In recent years, urban pipeline pollution and the pollution of major lakes has accelerated the development of water purifiers, and now water purifiers have gradually entered thousands of households, guarding the drinking water health of many families. For the water purifier, the core component is its cartridge, used the water purifier know that there are many water purifier cartridge, especially the activated carbon cartridge inside, more kinds. So what role can different kinds of activated carbon cartridge play in the water purifier?

　　First of all, understand what is activated carbon. Activated carbon is a special treatment of carbon, with countless tiny pores and a huge surface area. Activated carbon has a strong physical adsorption and chemical adsorption function, which can effectively filter out harmful substances, while its huge area can adsorb harmful substances in the micro-pores of activated carbon, thus preventing harmful substances from being absorbed by the human body in the water.

　　Water purifier internal cartridge types generally have granular activated carbon cartridge, compressed activated carbon cartridge and post-silver-carrying activated carbon cartridge three. Among them, granular activated carbon using high-quality coconut shell activated carbon, can be adsorbed in the water color and odor, residual chlorine, halogenated hydrocarbons and organic substances and other harmful substances. The function of compressed activated carbon is similar to that of granular activated carbon, except that it plays a further role in filtration. The post-silver-carrying activated carbon cartridge can improve the taste of water, but also play a role in inhibiting the regeneration of bacteria.

　　The advantages of activated carbon cartridge.

　　1、no desorption, no secondary pollution

　　Many people worry that the water purifier they buy can not achieve the effect of water purification, but also cause secondary pollution. Many water purifiers use granular activated carbon cartridge, and granular activated carbon in the impact of water flow, may lead to the filtered water becomes black, requiring a long time to flush to normal use. The activated carbon rod cartridge will not, in addition to the first use will have some black water, after the use of the phenomenon of black water will not appear, not to mention the formation of secondary pollution because of adsorption.

　　2、Filtration without dead ends

　　Granular activated carbon cartridge and activated carbon rod cartridge has the advantage of a large surface area, can be in full contact with the water, filtering out the impurities in the water, leaving no dead ends.

　　3、Wide range of use

　　Granular activated carbon cartridge has a single role, less than the composite use of other filter media, while activated carbon powder can be mixed with a variety of multi-functional filter media powder processed into a rod-shaped functional cartridge, targeted to remove a variety of pollutants in the water.

　　The activated carbon cartridge in the water purifier plays a big role, we must not underestimate it! In addition, when replacing the cartridge, be sure to choose the regular water purifier brand cartridge for replacement, the filtration effect is guaranteed.
