%X The present work aims to use a two-stage biotrickling filters for simultaneous treatment of hydrogen
sulphide (H2S), methyl mercaptan (MM), dimethyl sulphide (DMS) and dimethyl disulphide (DMDS).
The first biofilter was inoculated with Acidithiobacillus thiooxidans (BAT) and the second one with
Thiobacillus thioparus (BTT). For separate feeds of reduced sulphur compounds (RSC), the elimination
capacity (EC) order was DMDS > DMS > MM. The EC values were 9.8 gMM-S/m3/h (BTT; 78% removal
efficiency (RE); empty bed residence time (EBRT) 58 s), 36 gDMDS-S/m3/h (BTT; 94.4% RE; EBRT 76 s) and
57.5 gH2S-S/m3/h (BAT; 92% RE; EBRT 59 s). For the simultaneous removal of RSC in BTT, an increase in the
H2S concentration from 23 to 293 ppmv (EBRT of 59 s) inhibited the RE of DMS (97–84% RE), DMDS
(86–76% RE) and MM (83–67% RE). In the two-stage biofiltration, the RE did not decrease on increasing
the H2S concentration from 75 to 432 ppmv.
