What is the reason why the activated carbon in the water purifier needs to be replaced regularly?

We all know that activated carbon is the more common filter element material in water purifier, filter element is the essence of all water purifiers, and because activated carbon is physical adsorption, no pollution, no side effects, and low price, so activated carbon is a more common filter element material in water purifier. So the activated carbon in the water purifier can be used for a long time, why should be replaced regularly?activated carbon sale

Because activated carbon is generally used as raw materials, such as fruit shells, branches and so on, in the case of air insulation high temperature heating, and constantly into water vapor, remove fruit shells, branches and other wood gas decomposed by heat, wood tar and other substances, its main component is carbon, so it looks black.

The activated carbon is filled with small pores inside and outside, so its surface area is particularly large. By calculation, the surface area of 1 gram activated carbon can reach 500-1000 square meters. This makes activated carbon have a strong adsorption ability, people can use it to adsorb harmful substances in water or air to purify water or air.

But activated carbon in the water purifier mainly plays a role of filtration adsorption, if used for a certain time, activated carbon adsorption saturation, once "full ", will lose the function of purification, and over time, the adsorbed substances and activated carbon itself will retain some microorganisms and bacteria.

So the activated carbon in the water purifier or filter can not be used for many years. After using a certain time, it is best to replace activated carbon in water purifier or filter tank in time, to three months to half a year is appropriate, the longest generally do not exceed one year, we should consider the replacement of new activated carbon. Although activated carbon will not dissolve in water, even if some small particles floating in the water, drinking will not do harm to the body, but still pay attention to the cleaning of the water purifier.activated carbon pellets manufacturers
