Nowadays, in the various sales of water purifiers, we hear a lot about the secondary pollution of tap water. It is said that the secondary pollution of tap water requires the installation of a suitable water purifier, which can help intercept these pollution and reduce the impurities in the entrance. Because of these publicity, the sales of water purifiers are also increasing, so is there really secondary pollution of tap water, or is it a scam designed by merchants in order to stimulate sales?
It is said that there is secondary pollution in tap water, is it true?
Tap water in most areas is municipal tap water, which is disinfected to meet eligibility standards and transported to homes. Under normal circumstances, the tap water is qualified, no water purifier is needed, only boiling water, you can drink with confidence. But now we hear about some secondary pollution of tap water, and if these pollutions really exist, will it have an impact on us?
Sources of secondary pollution of tap water:
First, aging pipes. After some pipes are aged for a long time, they will pollute the tap water for a second time. In many first-tier cities, new pipes have long been replaced, not the pipes that are easy to age in the past, but in some areas, tap water has become less clean. Aging pipes contain all kinds of bacteria, sediment and other substances.
Second, unclean cisterns. There are reservoirs in the community, to help transport tap water to the home, some of the old community reservoirs accumulate day by day, it is easy to leave a lot of impurities and pollution in the water, regular cleaning is not clean, tap water will be relatively poor. In fact, every time we stop the water and come back to the water, the tap water is very turbid, that is, the water at the bottom of the reservoir, too dirty to use!
Third, the pipe ruptures and other substances enter. Water pipes because of various factors, there will be a case of pipe rupture, after the rupture, there will be other substances into the water pipe, with the water flow slowly into the home tap water, so some invisible pollution, there may be a lot of suspended solids inside.
Fourth, the pollution of high-rise water tanks will affect the water use of high-rise residents. We all know that the water quality of high-rise residents is not very good, because it is a secondary pressurized transportation, and the high-rise water tank has rarely paid attention to it in the past, and it contains dirt and grime, beyond your imagination. Some reporters have also specially investigated, and found that the problem of high-rise water tanks is very serious, not only the material is rusty, but also a lot of dirty substances have accumulated inside, which is visible to the naked eye.
Because I understand that the water quality in some areas is relatively poor, there will be a need for water purifiers. There will be a market if there is a need, not a water purifier first, and only then will the tap water be publicized as a secondary pollution.
Is the water purifier promotion a scam for the merchant, or is it really useful?
Because of the best-selling water purifier in recent years, some people question its role, thinking that the water purifier is not a scam, in fact, there is no effect? What exactly does a water purifier do?
The role of the water purifier is to filter the tap water, so that the water quality becomes better, for the tap water has secondary pollution, it can effectively intercept these dirty substances, so that the water quality is better. The role of the water purifier is for poor water quality, can have a very obvious effect, water quality taste better, and better filter element, found that the filter element is dirty!
Another function of the water purifier is to facilitate the need for drinking water. In order to improve the convenience of drinking water, some families choose bottled water or choose water purifiers. Although the price of the water purifier will be more expensive, the relative effect is good, and the use of more uses, practical!
There is no problem with the role and effect of the water purifier, but the quality of the product will be inferior and good or bad. When buying a water purifier, we have to avoid some pitfalls and choose the right product according to our needs.
