What is the principle of water purifier? What s best?

There are many kinds of water purifiers, mainly physical filtration, first of all, PP cotton or quartz sand, (mainly filtering impurities such as sediment and rust), then activated carbon or compressed activated carbon (absorbing small molecules such as odor and colloids in water), and the last one is through reverse osmosis membrane and ultrafiltration membrane! High-grade water purifiers have several levels of filtration.

Hope, thank you!

For the health of your family, you should be cautious in the choice of water purifiers.

Most of the current water purifiers are reverse osmosis except for ultrafiltration, which cannot remove micro-pollutants such as pesticides and organic matter, but reverse osmosis is too clean.

"Pure water" is a popular concept in recent years. In many stores, when the shopping guide recommended the water purifier to consumers, he knocked on the hard scale on the kettle and said, "The ultimate solution to the scale problem is to install a water purifier, because it can not only remove the scale, but also improve the taste."

But is it really healthy to drink such water for a long time? The reporter consulted the relevant information with doubts and found that the World Health Organization pointed out as early as the World Water Congress in 2006 that water containing natural minerals and trace elements is good water; Dr. Martin Fox, a well-known American nutritionist, also said, "Pure water is not good for health. Distillers and reverse osmosis units are able to produce pure water that is softened and does not contain any beneficial minerals, and the effects of any harmful substances in this soft water are amplified and have a more negative effect on our health."

Therefore, the purer the water, the better, and the main task of the water purifier is to solve the problem of secondary pollution of tap water.

I chose Sanda's nano water filter to remove micro-pollutants and retain minerals. It's healthier that way!

Although the water purifier is a more commonly used household appliance, many people do not know much about its working principle. What is the water purification principle of household water purifiers? pchouse will take you to understand it.

The purification principle of the water purifier can be divided into two kinds, one is through the carbon adsorption capacity of activated carbon, so that many pollutants in the liquid enter the carbon pores, so as to lock the pollutants and make the water quality cleaner, and in the purification process, carbon can also form some oxygen-containing groups to make its chemical adsorption and catalytic oxidation and reduction performance stronger, so as to not only remove the pollution and hepei dye, but also remove some metal ions in the water. Of course, carbon adsorption purification is only the basic principle of water purifiers, and only a small range of water purification, such as purifying tap water, is only tried. If it is a more polluted water source, it will not be competent, and on the basis of the repeated decline in China's tap water quality standards, it is obvious that the purification of activated carbon can not be satisfied, so reverse osmosis purification technology has become the standard technology of water purifiers in the later stage.

Water is subjected to pressure and becomes an unstable membrane, and this membrane only allows pure water to pass through, and contaminants are removed, which can be achieved quickly through reverse osmosis, which was originally used to provide drinking water filtration for space station astronauts, and is now used in water purifiers.
