Activated carbon is a kind of water purification material that is used more. The new activated carbon can adsorb most organic matter in water. As the organic matter adsorbed on the surface of the micropores gradually increases, some of them will fall back into the water, which is called the desorption process.

The adsorption and desorption of activated carbon are carried out at the same time. After a period of use, the purification effect of activated carbon is lower than at the beginning, but the amount of adsorption is much larger than the amount of desorption, and the water purifier still has a good purification effect.activated carbon manufacturer south africa When activated carbon adsorbs more and more organic matter, the amount of desorption will also increase. When the adsorption and desorption are basically equal, it is equivalent to the activated carbon no longer has the adsorption effect, which is the end of the life of the activated carbon. All water treatment media have a service life!

We should try to choose a filter medium with a longer life. Theoretically speaking, try to choose a water treatment medium that can remove harmful substances such as residual chlorine and heavy metals in the water through reaction, and can also bring substances that are beneficial to organisms to the water.

When the water purification material treatment work runs to 75% of its life, its ability to remove toxic and harmful chemicals in the water is greatly reduced. At this time, although no obvious signs of deterioration of the purified water quality were found, as the organic matter adsorbed on the surface of the micropores gradually increased, some of them would fall into the water again. At this time, the inherent quality of the water has gradually deteriorated, and the filter material should be replaced.

Filter materials such as activated carbon, in fact, all filter materials are included. After the service life is reached, they no longer have adsorption capacity, and all their surfaces are covered with adsorbed organic matter, which becomes the culture medium for various microorganisms, leading to The growth of bacteria not only can not purify the water quality, but will pollute the water quality. The ceramic ring we usually use also exists.www.granular-activated-ca...
