Carbon filtering Wikipedia

Mechanism. Carbon filtering works by adsorption, in which pollutants in the fluid to be treated are trapped inside the pore structure of a carbon substrate. The substrate is made of many carbon granules, each of which is itself highly porous.As a result, the substrate has a large surface area within which contaminants can be trapped.
