Is bottled water pure water?
Question 1: 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.

Question 2: What are the ingredients of bottled water? Pure water on the market should not be called ideal mineral water (although it is mineral water, it is generally not as complete as the mineral water bought outside, such as lithium, strontium, selenium, zinc, bromine and molybdenum), but it is definitely not distilled, otherwise we can't afford it. The cost is about 150 yuan/10 liter. Distilled water has no nutrition. His production process is purification, such as disinfecting tap water first (introducing chlorine gas), and so on. . . .

There are about 20 to 30 steps. . .

Finally, the finished product.

Question 3: Is bottled water safe? At present, people drink bottled water the most. Drinking fountains (not water purifiers) can be seen everywhere in families, companies and units. After drinking, someone will call your door. Have you actually thought about how the water in this bucket came from? Is bottled water really safe to drink?

In recent years, the quality of bottled drinking water has been questioned frequently. The results of spot checks by local quality supervision departments show that the quality of bottled drinking water in China is worrying at present.

The bottled water market is chaotic and the industry is not standardized.

8 1 drinking water production enterprises were randomly selected in Beijing, and the overall qualified rate was 79. 1%. The products of 172 drinking water enterprises were randomly selected in Shanghai, and the qualified rate was only 60.5%. The outstanding problem is that microorganisms exceed the standard, among which the total number of colonies in 57 products exceeds the standard, and mold and yeast in 13 products exceed the standard. This has even affected the overall reputation of the bottled water production industry. The industry believes that in today's profit-driven, more and more unqualified manufacturers enter the bottled water industry, and some even directly fill tap water or raw water into barrels. There are no strict production conditions in the production workshop, blind pursuit of low cost leads to poor water quality, and unfair competition disrupts the bottled water market. I hope the relevant departments will strengthen supervision over this.

Drinking buckets have become "health killers"

According to CCTV's "Economic Half-hour" report, the General Administration of Quality Supervision, Inspection and Quarantine conducted random inspection on bottled water and found 45 unqualified products. After testing, the problem is not in the water, but in the bucket. According to the water delivery personnel, the buckets used by some bottled water outlets in the market are not disinfected after each recycling. In order to speed up the delivery of water, buckets are often filled with fresh water without disinfection. Generally, each bucket should be used at least three or four times, or even simply cleaned or disinfected in the case of dark color and poor transparency. According to reports, due to the high cost, buckets need to be reused, so the requirements for materials are strict, and PC materials need to be used for manufacturing. Bottles of bottled water are usually made of PET material. PET material is not suitable for making buckets, because it will produce harmful substances at high temperature and cannot be recycled and disinfected frequently. In the market, the current price of PC material is more than twice that of PET material. Due to the fierce competition in the market, some small enterprises have made up their minds about the cost of buckets. Replacing PC materials with PET materials has become a "simple" way to reduce costs, but this way directly leads to hidden dangers of bottled water, which seriously threatens human health and is extremely harmful.

Secondary pollution in the use of drinking fountains

Even if the purchased bottled water is qualified, there will be secondary pollution during use. The shelf life of bottled water is only 48 hours after opening the lid. Every time 1 liter of water is released, there must be 1 liter of air carrying bacteria and dust into the bucket. After a few hours, under certain suitable temperature and environment, the bacteria may reproduce again, and after more than three days, the bacteria will exceed the standard. After seven days, bottled water may have basically become stagnant water containing new pollutants, which is not suitable for drinking. The secondary pollution of drinking fountains mainly comes from water storage tanks, waterways and intelligent seats. If these parts are not cleaned and disinfected for a long time, they will deposit dirt and become hotbeds of bacteria and viruses. The researchers' experiments also found that the microbial contamination rate of bottled water and water samples at room temperature increased with time. There is nearly 1 0,000 ml of water in the inner container of the drinking fountain. At room temperature, the colony index was zero on the first day and climbed to 8000 on the 10 day. Coupled with the growth of bacteria in the "black barrel", drinking alcohol can cause many diseases such as digestive system, urinary system and nervous system. Do you feel at ease when spending money?

Question 4: Can bottled water be drunk directly? Generally, bottled water is pure water, which can be directly drunk 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.

Question 5: Do you often drink bottled water? Bottled water is best to avoid pure water. Without nutrition, long-term drinking will lead to system decline. Mineral water is the best choice, but it is also best to drink bottled water in a big bucket within a week, which will breed bacteria after a long time.

Question 6: Is bottled water pure water? The national standard for bottled purified water generally indicates that the shelf life of bottled water is 3 months, but this is in the unopened condition. If you open it, you can drink 15 days at most. It is understood that if the bottled water in Kaifeng is left for more than half a month, although the taste has not changed, the bacteria have exceeded the standard. Barreled water is highly purified during production and transportation. Generally, the quality of bottled water certified by QS can pass the standard. However, if the bottled water is opened for more than 15 days, the bacteria in the water multiply rapidly, which is easy to cause diarrhea.

Question 7: What's the difference between pure water and mineral water? Tap water is natural water treated by waterworks. After chlorination or purification, it is disinfected with chlorine for 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 and coagulates 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, stays for a certain period of time, then enters the clear water tank and is disinfected with chlorine gas.

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.

Question 8: 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.

Question 9: Does bottled water make money? What's the profit? Hello!

Many people have asked me this question. I have been making bottled water for 10 years. Let me tell you my heart so that you can avoid detours.

First of all, I want to tell you that the bottled water market is highly competitive, especially for water delivery workers. It is very hard (if you have the physical strength) to deliver water by yourself.

Secondly, you should locate your target customer base, and then locate your products (a water store has at most 3-5 brands, and some stores only sell 1 kind of well-known high-grade water, and the more kinds of water, the more difficult it is to manage). Product positioning is divided into three categories: a, high-end water stores; B, low-grade water shop; C, high, middle and low-grade water stores. There are generally three kinds of mineral water, mountain spring water and pure water on the market. Every kind of water has high, medium and low-grade brands, so customers can choose a representative brand with good reputation in the local area.

In addition, the most needed money for water store investment is empty barrels, generally between 30-30 50 yuan/month. I used to make an empty bucket named Kang Jiaquan. I can drink bottled water immediately, and the deposit is 30 yuan/month. Sometimes I can borrow it temporarily for a few days, depending on the conditions of the manufacturer. It is necessary to manage empty barrels. Some customers who confiscated the deposit ran away, and some asked the water delivery staff to sell the barrels outside. Reliable customers can borrow barrels, and unreliable customers don't borrow them. If you don't manage the empty barrels well, you won't make any money in the end, because all the money you started earning is invested in the empty barrels.

The market is so big that you can't do it for all your customers. Don't do it for customers who are too far away (pay attention to the ratio of water delivery time to how much money you earn). Doing business must be an accurate customer, and only 20% of customers will help you make money. Product positioning and target customers are very important. The store will start at around 20,000 yuan (the turnover of 200 barrels is 6,000 to 1000 yuan, the decoration is 3,000 yuan, the delivery tools are 2-3,000 yuan, and the water dispenser reserve is 1000 yuan, which requires other telephones and computers); There are also hundreds of thousands of large ones.

If you make a single kind of water, unless it is a brand water that can be used as a specialty store, I suggest that you diversify 3-5 brands and types of water (mineral water, purified water and mountain spring water) when the positioning of the water store is not very high, and the retail water price should also be considered comprehensively.

Take my Kangjiaquan as an example: retail price 10 yuan/barrel-purchase price 3.5 yuan/barrel-water delivery fee 2.5 yuan/barrel, as well as other expenses such as water dispenser cleaning, rental and telephone charges. Some fixed fees will decrease as your size increases, and everything is different in every place. Please summarize and analyze it when you do it.

Ensure that customers are not lost, provide good service, clean the water dispenser (regularly clean and disinfect once every three months), and deliver water in time.

Answer finished, I wish you a prosperous business! thank you
