Two identical biotrickling filters named BTFa and BTFb were run in parallel to examine their performances in removing hydrogen sulfide. BTFa was filled with ceramic granules, and BTFb was filled with volcanic rocks. The results showed that BTFb was more robust than BTFa under acidic conditions. At empty bed residence times (EBRTs) of 20 and 15 s, the removal efficiency of BTFa was close to 100%. At EBRTs of 10 and 5 s, the removal efficiency of BTFa slightly decreased. The removal efficiencies of BTFa decreased by different degrees at the end of each stage, dropping to 94%, 81%, 60%, and 71%, respectively. However, the H2S removal efficiency in BTFb consistently reached 99% throughout the experiment. Pyrosequencing analyses indicated that members of Thiomonas dominated in both BTFs, but the relative abundance of Acidithiobacillus was higher in BTFb than in BTFa.
