The composition and principle of RO water purifier.


The water purifier is also called water purifier, which can be divided into RO reverse osmosis water purifier, ultrafiltration membrane purifier, energy purifier and ceramic water purifier.

Today we will introduce the RO water purifier.


The general reverse osmosis water purifier of RO water purifier is filtered in the form of 5-stage filtration.

The diagram below:

Level 1 filtration: currently, the water purifier in the market generally adopts the PP cotton of 5 mu m as the filter core material, which is used to remove impurities such as rust and sand grains.


Secondary filtration: using granular activated carbon as the filter material, can effectively remove the odor and improve the purity of water.

The removal rate of all kinds of impurities such as chlorine, phenol, arsenic, lead and pesticide in water is also high.


Three-stage filtration: PP cotton with 1 mu m is used as the filter core material, and some manufacturers use compressed activated carbon as the filter core material.

Enhance the effect of primary and secondary filters.


Four-stage filtration: RO reverse osmosis membrane, made of specific polymer materials, with selective properties of films.

It can selectively penetrate water and certain components in aqueous solution under pressure, so as to achieve purification or enrichment and separation.

Because the membrane pore diameter of reverse osmosis membrane is very small, it can effectively remove dissolved salts, colloid, microlife and organic matter in water.

It is the main component of the reverse osmosis water purifier. Its performance index directly determines the effect of water purifier.


Five-stage filtration: post-activated carbon, the main effect is to improve the taste of water.



RO water purifier water purification principle simply its technical principle mainly use the pressure gauge for dynamic membrane filtration technology, the technology originated in the 1960 s, at first it is mainly used for space research, with the continuous development of technology updates, slowly into the home, the more widely application at present.


RO reverse osmosis membrane pore size is small to nanometer scale (1 nanometer =10-9 m). It is one millionth of the hair, and can not be seen by the naked eye, and the bacteria and virus are 5000 times.

Under certain pressure, the H2O molecules can pass RO membrane, and the source of the inorganic salt in the water, heavy metal ions, organic matter, colloid, bacteria, viruses and other impurities through the RO membrane, which can be through the water and can't distinguish strictly through the enrichment of water, so as to achieve the aim of water purification.

The following diagram is the schematic diagram of the RO film:



RO reverse osmosis water purification mechanism of pure water relative to the bottled water is more fresh, more health, safer, it for water purification brand has a very wide range of USES: to have drink, also can drink, boil in this respect, the most outstanding characteristic is the kettle or electric thermos would never "scale;

Pure water for cooking, more sanitary, more delicious;

Use pure water to wash bath, can remove impurities on the skin, moist skin, have the effect of natural beauty;

Water purifier, water purifier can provide water to humidifier, steam irons, beauty equipment and other small household appliances, and will never show the disgusting scale.

The water from the water purification equipment made from this technology is used with the ice making machine, and the ice crystal is crystal clear without any peculiar smell.



Is it harmful to the human body to drink water from RO reverse osmosis water purifier?

At present, the society has a saying: "RO reverse osmosis water purifier filter out all the water on the human body useful minerals, made of pure water has no minerals, unfavorable drink more, get rickets".


According to the Chinese center for disease control environment and health related product safety researchers learn the ritual of hubei, it seems there is something, but careful analysis, you will find that there is no scientific basis.

The function of water in human body is: 1 food digestion, 2 nutrition transportation, 3 blood circulation, 4 waste excretion, 5 body temperature regulation.

We've never heard of a person who has a lack of nutrition and vitamins, and doctors ask patients to drink water to supplement their nutrition.


Nutrients and minerals that the body extracts in water account for only 1% of the total, and 99% of the nutrients and minerals are obtained from grains, fruits and vegetables, and chicken eggs, rather than from the water.

For example, if you want to get enough molybdenum from water, you can drink 160 tons of water every day, but you can meet the demand for molybdenum by eating a potato melon and a handful of melon seeds.

Again, for example, quantity is equal to one thousand two hundred glasses of water a glass of milk, a pound of beef iron content is equal to eight thousand three hundred cups of water, a glass of orange juice vitamin content is equal to three thousand two hundred cups of water content;

So the person lacks nutrition, can only through food supplement, cannot rely on water.

In addition, organic minerals in the water are not directly absorbed by the human body. Only through the absorption of animals and plants can the human body absorb the edible parts of these animals or plants so that the body can absorb them.


We have heard in life that there is a lack of a certain vitamin to be supplemented by drinking water!


It is not wise to clean up a hundred times better than the pollution, for a little bit of nutrition, to drink dirty water.
