Classification of household water purifiers processing mode 【 3 m filter.

Household water purifier according to water quality treatment can be divided into the following categories:

1. Mineralization law

means on the basis of purification to add to the human body beneficial mineral water ( Such as calcium, zinc, strontium and other elements) Its purpose is mineral water, health care function into full play. Commercial water purifiers usually by medical stone is added in the water purifier to achieve the purpose of mineralization, but the artificial mineralization effect is still a controversial issue.

　　2. Activated carbon adsorption

is relatively common, multi-purpose nature, coal, nut shell ( Nuclear) Such as carbon by chemical method or physical activation method. It has a huge number of pores and specific surface area, thus has very strong adsorption capacity, effective adsorption of organic pollutants in the water. Moreover in the process of activation, non-crystalline area formed on the surface of the activated carbon filter some oxygen containing functional groups, these groups make activated carbon with chemical adsorption and catalytic oxidation, reduction performance, can effectively remove the water some metal ions.

　　3. Magnetization method

refers to the use of effects of magnetic field treated water, known as the magnetization of water treatment. Magnetization treatment is the process of water after the perpendicular to the direction of the magnetic field lines through the magnet, magnetization treatment process is completed. Magnetization of water treatment in our country, so far is still in the early stages of practice and research, not magnetizing water purifier foreign function request, because the magnetized water does not belong to the scope of water purification, but belong to medical problems.

　　4. Microfiltration and ultrafiltration method

micro filtration is made of cellulose or polymer microporous membrane filter, using the uniform aperture to intercept the particles in the water, colloid, bacteria, etc. , make the impassability membranes and be removed. The microporous membrane filtration technology is also called particle filter technology, can filter micron or nano-sized particles and bacteria.

　　5.

RO reverse osmosis RO reverse osmosis membrane water purification mechanism of pure water relative to the bottled water is more fresh, more health, more security, it has a very wide range of USES: to have drink, also can drink, boil in this outstanding characteristic is the kettle or electric thermos would never 'scale; Pure water for cooking, more health, more delicious.

　　6. Drinking after boiling method is to point to tap water to boil, which is an ancient method, widely used in the country. Boil water to kill bacteria, but for some chemicals and heavy metals, does not remove even if its content is very low, so is still not safe.

　　7. Compound

when a process is difficult to remove the water harmful material, using two or more than two kinds of process is complex. Such as activated carbon adsorption plus ultraviolet sterilization, activated carbon adsorption and reverse osmosis, activated carbon adsorption and microfiltration ( The ultrafiltration) , polypropylene superfine fiber plus activated carbon and microfiltration ( The ultrafiltration) And so on.

　　8. Softening method refers to the water hardness, Mainly refers to the water calcium and magnesium ions) To remove or reduce a certain amount of water. The water in the process of softening, just softening water quality, to improve water quality.
