Characteristics of ground granular activated carbon for rapid small scale column tests

Keywords and Phrases

Isoelectric potential; Brunauer-Emmett-Teller (BET) surface area; Rapid small scale column test (RSSCT)


"The rapid small scale column test (RSSCT) has become a popular method to characterize and size granulated activated carbon (GAC) for water treatment facilities. In the procedure the GAC is ground and a specific size fraction is used in the RSSCT. Since GAC is produced and activated using different processes from different starting materials (e.g. bituminous, lignite, wood, etc.) there exists the possibility for a variation in the sorptive capacity and surface reactivity through out the particle, such as a less activated inner core of the particle. This could lead to a biasing of experiment scale-up results since only a specific size fraction is used. This study was carried out to determine if there is any variation in the surface properties of the activated carbon through the various size fractions. Four activated carbons manufactured from different source carbons were studied"--Abstract, leaf iv.
