Is there a need to install a water purifier? Choose your own!
Open the faucet and look forward to receiving a cup of clean tap water. I didn’t expect it to be yellow, red, or blue. I hate to get enough rainbow-colored polluted water. Of course, this is not the most terrible. The most fear is that tap water looks clean, but it is harmful. For the masses who do not know the truth, the final result is often that the water plant is lying in silence, but the culprit has been “on the road.” There is a saying that “the secondary pollution of tap water is risky, and it is necessary to be cautious when drinking directly.” Is it so difficult to reduce the risk and drink the water with peace of mind?
Now more and more friends know about the water purification system. Is there any need to install a water purifier, score the water quality, and score the person (the subjective method).
The following is discussed in three different situations:
1, boiled water still tastes bad;
2. The water may contain heavy metals;
3. The water quality is clear and the taste is normal.
Drinking water still tastes bad
There is still bleaching water after the tap water in the house is boiled. It feels a bit awkward when drinking, and the kettle is easy to scale.
The taste of bleach is because there is residual chlorine in the water. Chlorine is added to the tap water for sterilization. After the tap water is discharged from the water plant, the secondary pollution is reduced in the long pipeline transportation to keep it fresh. Therefore, tap water must contain residual chlorine, but it is a matter of content. Only when the content is high can people feel it. Chlorine is a very water-soluble gas that evaporates when boiling. Chlorine also combines with organic matter in water to form carcinogens of trihalomethanes. Fortunately, trihalomethanes are also volatile liquids that can be removed by boiling.
The scale is high and the water feels awkward because of the high water hardness. However, the high water hardness is easy to get the disease of stone disease. At present, there is no scientific basis. The hardness of water can be reflected from the TDS value. The TDS value is the total amount of soluble solids contained in 1L of water. It can be measured by TDS (the millet has a 39 yuan). The water quality in the southern region is generally soft, and the northern region is hard. The domestic TDS is already very high at 600mg/L, but it is still far below the national drinking water standard of 1000mg/L.
In summary, the correct method of residual chlorine and high hardness of tap water to boil and drink, will not cause harm to the human body, but will lead to poor taste, affecting people’s desire to drink water, this situation is still necessary to purify, let The taste of the water is better.
Water may contain heavy metals
If you are located in an area with serious industrial pollution and worry about heavy metals in the water, the best way is to install the RO reverse osmosis water purifier with the highest filtration accuracy.
The structure of the RO reverse osmosis water purifier is very similar to that of the ultrafiltration water purifier. The biggest difference is that the RO membrane is one of the RO membranes, which is smaller than the pore size of the ultrafiltration membrane and can filter out heavy metals in the water. Calcium, magnesium and other ions theoretically only allow water molecules to pass, and the filtered water is pure (net) water, which is the highest filtration precision in current water purifiers.
Clear water and normal taste
If the tap water in the home looks pure and transparent, and the water after boiling is normal, then it is lucky to encounter tap water with good water quality.
In the past two years, the water treatment capacity of the waterworks has been continuously improved, and only the national drinking water standards can be allowed to be transported.
Therefore, the state still has certain norms and requirements for the quality of tap water, and it is not so terrible. If the mentality is good, it will be OK to boil it directly. After all, boiling water can remove most of the residual chlorine, trihalomethane, and scale, and the high temperature can also be sterilized. But to achieve this effect, boiling water is also very particular.
1. After the water is boiled, open the lid and continue to boil for about 3 minutes to allow the residual chlorine and trihalomethane to evaporate more thoroughly;
2, the water that has just been boiled should not be immediately (not because of the hot mouth), the scale has not settled, and the residual chlorine and chloroform have not completely evaporated;
3. After a period of precipitation, the water near the scale of the bottom of the pot is drained and try not to drink.
If you always doubt the quality of tap water and always worry about any invisible harmful substances, the most reliable treatment is the same as the heavy metal above. It is safer to install RO reverse osmosis.
With the improvement of people’s living standards, many people have bought water purifiers. Reverse osmosis water purifier, ultrafiltration water purifier, kitchen water purifier, whole house water purifier… different names, different uses. In short, a water purifier can be used as long as it can be used.
In summary, the insider’s suggestion is to decide whether to install or not according to the living environment. If your city does not pollute the green mountains and green waters, you can do it without it; but if your city has industrial pollution, the factory exhausts the sewage. More, then install! But be sure to pay attention to the good brand that has a good reputation. The filter has to be changed frequently, don’t save money and be lazy!
