Wood-based granular activated carbon (GAC) has been used successfully both in
pilot applications and in full-scale filter applications, but its durability during
backwashing has not been evaluated in a side-by-side study with bituminous coal-based
GAC. The objective of this study was to compare the durability of these two
types of GAC when subjected to 500 cycles of backwashing with an air-water wash
system. GAC durability was evaluated by measuring the change in carbon bed height,
pressure drop, filter effluent water quality, and particle characteristics as a function
of backwashing. The results showed that the durability of the wood-based and the
coal-based GAC was similar throughout the duration of the study. Includes 16 references, tables, figures.
