What is Activated Carbon?

Activated carbon is a porous material that removes organic compounds from liquids and gases by a process known as “adsorption.” In adsorption, organic molecules contained in a liquid or gas are attracted and bound to the surface of the pores of the activated carbon as the liquid or gas is passed through.

Adsorption occurs on the internal surface of activated carbon, termed the adsorbent. During adsorption, liquids or gases pass through the highly porous structure of the activated carbon. The compound(s) to be removed, termed the adsorbate(s), diffuses to the surface of the adsorbent and is retained because of attractive forces.

The primary raw material used in the production of our activated carbons is bituminous coal that is crushed, sized and processed in low temperature bakers followed by high-temperature activation furnaces. Activation develops the pore structure of the carbon. Through adjustments in the activation process, differentiated pores for a particular purification application are developed.

What is Carbon Reactivation?

Calgon Carbon Reactivation Services include the reactivation of spent carbon on a custom basis or a pool basis. Customers in the municipal drinking water, food application or industrial sectors can have their spent carbon reactivated with the resultant product being returned to them (Custom Reactivation). Alternatively, customers may put their spent carbon into a generic pool for reactivation, making this a cost-effective product alternative when getting your own material returned is not required or a cost-effective recycling option as opposed to disposal when virgin material is required.

Calgon Carbon’s custom municipal reactivation (CMR) products, custom food grade reactivation (CFR) products and custom industrial reactivation (CIR) products are put through the same quality testing system as the original virgin materials.
