Biogenic taste and odour (T however, the evolution of biofilms in BAC systems and how it affects biofiltration performance of T approximately 90% removal of T&O compounds was observed and, of the total, 90% was removed within the first 72 hours as determined via the newly developed batch adsorption test. Pre-exposure to T&O had little to no effect on the BACs capacity to remove these compounds. These results indicate that adsorption still plays a major role in T&O removal even after the system has become BAC and attests to the resilience of BAC systems against intermittent periods of non-exposure to T&O. • Micropore volume had strong correlation with taste and odour adsorption. • Taste and odour removal remained high after perceived adsorption exhaustion. • Pre-exposure to taste and odour compounds had little effect on their removability. • Similar removal kinetics observed between aged and fresh granular activated carbon.
