The types of filter elements can be varied. In different occasions, the filter elements used in different working media are different. Just like the type of filter used in hydraulic oil systems, there are hydraulic oil filter, Hedeck filter, Dawn hydraulic oil filter and so on. Let's take a look at what the features of several different filter elements are.
Filter function:
Polypropylene melt blown filter: pre-treats the incoming tap water, filters out sediment, suspended solids, colloids, impurities, etc. in the water, and has large filtration area and large amount of dirt, good filtering effect and long service life. It is recommended to replace it from June to September.
Granular activated carbon filter: adsorption of substances in the water, such as color, odor, halogenated hydrocarbons and organic substances, to ensure that the water entering the hollow fiber membrane meets the water inlet requirements of the membrane, effectively extending the life of the fiber ultrafiltration membrane filter. It is recommended to replace the normal use for 6-12 months.
Compressed activated carbon filter: It can adsorb heavy metal ions and further adsorb the various organic substances leaked before the second stage, protect the ultrafiltration membrane and prolong its service life. It is recommended to replace the normal use for 6-12 months.
Reverse osmosis RO membrane filter: The filter pore size can reach 0.0001 micron, which can completely filter out organic matter, heavy metal ions, bacteria, viruses, heat sources and other impurities in the water, and discharge the above harmful substances into the water purifier through the sewage system in time. It is recommended to replace it in 2 years - 3 years.
Rear composite filter: more completely absorb the heterochromatic, odor, residual chlorine and antibacterial in the purified water, prevent secondary pollution of purified water, make the drinking water more sanitary and safer, adjust the taste of water, and ensure the water is delicious and delicious. It is recommended to replace the normal use for 6-12 months.
Ion exchange resin: (softening filter) uses the principle of ion exchange to remove heavy metal ions such as calcium and magnesium to achieve the effect of softening water, and also remove some heavy metals to improve the taste. In general, the recycled resin cycle is 7-8 years.
Hollow fiber ultrafiltration membrane: The filtration precision is 0.01 micron, which removes impurities of bacteria, viruses, macromolecular organic matter, colloids and the like larger than 0.01 micron. It is recommended to replace it in 2-3 years.
Hydrophilic membrane: Deeper removal of bacteria, colloids, viruses, organic matter and other harmful substances in water. Recommended for 2-3 years replacement
