How much time boiled in boiling water?

The hardness of drinking water (ie total hardness) has a certain impact on human health. According to various domestic and international research data, the higher the hardness of drinking water, hypertensive heart disease, coronary heart disease The mortality and morbidity of diseases such as cerebrovascular disease and kidney stones are also higher.

boiled drinking water can reduce the water hardness. After different boiling times, boiled boiling water is placed in the cup and uncovered and poured into a thermos bottle for different periods of time, the hardness of the water will vary.

The boiling water will decrease with the extension of boiling time. If the hardness drops by 50%, it needs to be boiled for about 10 minutes. When the boiling water is poured into the cup, the hardness of the capping is more than that of the uncovered one. There is a significant drop in 1 minute after capping, and there is little change after 1 minute to 1 hour; the hardness of the boiling water has been reduced after pouring into the thermos bottle, and the hardness drops by 50% after 8 hours, and the change is not significant within 8 hours to 1 day.

According to the relevant experimental measurements, within 5 minutes after the water boils, the nitrite content in the water rises slowly and slowly rises for 5 to 10 minutes. The nitrite content in the water can be increased to 5 minutes after boiling for 15 minutes. 9 times.

Better within 5-10 minutes

In order to maximize the killing of bacteria and viruses in the water, to minimize the hardness of drinking water and to reduce the amount of nitrate in drinking water, The boiling time of boiling water is preferably controlled within 5 to 10 minutes. And how much water should be burned on the same day; the next day, the water must be emptied from the water in the kettle and the tea stove, and then drained and then filled with fresh raw water; the remaining water in the household thermos and cold bottles should be replaced every other day. Fill the newly boiled water with the remaining water and drink it.
