How about the mineralized drinking water machine in the communit

1.

If the water in the direct drinking machine in the community is maintained frequently by the manufacturer, it is clean and can be drunk, but it cannot be drunk for a long time. Although RO membrane can filter a lot of bacteria, impurities and chemical components, about 90% of the beneficial trace elements in the water are also filtered. The filtered water is called "soft water". The content of calcium, magnesium and other minerals is very low. Long term drinking may increase the risk of cardiovascular and cerebrovascular diseases

it should also be noted that the filter elements of these filtration equipment should be replaced regularly according to the regulations, which basically depends on the self-discipline of the operators. Whether the equipment itself is qualified or not and whether there is secondary pollution make the water quality safety questionable

extended data:

the water source of automatic water vending machine is tap water. After special filtration and other purification process, it becomes direct drinking water. There is no problem with the raw water. Excluding the secondary pollution factors of storage containers, the quality of direct drinking water also meets the sanitary drinking standard

the epidemic prevention department is not responsible for the supervision of the direct drinking water equipment in the community, and does not conct regular sampling inspection of its water samples. Only by the health supervision department, residents entrusted to test the water samples. The test report only has a legal basis for the water sample submitted for inspection. As for the water quality of the water dispenser, it can not be used as a basis

2. For the water dispenser, the most important thing is the raw water and the filter element. For the direct drinking water dispenser in the community, the raw water is basically the same as the tap water in your home. Then the next key is whether the filter element is qualified and whether the filter element will be replaced in time after the end of its service life.

3. District direct drinking water as long as it is regular proction, maintenance and inspection on time, is generally safe
if you want to drink directly, the key problem is whether the microbial indicators meet the requirements, and most water purifiers can't guarantee this. Even if there is no problem at the beginning, there will still be problems after a period of use. So if we can monitor the water quality in time, know what changes have taken place in the water quality and whether it is safe, it is very important
eco
Home water quality monitor is a home water quality monitoring expert from Silicon Valley. It can monitor the three important water quality indexes of total organic carbon (TOC), total dissolved solids (TDS), turbidity and water temperature in real time. The tested water is filtered to ensure the safety of water quality.

4. Hello, in fact, direct drinking water is safe in the community, as long as it is regular proction, maintenance and inspection on time, direct drinking water is safe. The following is the working principle of district direct drinking water. If the district direct drinking water machine is proced by a regular manufacturer, it will work in strict accordance with the following working principle, so the effluent quality can be guaranteed
1. The direct drinking water machine is connected with the water source by a hose. The water source enters the cold water tank and is led into the boiling water device. When the water level rises, a ball valve is used to control it to a limited height and the water source is automatically closed
2. The water source enters the cold water tank, the cold water electric control ball floats and turns on the power supply of the control circuit
3. When the power is on, the red indicator light is on, indicating that there is power. When the green light shows that the heating tube is working, boiling water will start in about five minutes. Meanwhile, cold water will continue to be added to the water heater, forming a working procere.

5. Technically speaking, the water proced by this machine is pure water, which can be directly drunk. But in practice, it varies from person to person
because the post activated carbon of purified water is required, but the water making equipment in some residential areas is not set up or can not be replaced in time, resulting in poor water quality. But bottled pure water will not have this problem, because it is made in the factory, and the process requirements will be higher
generally speaking, boiled purified water is recommended as the main drinking water. This kind of water has more reasonable molecular structure, and its osmotic pressure is similar to that of human body, so it is easier to be absorbed by human body. You can try what I said.

6. Generally speaking, e to the guarantee of the performance of RO membrane, the effluent quality of this kind of water machine is good and can be directly drunk
but when you use it, you should pay attention to the regularity of filter element replacement and the surrounding hygiene
then there is the sanitary condition of self provided buckets.

7. It's not safe. Many people touch the nozzle indiscriminately. It's very unsanitary. Needless to say, it's professional. That's all positive and unsanitary

8.

Harmful

a RO membrane is built in the direct drinking water machine for filtration. The RO membrane has a service life. If it cannot be replaced in time, it will cause secondary pollution. If the bucket is used for a long time, it is easy to breed bacteria, which is harmful to health

The RO membrane can filter a lot of bacteria, impurities and chemical components, but about 90% of the beneficial trace elements in the water are also filtered

the filtered water is called "soft water", and the content of calcium, magnesium and other minerals is very low. Long term drinking may increase the risk of cardiovascular and cerebrovascular diseases. In addition, the waste of resources is also a problem. The filtration ratio of direct drinking water machine is 1 (pure water): 3 (raw water), that is, 3 tons of tap water can be filtered into 1 ton of pure water, and the rest will be discharged into the sewer

the introction of direct drinking water dispenser is an agreement and cooperation between the proction enterprises and the community. The safety and health of the proct depends on the self-consciousness of the enterprises, so it is urgent for the government to strengthen the supervision. For example, the establishment of a third-party regulatory department, the direct water dispenser for the record, regular sampling of water samples; Relevant departments should punish the use of unqualified equipment, lack of business license and other violations; Advocate the installation of tail water recovery facilities

the property of the residential area should also assume the responsibility, send special personnel to clean and maintain the equipment, and try to put the direct drinking water machine in the indoor place. She also suggested that residents should not drink direct drinking water for a long time, instead of bottled water and tap water, or tap water filtered by activated carbon filter, so as to retain minerals in the water to the greatest extent and maintain their health

drinking water taboo

taboo 1, not completely boiled water

although the drinking water has been disinfected and sterilized, a variety of toxic substances can be separated from the treated tap water, and even some carcinogens still exist. So when boiling water, you should wait until the water temperature reaches 100 ℃ to drink. If you don't boil the water completely, the harmful substances will not evaporate completely. Drinking it will affect your health

No matter what kind of raw water you can't drink, because it may contain all kinds of bacteria, viruses or parasites that are harmful to the human body, drinking raw water can easily lead to physical changes, acute gastroenteritis and viral hepatitis, as well as parasitic infection and dysentery

Drinking water stored for too long will affect our physical development. After drinking, the elderly will accelerate the aging of the human body, especially esophageal cancer and gastric cancer, which is also related to this way of drinking water. Some studies have found that the water stored for too long contains more toxic substances, which will increase with the storage time

9. Yes, there is reverse osmosis RO membrane in the device, which can remove part of calcium and magnesium ions in raw water and rece the hardness of water
the degree of water softening depends on the performance of the membrane.

10. Look at the installation quality of drinking water dispensers in your community. As long as they meet the standards, according to the standards, the installation of drinking water dispensers in the community should completely meet the drinking water standards in terms of water purification. Most of the water purifiers meet the pure water standards and can be directly drunk.
