A biotrickling filter packed with ceramic particles and seeded with B350 microorganisms was applied to remove trimethylamine (TMA) from gaseous waste. A 100% removal efficiency (RE) was obtained when the empty bed residence time (EBRT) was larger than 110 s at an inlet concentration of 0.30 mg/L. Maximum elimination capacity (EC) was 13.13 g m(-3) h(-1) (RE = 64.7%) at 55s of EBRT. TMA concentrations < 0.20 mg/L at 83s of EBRT did not affect the REs (100%). Maximum EC was 13.95 g m(-3) h(-1) (RE = 78.1%) at a TMA concentration of 0.42 mg/L Approximately 53.1% of the carbon in TMA was completely mineralized. Bacterial community analysis in the bioreactor revealed more than 21 species in a stable state. Based on all these results, biotrickling filter inoculated with B350 microorganisms is deemed highly capable of ridding waste gas of TMA. (C) 2011 Elsevier Ltd. All rights reserved.
