By filter element composition structure is divided into RO reverse osmosis water purifier and ultrafiltration membrane water purifier, energy water purifier, ceramic water purifier and so on.
RO reverse osmosis water purifier is equipped with a standard 5-stage filtration, namely:
The first level of PP cotton, primary filtration, mainly filter sand, rust, such as large particles visible to the naked eye
The second level of granular charcoal, organic matter in the water and the inorganic colloids have a strong retention effect, with deodorization, odor, odor, residual chlorine, decoloration and other effects
The third level of compressed carbon, odor, residual chlorine, aromatic, COD organic matter has a good removal
The fourth level of RO reverse osmosis membrane, RO reverse osmosis membrane pore size of 0.0001 microns (0.1 nanometers), a bacterium to shrink 4,000 times, infectious viruses to shrink more than 200 times in order to pass through, and therefore can be
effective removal of bacteria, viruses, heavy metal ions, pesticide residues in water.
The fifth level for the rear of the activated carbon (also known as small T33) 5; the use of activated carbon adsorption principle, can effectively remove residual chlorine in the water, toxic and harmful substances, improve water quality and taste
Ultra-filtration water purifiers are ultra-filtration membranes as the main, other cartridges, such as activated carbon (excluding energy cartridges) as a complementary ultra-filtration water purifiers are divided into vertical and horizontal two types of water purifiers in accordance with the installation mode.
Vertical ultrafiltration water purifier is composed of PP cotton, granular activated carbon, compressed activated carbon, external pressure ultrafiltration membrane, T33;
Horizontal ultrafiltration water purifier "commonly known as pipeline ultrafiltration machine" is composed of stainless steel shell and internal pressure ultrafiltration membrane, KDF.
Ultra-filtration water purifier has 3 to 12 levels of cartridge filtration, largely PP cotton cartridge, carbon cartridge, ultrafiltration membrane, and some what alkaline alkaline dechlorination and other functional cartridges,
Second, the household water purifier priced at 500-8000 ranging from the ultra-filtration machine is generally the lowest 5, up to 13, RO water purifier comes standard is a 5-stage filtration, the price of different brands! The price of different brands varies greatly, and should be verified by many parties before purchasing.
Three, the market is popular with the big brands have the United States, Hamilton, Qinyuan, etc., to buy water purifiers should pay attention to the following points:
First, look at the local water quality, how to use the RO machine or ultra-filtration machine.
Second, look at the level of service and attitude of the dealer,
Third, look at the price level they accept,
Fourth, look at the after-sales service,
Fifth, look at the appearance of the product, whether or not they prefer,
Sixth, look at the function of the product, whether or not it is suitable for the use of the time to use,
Seventh, look at the amount of water per day, 75G or 50G
--------- listen and watch more, first understand, and then enter the purchase!
Fourth, we recommend the use of Hamilton water purifier|high-end quality water purification experts cost-effective, good service, water quality is guaranteed.
