Calgon Carbon is a supplier of more than 100 types of granular, powdered and pelletized activated carbons as well as activated carbon cloth, used by thousands of customers around the world for water treatment, liquid- and vapor-phase purification, and other applications.
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.
During adsorption, liquids or gases pass through a bed or layer of highly porous material called the adsorbent. The compound or compounds to be removed, termed the adsorbate(s), diffuse to the surface of the adsorbent and are retained because of weak attractive forces. Adsorption occurs on the internal surfaces of the materials.
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 furnaces. This heating process is known as activation, and develops the pore structure of the carbon. Through adjustments in the activation process, pores of the required size for a particular purification application are developed.
Activated carbon products are the very backbone of Calgon Carbon. Since 1942, we have been the industry innovators, pioneering new products and applications by developing superior-performing activated carbon products.
