Compared with bottled water, purified water produced by RO reverse osmosis is fresher, more hygienic and safer. It has a wide range of uses: it can be drunk raw or boiled. The most prominent feature in this respect is that the kettle or electric thermos will never scale again. Pure water for cooking is more hygienic and delicious;
Bathing with pure water can remove impurities from the skin, moisturize the skin and play a natural beauty effect; It can provide water for small household appliances such as humidifier, steam iron and beauty instrument. And there will never be an annoying scale; When used together with an ice maker, the ice cubes made are crystal clear without any peculiar smell.
1, the working principle of water purifier:
The technical core of water purifier is reverse osmosis membrane. Its working principle is to exert a certain pressure on water, so that water molecules and ionic substances pass through a reverse osmosis membrane, while most of the organic substances, bacteria and viruses dissolved in water cannot pass through the reverse osmosis membrane, thus strictly separating the permeated pure water from the impermeable concentrated water. The pore size on the reverse osmosis membrane is only 0.000 1-0.00 1 micron, which is equivalent to one.
2, the category of pure water machine:
According to the usage, it can be divided into manual (or economical) and automatic. The difference is only in the backwashing of the water purifier. The economical water purifier uses a manual backwashing valve.
4, the characteristics of pure water machine:
There is a booster pump, a power supply and a water storage tank, which are generally five-stage filtration. The first stage is filter element, the second and third stages are activated carbon, the fourth stage is RO reverse osmosis membrane for aerospace technology (this is the core), and the fifth stage is refined activated carbon, which is mainly used to improve the taste. In the fifth stage, a medical stone filter element can also be placed to become a mineral drinking water purifier.
5, the function of pure water machine:
It can not only drive away impurities, rust, sediment, colloid, bacteria and viruses, but also drive away radioactive particles, organic substances, fluorescent substances and pesticides harmful to human body. It can be said that there are substances besides water molecules, which are very clean water.
6. Disadvantages of water purifier:
There is a booster pump, a power supply and a water storage tank. The water purifier will produce wastewater in the process of making water. The pore size of RO reverse osmosis membrane of water purifier is very small, so water must be pumped by pressure. Impurities that cannot pass through RO membrane are poked out, which will produce a lot of wastewater. Most of the purified water produced is weakly acidic water, which is not suitable for long-term drinking at home.
