What happens when tap water turns milky white after boiling?

The milky white color of tap water is mainly due to the dissolution of air in the water supply network, which is broken down into tiny bubbles that cannot be seen by the naked eye under the action of pressure, and people feel that the water flowing out is milky white. As the bubbles disappear, the water becomes clear and does not affect the quality of the water.

Sometimes it is the property right unit that fails to regularly clean and disinfect the secondary water supply storage tank (box) according to the regulations, resulting in microorganisms exceeding the standard, and then treated with bleaching powder. After draining the water, it will appear slightly white-gray and can smell a slight pungent chlorine odor. This phenomenon is also not harmful to health.

If you see tiny bubbles gradually escaping from the bottom of the cup and gradually becoming clear and transparent in the next glass of water, it means that gas has been dissolved in the water.

The boiling water in tap water is milky white, which is what we call limescale. Tap water contains a lot of carbohydrates and various minerals, many of which are beneficial to the body. When the temperature rises to a certain level, they are separated in a granular state and observed with the naked eye.

and various minerals, many of which are beneficial to the body. When the temperature rises to a certain level, they will be separated in a granular state and observed with the naked eye.

The water pipe boiled milky white water, which was said to be mud. Tap water contains many carbohydrates and minerals, many of which are beneficial to the body and release particulate matter to some extent that is visible to the naked eye when the temperature rises.

Most of this situation is caused by the disinfectant in the water, and it is good to wait until the boiling water is cool to settle down.

When the tap water is boiled, it turns milky white, maybe there is too much bleach powder in it? Has there been a water or electricity outage at home? Generally, the water comes after the water stops, and the water should be left for a while before making drinking water. Otherwise, he will have a lot of sediment.

The tap water turns a frightening white, whether it is polluted.

When tap water is transported in a high-pressure closed pipeline, the air in the pipe will dissolve into the water due to high pressure, and when the tap water flows out of the faucet, the air in the water will be released due to the return to normal pressure, thus forming countless tiny bubbles, making the appearance of the water milky white, and after being placed for a while, it will be clarified and will not affect the drinking water hygiene.

Some residents report that the tap water is milky white, why does this phenomenon occur? First of all, it is necessary to determine whether the tap water is disinfected with bleaching powder, and some residents think that the milky white color of the tap water is due to the addition of bleaching powder, but in fact, this is a misjudgment. There are two main reasons for the milky white color of tap water:

First, in recent years, water supply enterprises have increased the service pressure of the pipe network, canceled the roof water tank as much as possible, reduced the secondary pollution of water quality, and forced part of the air to be dissolved in the water under the strong pressure inside the water supply pipeline. When the tap water is released from the user's faucet, the pressure disappears, and the air that is forcibly dissolved is quickly released from the water, forming countless tiny bubbles, resulting in the water color being milky white or milky, generally after dozens of seconds, the bubbles disappear, and the tap water returns to a clear state, which is a normal phenomenon in the urban water supply, and has no impact on the water quality.

On the other hand, as the traditional faucet is replaced by a mixing valve, the outlet filter of the valve has a filtering effect and a mixed air function, which plays a role in saving water.

It will also form a large number of bubbles when used, making the water white, and after the bubbles disappear, the water will also return to a clear state.

If the tap water is yellow or turbid, it is mainly because when the water supply is restored or the water supply valve is adjusted after the water supply is stopped, due to the sharp change in water pressure and the change in the direction of water flow, some rust attached to the inner wall of the pipe network is washed down, but the time is very short, which will cause the user to appear turbidity in the water for a short time. Users can turn on the faucet and release water for a period of time to drain the sediment or rust in the water supply pipe, and under normal circumstances, the water quality can return to normal in a short time.

In addition to the above reasons, there are the following aspects of abnormal water output from the user's faucet: first, the secondary water supply management unit does not clean and maintain the secondary water supply facilities in accordance with the regulations; Second, galvanized pipes are still in use.

or users of iron pipes, if they are not used for a long time, they may cause yellowing of the water due to corrosion.

Due to the need for sterilization and disinfection, tap water contains a small amount of bleaching powder, so the tap water is milky white;

Tap water comes from the ground, needs to be pressurized by a pressurized pumping station to be transported to each household, when pressurized, the pressure is very large, so that the air dissolves into the water, so the tap water will produce a large number of bubbles after being released, because the bubble volume is too small, so it appears milky white to the naked eye.

You're talking about the milky white color of tap water when it is first released, and then it clarifies for a while, right?

If it's the same as I said, then the tap water has just been added to bleach. The main ingredient of bleaching powder is a mixture of calcium hypochlorite, calcium hydroxide, calcium chloride and other ingredients. It is mainly used for disinfection, which is in line with national regulations, and the water company will also use it in accordance with national regulations.

So you can use it with confidence, but if you drink it, be sure to boil it before drinking.

The milky white color of tap water should be the effect of your water supply company adding various solvents when it is water quality treatment, which has not been completely digested and dissolved.

There are two main reasons why tap water is milky white:

1. Due to the need for sterilization and disinfection, the tap water contains a small amount of bleaching powder, so the tap water is milky white;

2. The tap water comes from the ground, and needs to be pressurized by the pressurized pumping station to be transported to each household, when pressurized, the pressure is very large, so that the air is dissolved into the water, so the tap water will produce a large number of bubbles after being released, because the bubble volume is too small, so it is milky white to the naked eye.

Hello, friend.

The main reason for the milky white color of tap water is that air enters the tap water pipeline, and under the action of pressure, the air and water are fully mixed to form a soda mixture.

When you turn on the tap, the tap water is milky milky soda mixture.

At this time, as long as the water is allowed to stand for a while, the air is released from the water, and the tap water will return to its original clarity.

If the renovation of the indoor pipeline is unreasonable, or there is a problem with the pressurized equipment in the building, there will be a phenomenon of mixing of steam and water.

The mixing of soft drinks and water will not affect the water quality, so users can drink with confidence. Thank you.

If the tap water appears milky white, it may be caused by sedimentation in the water pipe suddenly after the water stops.

It is normal for tap water to be milky white when it is released. This is because when the tap water is pressurized and transported through the pressurized pumping station, the air is dissolved into the water due to the excessive pressure, so the tap water will produce a large number of bubbles after being released, and because the bubbles are too small, they appear milky white to the naked eye.

The air enters the tap water supply pipe network, because the air cannot be discharged in the closed pipe, under the squeeze of tap water with pressure, the air and water are fully mixed to form a mixture of air and water, and the air is very fine bubbles in the water, so the water body is milky white, which is safe.

Some high-rise residential quarters, household water has to go through the second pressurization, the tap water supply pipe network into the air, because the air can not be discharged in the closed pipe, under the pressure of the tap water squeezing, the air and water are fully mixed to form a mixture of air and water, the air is very fine bubbles in the water, so the water body is milky white, it is safe.

Why does tap water appear milky white, because bleach is added during the treatment of tap water, and sometimes the water turns white, which is milky white.

Sometimes there will be a lot of bubbles in the tap water, and the water will produce a milky white color. When the water is placed in a container and left for a while, the gas in the water will come out and the water will become clear.

The tap water appears milky white and is bleaching powder. If the tap water is boiled with bleach, there is no milky white and it can be drunk, which is normal.

The milky white color of the tap water is due to the bleaching powder put in the tap factory, so the tap water will appear milky white.

Why does tap water appear milky white? The appearance of milky white is the initial stress, and this situation will occur.

Since the liquid dissolves into some of the gases when pressurized, the bubbles that precipitate when the pressure is released.

Air and pressure cause tap water to turn white.

Bleaching powder is present in tap water, and that milky white is bleaching powder.

It may be that bleach powder is put to filter impurities in the water.

It may be because there is too much bleach used for sterilization and disinfection.

These white precipitates are mainly calcium carbonate and magnesium carbonate, among others. Calcium bicarbonate and magnesium bicarbonate are found in tap water, and they are both soluble. As the water temperature increases, the bicarbonate becomes unstable and decomposes into carbonate, forming a white precipitate.

When the water is boiled, the bicarbonate in the water begins to decompose into calcium carbonate or magnesium carbonate, which precipitates out of the water in the shape of crystalline particles to form a white precipitate, which is what we usually call water residue, scale, and water alkali.

In the north, precipitation is relatively small, and people mostly rely on groundwater as their main drinking water. The deeper the well, the higher the mineral content of the water, and the more sediment there is in the water after boiling. This water can be drunk after being left in the sediment for a while, whereas the boiling water in the tap water has precipitation, which is also the reason for drinking.

The reason for the white substance produced after the tap water is boiled is that the carbon dioxide contained in the water escapes after heating, and the calcium carbonate in the water is insoluble in the hot water, and is released, forming a white precipitate.

This white precipitate is mainly due to the calcium carbonate precipitate in the water, which is a less soluble substance in the water that escapes to form a white precipitate after heating. In addition, other dissolved substances present in the water, such as sulfates, sulfides, etc., will also form white precipitates under certain conditions.

It should be noted that tap water contains a variety of different minerals and impurities, and the lead service of water sources varies greatly from region to region, resulting in different levels of minerals in the water, so the causes of white precipitate produced by boiling tap water in different regions will also be different.

In addition, it should be reminded that if there is a large amount of white precipitation after the tap water is boiled, it may be a problem with the water quality, and some impurities and harmful substances such as heavy metals are mixed into the water, which poses a potential threat to human health, and it is necessary to stop using the tap water in time and check the water quality.

Therefore, when we use tap water, we should pay attention to the quality and quality of tap water, as well as whether there is white precipitation after boiling, and deal with water quality problems in time to ensure that we drink safe and healthy water. <>

Summary. Dear, that layer of white stuff is limescale. The main components of limescale are calcium carbonate and magnesium carbonate.

Tap water, after a series of treatments, there are still some slightly soluble calcium bicarbonate and magnesium bicarbonate in the water, when heated and boiling, the unstable bicarbonate decomposes into carbonate, carbon dioxide and water, forming calcium carbonate and magnesium carbonate, which are insoluble in water, so they are precipitated and attached to the bottom of the pot (mainly precipitated) and around the pot, forming white scale.

Pro, after the tap water is boiled, the white nucleus floats are calcium and magnesium ion crystals. Tap water and well water contain calcium and magnesium ions to varying degrees. At room temperature, these ions are dissolved in water, and after the water is boiled, calcium and magnesium ions are precipitated, and the crystalline white float floats on top of the water.

These empty calcium and magnesium ions dissolved in water cannot be filtered out at room temperature, and the white floating matter formed is not harmful to the human body.
