Biological removal of H2S gas in a semi-pilot scale biotrickling filter: Optimization of various parameters for efficient removal at high loading rates and low pH conditions

•Semi-pilot scale biotrickling filter (BTF) successfully removed high level of H2S gas.•Elimination capacity increased almost linearly with loading rates up to 38.5 g/m3 h.•H2S at inlet concentrations of 2000 ppm could be removed with >99% efficiency at 15 min retention time.•Acidithiobacillus ca...
