EIS - Sacrificial Adsorption Systems

Generally, these are fixed-bed systems that use activated carbon to remove the contaminant, although other materials are available for specialist applications. The contaminant is adsorbed onto the high surface within the material and adsorption continues until the carbon has been fully utilized, at which time it is replaced.

Activated carbon is a carbon that has been chemically, thermally (or both) treated to expose its inner pore structure. This yields the characteristic high surface area found in our carbon products which have surface areas that range from 800-1500 m2/g of material.

The adsorption process works by virtue of a combination of high surface area and electrostatic forces that capture the contaminant within the pore structure of the carbon. This process can be further enhanced by impregnating the surface of the carbon with selected reagents.

This technology offers a reliable and predictable high performance at a very cost-effective capital outlay.
