What is a water purifier?

1, classification of water purifier

There are many kinds of water purifiers, which are divided into coarse filtration and ultrafiltration according to the number of filter elements used. Generally, water treatment materials such as PP fiber cotton, coconut shell activated carbon, American KDF, ion exchange resin, tourmaline ore, medical stone, nano-ultrafiltration membrane, etc. are used, and there are one to nine filter elements and water purifiers.

2. Functions and disadvantages of the water purifier;

According to the different filter elements, the coarse filter water purifier can filter out impurities, rust, some bacteria, viruses, colloids and so on. In tap water, but it has little effect on heavy metals and water alkali. For the ultrafiltration water purifier above grade 5, the American KDF filter element and ion exchange resin filter element are added to effectively remove heavy metals and water alkali, and the activation and mineralization filter element is added above grade 7, which can not only achieve the purpose of direct drinking for users, but also achieve the purpose of health care.

3. Advantages of water purifier:

Safe drinking, retaining most minerals in raw water, softening water quality, no waste water and no electricity.

4. Features of the water purifier:

There is no motor, no power supply, and filtration is driven by water pressure. There is no water storage tank, and the nine-stage filtration is better.

What is a pure water machine?

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.
