ACTIVATED CARBON FILTER

Forms of activated carbon

There are three main forms of activated carbon.

Granular Activated Carbon (GAC) - irregular shaped particles with sizes ranging from 0.2 to 5 mm. This type is used in both liquid and gas phase applications.

Basic Principle
 
Activated carbon filter works on the principle of adsorption.

Activated carbon is used for the removal of dissolved components from, freshwater waste water and marine systems. Activated carbon is effective against the following;

Adsorption is the process by which liquid or gaseous molecules are concentrated on a solid surface, in this case activated carbon. This is different from absorption, where molecules are taken up by a liquid or gas

Activated carbon is a crude form of graphite, the substance used for pencil leads. It differs from graphite by having a random imperfect structure which is highly porous over a broad range of pore sizes from visible cracks and crevices to molecular dimensions. The graphite structure gives the carbon it's very large surface area which allows the carbon to adsorb a wide range of compounds.
