Summary on Grant Application Form |

Granular activated carbon (GAC) is gaining increasing prominence in the treatment of potable waters for the adsorption capacity of GAC is restored by thermal regeneration and the GAC re-used. However, substantial amounts of inorganic metal species are also adsorbed and accumulate on the surface of GAC filter media. These species are important as many metals can catalyse the oxidation reactions that occur during thermal regeneration processes and, hence may lead to a deterioration in the porous and adsorption characteristics of GAC filter media, a consequential decrease in its performance and, potentially, a significant increase in the process costs. This project will constitute generic research evaluating the effects of metals during the thermal regeneration of GAC adsorbents and will investigate the influence of individual metal cations, metal-associated anions, GAC types, acid washing, both before and after regeneration, and both pyrolysis and reactivation temperatures on the subsequent porous and trace organics adsorption characteristics of GAC adsorbents.
