In rural areas, there is a lot of scale in the boiling water in one's own well. How can there be no scale?

In the past, wells in rural areas were essential wells for every household, mainly drinking water. Of course, if you have a vegetable garden at home, you can also water it with the water from the well. There are wells in almost every household here. Although tap water is installed at home, it is inconvenient to use. Generally, water is supplied for one hour from 9:00- 10:00 every day, and there is no water at other times. Once you miss it, you may not be able to eat water, so there is a well at home where you can drink water at any time. If the weather is cold in winter, the water supply is even less timely, and sometimes you can't eat water for a week.

In the past, the countryside used to take water from the springs of rivers or streams. After the late 1980s and 1990s, the family began to dig wells. When digging wells in the countryside, the villagers helped to dig wells together. Generally, a well here is 6.5 to 7 meters deep, which is enough for washing clothes, drinking water and drinking water for animals. But now all the wells are drilled by machinery, and the depth is more than 20 meters. Now, deep water wells are more delicious and sweeter than before. Mainly because the wells drilled in the past were shallow, people drank surface water, and the water pollution was relatively large. Now the wells are very deep, so it can be said that the real underground water source is less polluted.

There are a lot of water and dirt in many wells in rural areas, especially after the well water is boiled with a teapot. After a long time, there is a lot of scale under the teapot, and it feels dirty in vain. Even if you use vinegar to dissolve it, it will accumulate a little bit every time you boil water. After a long time, it will gather a thick layer of scale. In modern agriculture, this kind of water is called heavy water, that is, it contains many minerals, the most important of which are calcium bicarbonate and magnesium bicarbonate. This is also the main component of scale, and its stability is relatively poor. Once decomposed, calcium carbonate and magnesium carbonate are formed and gathered at the bottom of the teapot. There are more calcium and magnesium in the floating particles in this water, which can be used to grow crops such as corn, soybeans, vegetables and fruits, and it is better to supplement trace elements to plants.

How to deal with these scales in your well water? In general, some alum will be put in rural areas, which is a weakly alkaline substance that reacts chemically with calcium bicarbonate and magnesium bicarbonate, and then generates calcium carbonate and magnesium carbonate in their own wells, and the latter substance will sink in their own wells, which is a mineral that is extremely insoluble in water. In this way, the scale in well water is correspondingly reduced a lot. Although rural people sometimes don't understand its principle, after a long period of experience, the situation of excessive scale in well water is disposed of.

In short, there is scale in one's own well water, mainly because the water contains some unstable chemical minerals, such as calcium bicarbonate and magnesium bicarbonate, which form insoluble chemicals such as calcium carbonate and magnesium carbonate when heated, thus forming scale. According to the chemical principle, some alkaline substances can be put in for chemical reaction. After all, calcium bicarbonate and magnesium bicarbonate are weakly acidic when dissolved in water. In this way, in rural areas, alum with weak alkali solubility is generally selected. In rural areas, alum is mainly used as fried dough sticks. If you put alum in your own well, generally don't put too much, and then there will be no scale in the well water after chemical reaction. Alum contains a lot of aluminum ions, which is harmful to the health of the elderly. The amount of alum should be put according to the amount of dirt contained in your own water.
