Exen’s activated carbon odor control system consists of a variety of adsorbent media, such as activated carbon, impregnated activated carbon, and alumina-based and specially formulated activated carbon. Appropriate activated carbon is used, depending on on-site conditions and, in particular, properties and concentrations of malodorants, for the purpose of maximizing the adsorption of malodorants. With these, it is assured that there is a high efficiency and an extension of the replacement period.
