The health risks of bottled water for long-term drinking water dispensers are as follows

SERENA 2020-05-27

1. Scale removal

Scale is easy to appear in water dispensers, especially in areas with high water hardness. Most of the white precipitates are carbonates. In fact, these salts exist in a very stable compound form, and there is no evidence that they are harmful to human body. However, the existence of these substances affects the efficiency of heat exchange. When scaling is serious, it will bring security risks. Therefore, the scale of drinking water machine should be removed in time.

The health risks of bottled water for long-term drinking water dispensers are as follows

2. "Thousands of boiling water"

This formulation is unscientific. The heating temperature of the water dispenser is generally 85 ℃ ~ 95 ℃, which does not reach the boiling degree. However, long-term heating will have an impact on the activity of water, so the longer the heating time is, the worse the activity of water is, commonly known as "aged water". Therefore, when you do not drink for a long time, you should turn off the power, in addition to saving power, you can also avoid the loss of water activity.

3. Nitrite in water dispenser

Because the water contains nitrate nitrogen, when the microbial pollution of drinking water machine is serious, it will promote the conversion of nitrate nitrogen to nitrite nitrogen. The WHO drinking water Directive states that infants will develop methemoglobinemia when the indicator exceeds 3mg / L in a short period of time. From the current research, there is not enough evidence to show that nitrite has a direct relationship with cancer.

4. Bacteria

When the water temperature in the water dispenser exceeds 60 ℃, ordinary microorganisms can be killed. When the temperature is above 80 ℃, bacillus can be killed in 10-20 minutes.

5. The material of heating the tank causes harmful substances to separate out

Most of the regular enterprises use stainless steel to produce heating tanks, which conforms to the relevant national health standards. The temperature of stainless steel is far higher than that of boiling water, so there will be no harmful substances. Some fake and inferior products use unsanitary materials. After being soaked in hot water, harmful substances can be dissolved, which will harm health.

6. The real health risk of using water dispenser is actually secondary pollution

Each water dispenser has five parts connected with the outside world, namely two faucets, water inlet, air outlet and sewage outlet. The secondary pollution of the water dispenser is mainly that the dust in the air carries a large number of microorganisms, algae, etc. with the air into the water dispenser, especially the air outlet and the drainage outlet are easy to form dead angles, where the microorganisms multiply in large numbers, and at the same time pollute the bottled water.

In foreign countries, the use of drinking fountains have professional guidance, must be regularly cleaned. Clean once every 2-3 months. When cleaning, professional personnel shall be found. Special micro acid cleaning and disinfection solution shall be used for self-cleaning. In addition, the water in the water dispenser should be used as soon as possible, especially in summer. It is better to use it in a week.

After reading, please remember to tell your family and friends that all problems are from the mouth. Remember to clean the water dispenser regularly to ensure the cleanness of the water dispenser, so as to ensure the cleanness of the drinking water, ensure the cleanness of the water you drink, and protect your body.
