How does activated carbon for water filters work?

The most common application for activated carbon is water treatment, usually after disinfection, where chemical reactions can occur. In addition, water is generally disinfected before it passes through activated carbon adsorbents to prevent bacterial growth. Activated carbon serves as a granular medium to remove chlorine and organic elements that are considered undesirable in drinking water.

But in many cases, when the chlorine is eliminated in the first centimeters of the carbon bed, it is unprotected from bactericides and by retaining organic matter it can be a fertile bed for bacteria, so it is highly recommended to use cartridges with bacteriostatic activated carbon impregnated with silver to prevent the development of macroorganisms in the cartridge.
