Study on filter element grade of water purifier
2017-07-17
- General water purifier five filter, are PP meltblown filter PP熔喷滤芯+ activated carbon + PP melt blown filterPP熔喷滤芯+ RO membrane + post-activated carbon, roughly like this, but each is not the same.
First, PP meltblown filterPP熔喷滤芯. It is used as a filter element made of non-toxic and odorless polypropylene particles to remove impurities such as sediment, rust, colloid, eggs and so on, usually as the first filter of the water purifier. The replacement period is 2 to 4 month.
Second, the activated carbon filter. Divided into granular activated carbon filter and compressed activated carbon filter, sintered activated carbon. The innermost layer of the filter element is a polypropylene skeleton with a multi-layer polypropylene ultrafine fiber on the skeleton. The surface density is low and the replacement cycle is generally 6 to 8 months.
Third, Ro reverse osmosis membrane. Reverse osmosis membrane pore size of 0.0001 microns, under a certain pressure, water molecules can pass, and dissolved in the water salts, colloids, organic matter, heavy metals, bacteria, viruses and other substances will be trapped, the replacement cycle of 12 to 24 month.
Four, rear activated carbon filter (T33 filter). Material is also activated carbon, as the last level of filter, the role is to further remove the odor, residual chlorine and inhibit bacteria, to prevent the secondary pollution of purified water to improve the taste of purified water, so that clean water to drink better drink. The replacement cycle is also 6 to 8 months.
