Granular Activated Carbon

Calgon Carbon created the first granular activated carbons (GAC) from bituminous coal in the 1940s and has staked a position of global industry leadership ever since.

Today, more than 70 years after its founding, Calgon Carbon remains on the cutting edge of innovation, offering an exceptional range of GAC and reactivated carbon formulations engineered specifically for the purification of water, air, liquid and gases to sustain human life and facilitate numerous industrial processes.

Features & Benefits:

The adsorptive capacity of granular activated carbon (GAC) makes it ideal for removing a variety of contaminants from water, air, liquids and gases. GAC is also an environmentally responsible product that can be reactivated through thermal oxidation and used multiple times for the same application.

As the world’s largest manufacturer of GAC, Calgon Carbon backs its products with comprehensive analytical support, including feasibility studies and cost evaluations, together with complete system design, service, and troubleshooting.

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.
