The Effects of Thermal Regeneration Conditions and Inorganic Compounds on the Characteristics of Activated Carbon Used in Power Plant

Activated carbon filters are widely used to eliminate the contaminants in water, especially in power plant water treatment. Once exhausted, its adsorption capacity is normally recovered by thermal regeneration, and then activated carbon is reused. This paper summarizes the process of thermal GAC (Granular Activated Carbon) regeneration and the factors in this process. Inorganic salts adsorbed in GAC could play a negative role during catalyzed oxidation reactions when GAC is regenerated and lead to deterioration of its adsorbent properties.
