Water purifier with activated carbon in the carborod filtfun
water purifier with activated carbon in the carbon rod filter function, what is it? Take a look at Xiaobian introduce it.
at the time of purchase pure water, the sales staff will inform consumers of this water purifier has five filtration system to purify the water more pure. Five filtration system: pp cotton, granular activated carbon filter, activated carbon filter block, reverse osmosis filtration, the carbon filter. 2020-06-04, we talk about water purifier with activated carbon carbon rod in the function of the filter.
Pure water has a post-carbon filter system capable of purifying water depth, the raw water through the water purifier filter layers, come when post carbon filter, adsorption can be more thoroughly in clean water color, smell, taste pure water adjusted while suppressing bacteria reproduction of purified water, to ensure clean sweet taste.
1. A powder activated carbon (the PAC)
is actually a particle size of powdered activated carbon finer particles of activated carbon. Because of small particles, large surface area, it is better than the commonly adsorption of granular activated carbon
2. Granular activated carbon (the GAC)
which is commonly used in the activated carbon in water purification. The smaller the particles, the better the adsorption capacity, but the water resistance (pressure drop), the more prone to leakage when char, so water purifier manufacturer should select the appropriate particle size. In a large water treatment plant, often used 10-24 mesh (0.8-2.0 mm diameter), since the small household water purifier carbon short column height, Fast Flow, short contact time with the activated carbon water, suggested the use of 16-32 mesh (diameter 0.6-1.3mm). .
3 of activated carbon fiber felt (the ACF)
according to different raw materials, which have two kinds: one is viscose filament as raw material, processed into cloth, carbonization, activation , in high temperature; the other is a group Qing polypropylene fiber as raw material, processed into a mat, pre-oxidation, carbonization, activation, high temperature. Activated Carbon Fiber faster and properties with good reproducibility, desorption speed, can be reused. The disadvantage is more expensive, but also easy to breed bacteria.
4. Sintered activated carbon filter (CTO)
The sintered activated carbon filter (CTO), also known as carbon rod filter, compressed activated carbon filter. Granular activated carbon is added to the binder(E.g. PE resin) heated sintering extruded, the outer layer tends to further filter the white polypropylene (PP) nonwoven fabric. Sintered activated carbon filter both adsorption and filtration (average pore diameter 3-20um) two functions, but its filtering function is lower than PP meltblown filter, activated carbon filter particles adsorb function below.
through these presentations, I believe you know the function of knowledge in water purifier with activated carbon filter carbon rod of the bar. You also promise that you will ask: home water purifier it is necessary to install small advice you should not blindly, need to decide according to their own home water quality, water quality standard is actually based on what family does not need to drink small knowledge base?.
