bottle cap is loose, whether the bottle body is transparent, and whether there are foreign matters floating. In addition, the surface tension of mineral water is high. A coin can float on the mineral water, but not on the common drinking water

according to the national standard for drinking natural mineral water in China, drinking natural mineral water is uncontaminated underground mineral water which is naturally gushed out from deep underground or artificially exposed; It contains a certain amount of mineral salts, trace elements and carbon dioxide gas; In general, its chemical composition, flow rate and water temperature are relatively stable in the natural fluctuation range& quot; National Standard & quot; In addition, the limit indexes of mineral water standard are determined, such as lithium, strontium, zinc, bromide, iodide, metasilicic acid, selenium, free carbon dioxide and total dissolved solids. If one (or more) of the indexes meets the above-mentioned composition, it can be called natural mineral water& quot; National Standard & quot; In order to ensure the safety of drinkers, the limit index and hygienic index of some elements, chemical compounds and radioactive substances are also stipulated. According to the water quality composition of mineral water, generally speaking, the beneficial elements contained in the boundary indicators do not have substantial physiological or pharmacological effects for occasional drinkers. However, if we drink mineral water for a long time, it has obvious nutritional and health care effect on human body. Taking metasilicic acid, lithium and strontium, which are the most qualified natural mineral water in China, as an example, these elements have biological effects similar to calcium and magnesium, which can promote the growth and development of bones and teeth, contribute to bone calcification and prevent osteoporosis; It can also prevent hypertension, protect the heart and rece the morbidity and mortality of cardiovascular and cerebrovascular diseases. Therefore, the content of metasilicic acid is one of the most commonly used and important boundary indicators for evaluating the quality of mineral water in the world. Lithium and bromine in mineral water can regulate the activity of central nervous system, and have the effect of calming mood and sedation. Drinking mineral water for a long time can also supplement the deficiency of calcium, magnesium, zinc, selenium, iodine and other nutrients in the diet. It also plays a good role in enhancing the body's immune function, delaying aging, preventing tumor, preventing hypertension, gout and rheumatic diseases. In addition, the vast majority of mineral water is slightly alkaline, which is suitable for the physiological characteristics of human body environment. It is concive to maintaining normal osmotic pressure and acid-base balance, promoting metabolism and accelerating fatigue recovery.

The water in the water vending machine is the purified tap water

The principle of water vending machine is to filter, permeate, mineralize, activate oxygen and sterilize the tap water, and filter out the bacteria and impurities in the water, so that the water quality can reach the national standard of direct drinking water

the key problem to ensure the water quality of the automatic water vending machine is the replacement of the filter element, because the filter element is the "heart" of the water purifier, which can effectively remove the floating impurities such as sediment, rust and moss in the water, and the filter element itself will absorb a lot of organic matter. If it is not replaced in time, it will bring hidden dangers to the drinking water safety of consumers

extended data:

precautions:

1. The filter element replacement of automatic water vending machine is related to the frequency of machine use and water proction, as well as the local water quality and seasonal changes

2. Seven of the filter elements need to be replaced and two need to be maintained. If they are not replaced, it will cause secondary pollution to the water

Do not blindly believe in the automatic water vending machine. Poorly managed water purification equipment also has a high risk of pathogenic microorganisms polluting drinking water, leading to the occurrence of water borne infectious diseases

The water vending machine instry is in a marginal state, and there is no clear department and corresponding management measures for supervision. If the direct selling manufacturers or sellers have complete proceres, it is difficult for the government departments to carry out more management, such as stipulating how long the manufacturers should clean or replace the filter element, and there is no clear regulation in this respect

7. 1. Mineral water is natural, mineralized water is synthetic
2. Mineral water is naturally formed underground mineral water, which is buried deep in the ground, circulating deep, unpolluted, and contains a certain amount of mineral salts, trace elements or carbon dioxide gas. Its water quality must meet the national standard for drinking natural mineral water; Mineralized water is synthesized by adding proper amount of synthetic mineral salt reagent into pure drinking water. There is no national standard
3. The content of minerals and trace elements in mineral water is stable, and the existing state is easy to be absorbed by human body. The content of trace elements in artificial mineralized water is easily affected by human factors, and the types of trace elements are not as many as those in natural mineral water.

8. Purified water refers to H2O without impurities, referred to as purified water or pure water. It is pure and clean water without impurities or bacteria, such as organic pollutants, inorganic salts, any additives and all kinds of impurities. The raw water is water that meets the sanitary standards of drinking water. It is made by electrodialyzer, ion exchanger, reverse osmosis, distillation and other appropriate processing methods, sealed in the container, and does not contain any additives, colorless and transparent
mineral water is natural gushing from deep underground or artificially exposed, unpolluted underground mineral water; It contains a certain amount of mineral salts, trace elements or carbon dioxide gas; In general, its chemical composition, flow rate and water temperature are relatively stable in the natural fluctuation range. Mineral water is formed by circulation in deep strata, which contains minerals and limited indicators specified by national standards. Mineral water is water containing dissolved minerals or more gases. The nine limit indicators specified in the national standard include lithium, strontium, zinc, selenium, bromide, iodide, metasilicic acid, free carbon dioxide and total dissolved solids. One or more of the nine limit indicators in mineral water must meet the requirements of the limit indicators, and the required contents are respectively (unit: mg / L): lithium, strontium, zinc, potassium Iodide ≥ 0.2, selenium ≥ 0.01, bromide ≥ 1.0, metasilicic acid ≥ 25, free carbon dioxide ≥ 250 and total soluble solids ≥ 1000. Most of the mineral water on the market belongs to strontium (SR) type and metasilicic acid type, and there are also mineral water with other mineral components.

9. I am a water plant chemist, in fact, for the human body, there is no specific standard for the selection of drinking water
there are purified water, mineral water, calcium ion water and natural purified water! To put it bluntly, it's all water filtered by RO membrane (an important part of water treatment)! Filtered water is pure water! After adding machine, the conversion is the so-called various functions of water! Therefore, the water sold on the market is synthetic@ Because pure natural can't reach the standard of bacterial count That is, unqualified)
distilled water --- many waterworks proce fake water! China's mainland does not add up to 5 water plants to proce distilled water
distilled water - the same as pure water! The purity is very high, but the conctivity is very low. It's not good for your health to drink it often
generally, the choice of water depends on whether it is a regular manufacturer! There is no QS, and then look at its implementation standard 17323-1998 (purified water standard), and then look at the packaging! Never choose sticker water (use trash bucket, bucket with your own name!) Generally, only black factories do this! Because, the water instry has unwritten regulations, each barrel, each household
on the contrary, in order to save money, some black factories buy a lot of black barrels without circulation! Trash barrel
regular manufacturers have abundant funds, so they won't proce miscellaneous barrels of OEM water I suggest that you drink the unpolluted mountain spring water in your hometown when you have a chance.)

10. The mineralized alkaline water of Peiyi brand intelligent water dispenser is an active water with health care effect soaked by the core patent "convenient real water core" with tap water as the source water. After testing, all the indexes are better than the national natural mineral water quality standard. The structure of water is weak alkaline (pH 7.6-8.2). The taste is fresh and smooth. The mineralized property avoids the disadvantages of pure water, and plays an important role in promoting children's healthy development, improving human immunity, preventing cardiovascular disease and gastrointestinal disease; Water is alkaline, which plays an important role in regulating the acid-base balance of human body, improving symptoms and diseases, removing excess free radicals, decomposing fat in human body and emulsifying cholesterol on blood vessel wall.
