Can the water from the water dispenser in the community drink
Phenomenon: Direct drinking water is cheap and known as multiple filtration.
Next to the security booth in the community, there is a direct drinking machine of a certain brand. According to the owner Mr. Wei, the direct water dispenser company installed this machine some time ago, and posted a notice saying that the machine has a separate water meter and electricity meter, and then used promotional activities to attract owners to apply for card consumption.
“You can get 20 yuan when you recharge the card with 150 yuan in cash, which is equivalent to buying a bucket of 7.5 liters (equivalent to 7.5 kilograms) of direct drinking water for only 1 yuan.” Wei The gentleman took out a water ticket and a gift list and said. If the owner spends money by himself, it will cost about 4 yuan to fill a bucket of 7.5 liters of direct drinking water.
In the past few days, the reporter visited some large communities such as Yinhai Avenue and Minzu Avenue and found that many communities have this kind of direct drinking machine, and its appearance is very different. It is almost like a vertical refrigerator, about 2 meters high. After coining or swiping a card, press the water outlet button, and water will flow out.
The instructions for these direct drinking machines indicate the water production process, showing that the direct drinking water is filtered through multiple procedures. For example, raw water (tap water) goes through seven processing procedures, including 5-micron PPF fiber, granular activated carbon, compressed activated carbon, 1-micron precision PPF fiber, post-installed activated carbon, and sterilization and purification device, and finally becomes ready-to-drink water.
Voice: Owners have praise and praise for direct drinking water
Community owners have praise and praise for such a direct drinking machine. Mr. Wei, the owner of Shenghe Greentown World, said that young people in the community are more likely to accept this direct drinking water and feel that the water quality is cleaner and safer. Older owners are worried that the water quality of the direct drinking machine is not guaranteed. When the merchants held promotional activities in the community, some elderly people quarreled with the promoters and prevented them from setting up stalls in the community to sell.
Although the direct drinking water is claimed to be filtered through multiple procedures, during the interview, the residents of the community did not have a particularly detailed understanding of the water quality, and they were not sure whether it was guaranteed. Some owners said, “The tap water that has been filtered through so many procedures should be cleaner.” There are also some owners who use “feeling”. The merchants used the water from the direct drinking machine to test and compare with ordinary tap water. Therefore, I believe that the water quality of the direct drinking machine will not be different now.
Aunt Lei from the living area of Taoyuan Road Business Hall said: “The water has no peculiar smell after being filtered and sterilized. It can be drunk directly and feels very fresh. The price is much cheaper than the bottled water sold on the market. I heard that water contains trace elements and other minerals, which are good for human health.”
The owner Mr. Wei believes that the water from the direct drinking machine is cheaper than the bottled water, which is unreliable. And the water purifiers he uses have to replace the filter elements regularly, but I don’t know whether the filter elements of the direct drinking machine are regularly replaced.
The businessman claims to take the initiative to publicize the test compliance report
According to an industry insider, around 2010, similar direct drink machines “bloomed everywhere” in urban villages in Nanning, but due to the habit of consumer groups Different, running the company business is bleak. Today, operators have changed their concepts and operate direct drinking machines in large or mature communities, which have a certain market.
“At that time, the direct drinking machine could not be operated. In addition to the consumption concept of the masses, the environment where the direct drinking machine was placed was relatively bad, and the water quality was not optimistic.” said the industry insider. In the interview, the relevant staff of the Municipal Health and Family Planning Supervision Office also said that the management of the early direct drinking machine business units was not standardized, nor could they be regularly maintained, and the water quality qualification rate was not high, so the mass utilization rate was low.
A picture is posted on the direct drinking machine in the living area of the business hall. The picture shows a direct drinking machine with the cover opened and a row of filter elements. Replace the filter element” etc. The reporter called the merchant on the direct drinking machine and asked how to ensure the water quality of the direct drinking machine. The man who answered the phone said: “We usually test and deal with the water volume. The direct drinking machine is controlled by the computer. Once the filter element is damaged, the computer will There will be garbled characters and cannot spit water.”
Mr. Liu, the person in charge of a brand of direct drinking machine in Shenghe Greentown World Community, showed the reporter an inspection report, which showed that all the indicators were qualified.
In the interview, most of the direct drinking machine business units said that the water quality testing of the drinking machine is usually carried out in half a month, and related maintenance such as replacing the filter element will also be supervised by the property and owner representatives, and signed Zhang Bang.
Statement: The health supervision department will randomly check the city’s direct drinking machines
According to the interviewed residential property staff, the drinking water safety must be shown before the direct drinking machine enters the community for operation. Product sanitation license approval documents and other materials. Mr. Liu, the operator of the direct drink machine, said that they have placed direct drink machines in nearly 100 communities in Nanning, but the company is not on the list reported by the Nanning Municipal Health and Family Planning Supervision. Mr. Liu showed the “Company Registration (Filing) Application Form” and said that he was applying for a business certificate. Another interviewed direct drink machine operator said that the address of his company is in Beijing, but he did not want to disclose the specific company name.
Wei Jianhong, chief of the third section of the Municipal Health and Family Planning Supervision Office, said that the community property should effectively manage the business units that enter the community to install direct drinking water equipment, and the municipal and urban health and family planning supervision offices are responsible for direct drinking water Daily supervision of water purification equipment and effluent quality. “In order to facilitate health supervision and social supervision, the operating unit is requested to report to the health and family planning supervision office as soon as possible with business licenses and other certificates.”
“The direct drinking water machine operating unit has the main responsibility for ensuring water quality, sanitation and safety. Regular maintenance and records are required, and water quality testing must be conducted at least once a quarter and publicized.” Wei Jianhong said, next, the Municipal Health and Family Planning Supervision Institute will conduct sampling tests on the water quality of the drinking machines in the city. Drinking water equipment that does not have any violations such as water-related product hygiene license approval documents will be dealt with accordingly. I hope that the owner will supervise, be responsible for the property, and self-discipline the industry, and refuse to enter the community without a license.”
Suggestion
Sanitation Supervision Department: It is best not to drink the water directly from the drinking machine
Wei Jianhong said that the autonomous region has not issued corresponding local hygiene regulations to manage the drinking machine, and the drinking water has not been included in the management of sanitation licenses. . At present, there are only 3 direct drinking machine business units in the city to report to the health and family planning supervision department.
In 2016, the Nanning Municipal Health and Family Planning Supervision Institute, with reference to the “Drinking Water Sanitation Standards”, conducted a random inspection of the effluent quality of 10 direct drinking machines of two brands in 3 units reported, and the test pass rate is 100%. However, “the direct drinking machine uses the municipal water supply as the raw water, which is purified and filtered to supply water to the users. The direct drinking water is neither mineral water nor pure water, and it is best for citizens not to drink it directly.”
Nutrition experts: Do not drink straight drinking water or pure water for a long time
Huang He, director of the clinical nutrition department of Guangxi Nationalities Hospital, believes that no matter whether the water contains “weak acid water” or “weak alkaline water”, The human body itself has the function of regulating the acid-base balance, which can maintain the stability of blood pH. In addition, the minerals in tap water are one of the sources of minerals in the human body, and the absorption rate of them by the human body is also high. If the filtering effect of some direct drinking machines has reached the level of pure water, that is, the water has been It would be a shame to remove the minerals.
Studies have shown that long-term drinking of “soft water” with a hardness of less than 8 mg/L (calculated as calcium carbonate) will increase the incidence of cardiovascular disease. Whether it is tap water or direct drinking water, for safety reasons, it is recommended to boil it before drinking.
