In the 1870s, American scientists revealed to the world the carcinogenic problems of chlorine-treated tap water. After that, the United States began to popularize household terminal purification devices to deeply purify tap water. A household water purifier was born.
The tap water passes through the water plant and the pipeline to the residents' home. Water plants are generally sterilized by chlorination and ozone, and most Chinese water plants are chlorinated. In order to prevent secondary pollution of tap water when passing through the pipeline, it is necessary to increase the amount of chlorine before the water leaves the factory. The dosage depends on the faucet water. The drinking water standard stipulates that the chlorine content in the faucet water is ≥0.05.
So what harm does chlorine in tap water have to the human body?
1. What is the effect of water containing residual chlorine on washing vegetables, fruits, grains, etc.:
Chlorine will destroy vegetables, fruits, vitamins, minerals and other nutrients, which seriously affect the body's absorption of nutrients.
2. What are the hazards of bathing with water containing residual chlorine for a long time:
Bathing with water containing residual chlorine, 40% of the total chlorine in the bathroom is inhaled through the respiratory tract. 30% is absorbed by the skin. It is usually 6 to 8 times as much as chlorine in the body. It is itchy and light. Carcinogenicity increased by 30%.
3. The tapping of tap water is even more harmful:
The organic humus in the water after the tap water is boiled produces carcinogens such as chloroform. Trichloromethane will increase by 3 to 4 times than tap water. If residual chlorine cannot be removed, the daily consumption of coffee, tea, and soup will increase the body's carcinogen by 3 to 4 times.
4. What diseases can be caused by long-term consumption of water containing residual chlorine:
Heart disease, coronary atherosclerosis, anemia, bladder cancer, liver cancer, rectal cancer, high blood pressure and allergies.
Do you know these water purifier sales lies?
How do you judge the chlorine in the tap water? We can judge the residual chlorine by "drinking" or "smelling".
Boiling water can solve most of the residual chlorine; if the "bleaching powder" of boiled water is still very strong, it can be treated by a water purifier.
Therefore, the first use of the water purifier is to completely remove the residual chlorine in the water, while a good water purifier can also remove impurities, bacteria, heavy metals, sediment, and residual pesticides in the water. If you have a water purifier sales, you should pay attention to the following.
Lie one: water after treatment of water purifier can cure
Many water purification products in the promotion of the product is too magical, in addition to various health effects, but also treatment of high blood pressure, diabetes, liver disease, gastrointestinal disease and so on.
The most common product is a product with a weak alkaline water health concept, claiming to drink alkaline water to change the body's pH. The pH in the stomach is about 2, what can you change if your weak alkaline water is drunk?
In fact, the body's acid-base balance is stable, and the external acid or alkali cannot change the body's pH. Moreover, the PH value of various parts of the human body is different. Which part of the body has you changed the PH value?!
There are also waters such as small molecule water, magnetized water, activated water, and what water will be added in the future. It is also a trick.
To be precise, the role of water in the body is to form a cell medium, transport nutrients, regulate body temperature, and moisturize.
Therefore, as long as the water is pure, it will not cause harm to the human body, it is safe, and it will not have any healing effect.
Lie 2: Drinking pure water to get rickets
Due to the low cost (no need to use a higher cost reverse osmosis membrane) or the promotion of steamed bread, unscrupulous manufacturers speculate on the concept of mineral water, the water of the reverse osmosis water purifier is not nutritious, claiming that drinking pure water will get rickets. In fact, the main role of water in the human body is to promote the body's metabolism, but not to provide nutrition to the human body. Mineral intake is mainly based on diet.
The drinking water standards in many countries in the world are based on pure water. Our country also has the standard of drinking pure water formulated by the state. It has never been heard of cases of rickets caused by drinking pure water. The case has proved that there is no such thing).
Therefore, it is not wise to remove so-called mineral water without removing other contaminants from the water.
Lie 3: We are an international brand with N years of history
The water purifier industry is a technology industry with a high threshold. It is really difficult for unprofessional manufacturers to really enter the market.
Many foreign brands have come to sell water purifiers in China. In fact, these foreign brands have never produced water purifiers (the history of non-production water purification equipment). They just look for some factories in China to carry out OEM work, and there is no guarantee of quality.
Some foreign brands of water purifiers do not understand the serious situation of water pollution in China. They use some equipment without reverse osmosis membranes to pretend to be high-tech products, which cannot deal with heavy metal ions, pesticides, hormones and other pollution in water.
What's more, many seemingly foreign famous brands, the name is also foreign, in fact, domestic companies are registered abroad, completely naked to deceive consumers.
In these cases, consumers only need to check the government health department approval documents and business licenses are basically clear.
Lie 4: Products can filter harmful heavy metals and retain useful minerals
Regardless of which filter membrane filters out objects larger than its own pore size, there is no automatic analysis of the composition of the filter material and its function. The technique of filtering only harmful substances to retain beneficial substances does not exist.
The nanofiltration membrane has a pore size of 0.001 μm, and it is impossible to filter a substance having a smaller pore diameter than itself. Therefore, it is impossible for the nanofiltration membrane to filter heavy metal ions having a smaller ion diameter. For example, the divalent lead ion has a diameter of 0.000155 micrometers and the divalent mercury ion has a diameter of 0.000204 micrometers.
However, the RO reverse osmosis membrane with a pore diameter of only 0.0001 μm has a much smaller diameter than the metal ion, and can completely filter these heavy metal ions (including minerals), leaving only water molecules.
Lie 5: The wastewater ratio is very small, it is the best reverse osmosis membrane
Although the quality of the reverse osmosis membrane wastewater is smaller, the positive correlation with the wastewater ratio is actually the severity of the water pollution.
Therefore, the use of wastewater is small to demonstrate that the quality of the reverse osmosis membrane is not very rigorous. Conventionally, the TDS in the water is higher, the wastewater is higher, and vice versa.
It should be pointed out that the above lies are often encountered, especially when the pyramid scheme products are used in the promotion.
