Why are there many small bubbles in the bottled drinking water bought back?

Causes of bubbles on the wall of bottled bucket;

1, the gas content in water is high, and some gas overflows after standing, so bubbles are generated.

2. After filling, the bucket was shaken, and some gas in the water overflowed, resulting in bubbles.

3. The room temperature outside the water-filled area changes greatly, and the water temperature rises slightly after being left for a period of time. So there was a bubble.

4. The inner wall of the barrel is not very smooth, and there are tiny protrusions. After a long time, small molecules of water squeeze into micropores to form bubbles.

Barreled water is not suitable for direct drinking.

Food will go bad if it is kept for a long time, and water will go bad if it is kept for a long time, so people are usually used to eating fresh food and drinking fresh water, but bottled water is not suitable for drinking when it is fresh. The bottled water sold in the market, whether it is distilled water, reverse osmosis water, mineral water or other pure water, has been filtered and disinfected many times in the production process, but the final disinfection before filling usually uses ozone, so the bottled water just filled contains high concentration of ozone. Although ozone has a strong disinfection effect, its strong oxidation is very harmful to human health. When ozone is inhaled into the body, it will destroy vitamin E in the skin, causing wrinkles and dark spots on the skin. In severe cases, it will also destroy the immune function of the human body and induce lymphocyte diseases.

So if you drink bottled water when it is "fresh", you will undoubtedly take poison with you. The best way is to leave fresh bottled water for 1-2 days, and then drink it after the ozone dissipates. In addition, bottled water is not healthy water that can be safely drunk, especially bottled water that is used with drinking fountains. Faucets, water inlets and sewage outlets can easily let microorganisms and floating layers in the air enter the bucket, which will cause secondary pollution to the water in the bucket. In order to prevent drinking water that is polluted twice, the best way is to heat the water before drinking it.
