Adsorption Systems
Evoqua's adsorber systems contain granular activated carbon that facilitate the transfer of contaminants onto the media as the vapor or liquid stream passes through one or more vessels. When the contaminant level in the carbon bed reaches the saturation point, the carbon is removed and regenerated at an off-site facility or removed and disposed.

Adsorption is a unit operation that involves the contact of a solid phase with a fluid phase (liquid or gas) (Ruthven 1984). In this work, only the solid–liquid adsorption is addressed. The solid phase is known as adsorbent and the liquid phase (the solvent, normally water) contains one or more compounds to be adsorbed (the adsorbates).
