Usually, natural water exists in this way, and the cleanliness index of water quality includes various pollutants and Escherichia coli. Nemerow index method is one of the most commonly used methods to calculate comprehensive pollution index at home and abroad. The newly bought mineral water is unopened and still in a sealed state, and almost no bacteria will invade and destroy the water quality.
We once had the privilege of visiting the production workshop of Nongfu Spring. This treatment is not available to most people, just in time for the large-scale activity of Nongfu Spring at that time, called source-seeking activity. These photos were also taken at that time. The original picture, oh, now you should not be allowed to go in and shoot casually.
You have to change clothes, wear a protective hat and mask, disinfect your whole body and wear the same clothes as Zongzi. Anyway, the cleanliness of the factory is similar to that of the hospital operating room.
Put on a full set of clothes and go in for a visit. Most of the water intake points of Nongfu Spring are in several large areas. We are closest to Fusong Factory in Cuochaoquan, Jingyu County, Baishan City, and this factory is also the most advanced in equipment. The largest mineral water plant in the area, and there are several big factories nearby.
The incoming water is the natural spring water of Changbai Mountain. Fiona Fang, a few kilometers away from the water source, has no pollutants. The spring water in the water source area can be directly drunk. After the water is brought back, it has to undergo multiple filtration. In the above picture, quartz sand is filled to remove the large-particle impurities in raw water, and then it enters two other huge filtration devices for carbon filtration and precision filtration, where the small-particle impurities are intercepted.
The pore size of ultrafiltration membrane is slightly larger, which can let water molecules pass through and retain mineral elements in raw water to the maximum extent. After ultrafiltration membrane treatment, the water becomes cleaner and the pH value will not decrease. Ultrafiltration membrane requires high water source, clear water quality and less impurities. The last filtration procedure is sterilization. Through five checkpoints, the original direct drinking water became cleaner and the natural features were preserved.
No matter how good the water is, the bottle must be disinfected. A seemingly simple bottle also has many processes. Nongfu Spring has its own bottle cap injection workshop-independent purification workshop, the air purification level has reached the pharmaceutical industry standard, and there is also a bottle embryo injection workshop-which is fully automatic and has no personnel operation.
Empty bottles blown by the bottle blower are conveyed to the filling machine through the air conveying line. There are usually three production lines: 380ml, 1500ml and 550ml. At present, their filling machine is the fastest and most stable equipment in Northeast China. The last step is to put the water in the bottle.
Sealed natural water can be guaranteed for two years. As long as the bottle is not broken, the bottle will not be decomposed by the sun for two years.
Of course, it is best to drink the boiled mineral water in time, because bacteria multiply quickly in summer.

As a kind of food, Nongfu Spring bottled water must be marked with shelf life according to national regulations. However, food or articles that exceed this period may not be unusable. The key still depends on whether the item itself has deteriorated.

Is that weird? The canned water for ten years of military use is only pure water. It can be maintained by adding a little silver ion.
Pure water will not deteriorate. Unless it is caused by other external reasons, it will get worse.
It is impossible to have a two-year shelf life with your own technology.
The state has relevant laws as the basis.
If you notice that it's been two years.
Just drink tap water!
The spoilage of protein, fat and carbohydrate in general food, as well as the pollution caused by microorganisms, will lead to food deterioration.
The main chemical composition of drinking water is pure water, which does not contain the above three perishable nutritional metabolites, so the microbial indicators will be effectively controlled when producing drinking water.
Therefore, not only Nongfu Spring drinking water, but also other brands of drinking water can have such a long shelf life.
