1, PP filter water purifier: inside the various PP filter single cylinder water purifier, generally low price, but the filter is easy to clog, need to be replaced often, and the filtration precision is not high, only for the initial filtration of water.
2, activated carbon filter: can eliminate the color and odor of the water, but can not remove bacteria and other harmful substances in the water, sediment, rust removal effect is also very poor.
3, reverse osmosis water purifier: completely remove beneficial and harmful substances in water, the output is pure water. Need to add pressure and electricity, low water utilization (more wastewater, less pure water, generally to waste about 50% of the tap water). Purification cost is high, the flow rate is small, only to solve the problem of drinking water.
4, water softener: the general use of regenerative sodium resin replacement of calcium and magnesium ions in the water, only soften, reduce the hardness of the water, can not be purified, can not remove a variety of harmful pollutants in the water.
5, barrel water purifier: installed in the water dispenser barrel water purifier, generally using activated carbon, ceramics, mineralized balls and other filtration materials, filtration accuracy is not high, is completely retained filtration, cleaning is inconvenient, easy to form a secondary pollution, small amount of water, just positioning to solve the problem of drinking water, but in fact, clear filtration technology is not afraid to drink the people.
6, ultrafiltration water purifier: can effectively remove sediment, rust, suspended solids, colloids, bacteria, macromolecules, organic matter and other harmful substances in the water, and retain the beneficial minerals trace elements. Long service life of the cartridge, large water output, without electricity, pressurization, low purification costs, high water utilization rate, suitable for a large number of living water purification.
7, mixed media filter: according to the functional characteristics of different filtration materials, the use of a variety of technical combinations to achieve a wider range of water quality treatment, comprehensive and effective removal of various harmful substances in the water. For example, Jinliyuan kitchen water purifier adopts ultrafiltration as the core component and combines with high-performance KDF, which can not only effectively remove sediment, rust, suspended solids, colloids, bacteria, macromolecular organics, etc., but also inhibit bacterial growth in the water and remove heavy metals through KDF, so that the filtered water is safer and healthier; the water utilization rate of up to 95% or more, and the large water production can easily meet the purification needs of household kitchen water. family kitchen water purification needs.
8, functional water purifiers: the market there are a lot of claims to have health care functions of some water machine, such as ionized water machine, spectrum water machine, and magnetization, mineralization, activation of water purifiers, etc., but in fact, these functional water machine does not have the advertised functions, and because these water purifiers do not have a real filtration function, can not solve the actual problem of water pollution. The State Ministry of Health also issued a notice in July 2005, any water-related products shall not claim to have health care functions, all over the world are prohibited from selling water ionizers and other functional water machine. Most of the water purifiers on the market today are aimed at solving the problem of drinking water, claiming benefits compared to bottled water, and competing with bottled water.
From the filtration structure, the water purifier is divided into two ways
One is the complete retention of the filtration method, the structure of a water inlet, a water outlet, the retention of dirt can not be discharged in a timely manner, easy to block, easy to cause secondary pollution, the use of a short life.
The other is with a rinse port,, a water inlet, a purified water outlet, and a rinse port, can realize the automatic rinsing of the water purifier, to prevent clogging, attenuation, to prevent secondary pollution, the service life is also longer.
