It is generally difficult to avoid calcium and magnesium ions completely dissolving calcium and magnesium ions in the water after the water purified by the water purifier is boiled, so there is no way to filter it at present.
In fact, there is no need to be nervous, after this water is boiled, it does not have any toxicity to the human body***. is edible. If you don't like the water, you can put some tea leaves.

Generally speaking, white floaters are the product of water scaling, and the reason why there are white floats thrown after purification is because your water purifier cannot completely remove calcium and magnesium ions, that is to say, it is coarsely filtered, such as: simple filters with several filter elements, UF ultrafiltration water purifiers, their filtration pore size is larger than calcium and magnesium ions, so calcium and magnesium ions can easily pass through.
Because the water quality in some places is excellent, the concentration of calcium and magnesium ions is relatively high, and although the water filtered by the water purifier filters out the impurities and bacteria in the water, it retains the minerals and trace elements in the water, calcium and magnesium ions, etc., once the water is heated and boiled, these calcium and magnesium ions and minerals will react with water and air, and will form white floating objects or scale, which is actually a normal phenomenon.
The unfiltered water not only contains calcium and magnesium ions, minerals and other substances that are beneficial to the human body, but also colloidal substances and some impurities, bacteria, etc., such as suspended solids, rust, sediment, etc., and then these colloidal substances will be combined with impurities and tightly attached to the surface of the appliance, so after the tap water that has not been purified by the water purifier is heated, it is not easy to detect the abnormality, but after a long time, yellow scale will be formed.
It is recommended to use water purification equipment based on RO reverse osmosis membrane as the core filtration process, which can remove calcium and magnesium ions and have no scale after boiling.

Water purifiers and kettles often form scale, and after the tap water is boiled, there are white floating objects inside. Can you drink such water? Let's first analyze the "scale".
The composition of scale is the white floating matter (or precipitation) in the water is commonly known as scale, its main components are calcium carbonate, magnesium carbonate water boiled, the original dissolved calcium bicarbonate and magnesium bicarbonate, decomposed in boiling water, released carbon dioxide, into insoluble calcium carbonate and magnesium carbonate (they are the main components of limestone, dolomite) also precipitated, this is the origin of scale. In the process of crystallization and precipitation of scale, some crystal nuclei will settle down due to dense scale (hard scale), and some smaller crystal nuclei will float on the water surface if the scale formed is loose (soft scale). Pure carbonate scale is white, but there are often other impurities in the scale, so the color is different, such as mixed with rust scale, it becomes reddish-brown, which depends on the water quality of each place.
The classification of scale can be roughly divided into two types: hard scale and soft scale according to the different causes of formation and forming state. Hard scale: When the water contains impurities such as carbonate colloids, bacteria and organic matter, the carbonate is similar to the sand and gravel in the cement mortar, while the colloids, bacteria and organic matter are equivalent to the cement in the cement mortar.
Soft scale: Once viscous substances such as colloids, bacteria and organics have been removed (e.g. by ultrafiltration), even if the concentration of calcium, magnesium and carbonate ions in the water is high, it is carried out into a white and loose carbonate soft scale that is easy to remove, without hard scale.

Hello, the calcium content is too high. It's calcium carbonate.
Questions. So how to solve it?
This is not easy to do, and the water quality is difficult to change.
Softeners are OK.
Questions. Is that bad for the body?
There is not much harm.
It is generally said that the water is too hard.
Questions. Can a child drink it?
It's okay to boil the water and drink it.
No problem.
Questions. Bring it to a boil and drink.
Yes. That's the best way to do it.

Calcium and magnesium ions are completely dissolved in water and are difficult to filter out.
Water is hard, and the hardness of water is mainly formed by calcium and magnesium ions, and can be divided into two categories: temporary hardness and permanent hardness according to the composition of soluble salts contained in it.
In terms of the composition of water, as long as it is heated, no matter what type of water it is, it will produce scale.

This is normal:
1: Because in some places, such as the northern water, the concentration of calcium and magnesium ions is relatively high, and the water filtered by the water purifier still retains the mineral belt containing substances and trace elements, calcium and magnesium ions that are beneficial to the human body, etc., once the water is heated and boiled, these calcium and magnesium ions and minerals will react with water and air, and will form what we call white floating matter or scale. This is actually a normal phenomenon and a good phenomenon.
Two: However, the water that has not been filtered not only contains calcium and magnesium ions, but also colloidal substances and some impurities, bacteria, etc., such as suspended solids, rust and sediment, etc., and then these glue body substances will be combined with impurities and tightly attached to the surface of the appliance, so after the tap water that has not been purified by the water purifier is heated, it is not easy to detect the abnormality, but after a long time, yellow scale will be formed.

Summary. Dear, it is not recommended to drink, there is a white precipitate after boiling water, which may be the residual chloride ions in the water, it is recommended to filter the water before drinking.
Dear, it is not recommended to drink, there is a white precipitate after boiling water, which may be the residual chloride ions in the water, it is recommended to filter the water before drinking.
Is it harmful to the human body.
It's a floater. White floaters.
The white precipitate in boiled water is the hardness minerals in the water, mainly calcium chloride and magnesium chloride, which can lead to kidney damage and may even cause kidney failure.
Pro, boiling the water may make the water unclean, affect the taste of the water, and may also carry harmful substances, causing harm to people's health and early sleepiness.

This phenomenon is caused by too many calcium and magnesium ions in the water, which will lead to the formation of calcium carbonate, magnesium carbonate and other substances when heated. It is manifested as a scattered white precipitate or floating matter, which will not immediately form stubborn scaling, and this phenomenon itself will not be harmful to the human body, but it is unacceptable to the senses. The composition of tap water scale is mainly composed of calcium, magnesium, colloids and other substances, and the tap water with great hardness before purification is soluble in water before purification and filtration.
For example, after a long time of boiling water, sediment, rust, calcium and magnesium ions, colloids, heavy metals, bacterial corpses, etc., will attach to the bottom of the pot to form scale; After purification, the tap water with high hardness is purified by the energy machine, which filters out the colloids, sediment, rust, heavy metals, bacteria and other substances in the water, making calcium and magnesium ions insoluble in water. These are not visible in cold water.
When boiled, a compound is formed that floats on the surface of the water.
First of all, the white floats we see after the energy water is boiled are not released by the water machine itself, but by the original water. White floaters are actually minerals in the raw water.
The advantage of ceramic filtration technology is that it can not only remove silt, rust, sand, microorganisms, bacteria, heavy metals, oxides and other harmful substances in the water, but also retain trace elements and minerals in the water.
A glass of water that may seem crystal clear contains a myriad of substances that are invisible to the naked eye. Among them, they can be divided into hazardous substances and beneficial substances. Sludge, rust, sand, microorganisms, bacteria, heavy metals, oxides and other substances are naturally harmful to human health, while trace elements and minerals are essential elements for the human body.
Trace elements and minerals are characterized by being soluble in water, while silt rust is insoluble in water. In general, minerals and trace elements are invisible to the naked eye, but if the minerals are continuously heated, they will have a chemical effect, resulting in collision and recombination, and then precipitating in water-insoluble substances to form scale. Therefore, if you boil tap water and drink it directly, there will be a layer of hard scale at the bottom of the pot for a long time.

The white precipitate is limescale, and the main components of scale are calcium carbonate and magnesium carbonate, and the boiled water will produce a large amount of nitrite in the water after repeated long-term heating, these substances are not good for the body, you must know that the human body ingests too much calcium and is easy to get stone disease, and the high content of calcium ions in the blood will lead to muscle weakness, and nitrite is easy to cause cancer. >>>More
After the well water is boiled, there are a lot of white sediments and floating matter, which can be drunk, and the white sediment is calcium carbonate, which is usually called scale. The way to remove limescale is to add vinegar to the water and cook it for a while.
It can be drunk with confidence, and the water on the surface layer after precipitation is not harmful to the human body. >>>More
This question is a bit too broad, if from the perspective of drinking water safety, the water filtered by the water purifier is better, take the water filtered by the general ultrafilter and compare it with the boiled water. The rated pore size range of ultrafiltration water purifier is between microns, which can remove particles, colloids, suspended solids, residual chlorine, most heavy metals and organic matter in water, while boiled water can remove part of the scale, kill bacteria at high temperature, and evaporate residual chlorine, other toxic particles, colloids, rust, etc. can not be removed. In addition, the reverse osmosis water purifier has a higher removal rate, which can reach the point where other substances will not pass through except for water molecules. >>>More
