To investigate the effects of bioaugmentation strategies on the removal of phenolic compounds in UASB reactors.
Used two series of UASB reactors with unacclimatized granular sludges.
Applied bioaugmentation with a methanogenic consortium enriched for phenolic compounds.
Tested two immobilization methods: adsorption to biomass and encapsulation in calcium alginate beads.
Measured phenol, o-cresol, and p-cresol removal rates over time.
Complete phenol removal achieved in bioaugmented reactor after 36 days, compared to 178 days in control.
95% p-cresol removal in bioaugmented reactor by day 48, versus 60 days in control.
Marginally better results for o-cresol in bioaugmented reactors.
Higher specific activities for bioaugmented biomass compared to original after 276 days.
Best activities were achieved with encapsulated consortium, showing effective initial and sustained removal.
