Tap water is a must in life, and the quality of tap water is also a major concern for many residents. With regard to tap water, many people will have some doubts. Below, Xiao Bian gave you an explanation of those questions about tap water.

4 questions about the answer to install the water purifier is very important (picture from the network)

1. Up to standard tap water = direct drinking water?

If the tap water reaches the standard of the new national standard, does it mean that it can be directly consumed? The answer is no.

There are two reasons: First, the use of chlorine to clean water in the production process of tap water can kill harmful substances such as pathogenic microorganisms, but adding chlorine itself can cause new chemical pollution. Another important reason is the long-distance pipeline transportation, the old rusted pipes, and the unclean or unsterile use of high-rise water tanks and complex reservoirs in long-distance pipelines, which can cause secondary pollution. Secondary pollution causes bacteria, viruses, and algae to multiply, together with the original chlorine and chlorides, rust, heavy metals, and radioactive substances that make the water turbid and smelly. The harm is endless. Therefore, tap water is not standard drinking water.

2. Why does tap water coming out of your tap come off, white, or yellow?

Fear: mainly due to the real burst pipe in the city water supply pipe, brought in the sand during the repair process.

Bleak: Mainly water is dissolved in the water supply pipe network and decomposed into tiny bubbles (not visible to the naked eye) due to the pressure. The close arrangement of the air bubbles feels that the outflowing water is milky white, and it stays still for several minutes in the container. After the bubbles disappear, the water will turn clear. This phenomenon will not affect the quality of tap water.

Yellowing: First, from the user's first watch to the user's home after the first valve to the user's galvanized pipe due to prolonged use or the quality of the pipe caused by the quality of corrosion caused by the secondary pollution of tap water.

3, boiled tap water, why there is a layer of white unknown material?

When the water is boiled, the originally dissolved calcium bicarbonate and magnesium bicarbonate decompose in boiling water to release carbon dioxide and become indissoluble calcium carbonate and magnesium carbonate (the main components of limestone and dolomite), floating first on the surface of the water. On the precipitation, this is the scale. This represents the hardness of the water. It has nothing to do with water quality and generally does not affect health.

4. What smell of disinfectant is there in the tap water?

It is normal for the tap water to have a significant disinfectant smell because the addition of bactericides is mainly chlorine, and the amount of additives is within the scope of national standards and is not harmful to the body.

To eliminate toxic impurities from tap water, installing a water purifier is a very good option. The water purifier can remove odors, toxic substances and other impurities from tap water and is a good choice for healthy drinking water.
