What is activated carbon?

Activated carbon is a porous material that removes organic compounds from liquids and gases through a process called "adsorption". In adsorption, organic molecules contained in a liquid or gas are attracted and bound to the pore surface of the activated carbon as the liquid or gas passes through.

Adsorption occurs on the inner surface of the activated carbon, called the adsorbent. During the adsorption process, the liquid or gas passes through the highly porous structure of the activated carbon. The compounds to be removed, called adsorbates, diffuse onto the surface of the adsorbent and are retained due to the attractive force.

The main raw material used to produce our activated carbon is bituminous coal, which is crushed, graded and processed in low temperature roasters and high temperature activation ovens. Activation develops the pore structure of the carbon. By adjusting the activation process, different pores are developed for specific purification applications.

Application

The main applications are activated carbon for drinking water, wastewater, odor control, pollution control and various industrial and commercial manufacturing

Air Filtration
Air is vital to the survival of all living things. Activated carbon products filter and treat harmful and unwanted contaminants in the air and air stream.

Automobiles
Vehicles produce harmful fuel system emissions. Activated carbon products adsorb pollutants to produce clean air.

Food and Beverages
Nature produces delicious food and beverages. Activated carbon products improve color and flavor, eliminate odors and increase purity.

Gold Recovery
Gold is a precious commodity. Activated carbon products reduce the loss of gold during mining.

Pharmaceuticals
Pharmaceutical products help support healthy living. Activated carbon products help to manufacture certain compounds and drugs to improve purity, potency and stability.

Water purification
Water is vital to life. Activated carbon products condition, treat and purify water
