Gas-air Treatment

WaterCarb manufactures activated carbons for gas and air treatment. For many applications, Watercarb offers activated carbons to remove various contaminants from gas and air and, in some cases, solutions focused on specific pollutants. An important criterion for the activated carbon used in various systems is the capability of retaining organics and smelling molecules.

This characteristic is mainly based upon the presence of fine micropores that are able to capture the substances. The retention capability can be easily calculated by means of benzene or carbon tetrachloride indexes that allow a prediction on the activated carbon duration and efficiency. Lately also butane index is used to characterize activated carbons for gaseous media treatment. In many problems related to gas purification, low molecular noxious substances, mostly of an inorganic nature, are encountered which can be removed to only a slight degree through adsorption on activated carbon.

Typical cases are, for example, traces of hydrogen sulphide together with natural gas, or air polluted with acidic or alkaline substances. Very often these compounds also occur together with organic vapours which can be eliminated by adsorption. In such cases it is possible to use activated carbons WaterCarb  where activated carbon has been impregnated with different chemical products, that can either bind these low molecular weight noxious materials or convert them into a non-volatile, odour free, form.
