Abstract
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.
