Odours from organic compounds found in general air pollution, wastewater, soil emissions, and building emissions can pose serious health risks if they are not controlled. The odour causing molecules can be removed from the air permanently through the use of activated carbon.

Environmental awareness and concern for satisfactory working conditions has focused attention on the prevention of organic odours. Noxious compounds such as hydrogen sulfide (H2S, hydrogen sulphide) are readily trapped through adsorption followed by chemisorption or catalytic conversion, while other organic compounds and mercaptans can be adsorbed by activated carbon.

Activated carbon

Calgon Carbon and Chemviron have over 70 years experience in manufacturing of the highest quality activated carbons for use in gas treatment and emissions control applications. Activated carbon products are available in a range of granular and pelleted particle sizes to fit a variety of applications.

Reactivation services

Chemviron offers safe and economical spent carbon handling and thermal reactivation (total destruction of the adsorbed organics), in conjunction with fresh carbon supply and provides personnel and equipment to perform the carbon exchange on a turnkey basis.


Chemviron can bundle the performance advantages of vapor phase activated carbon with adsorption equipment (service or purchase) and related services, to provide a full turnkey solution.
