For separate feeds of reduced sulphur compounds (RSC), the eliminationcapacity (EC) order was DMDS > DMS > MM. The EC values were 9.8 gMM-S/m3/h (BTT; 78% removalefficiency (RE); empty bed residence time (EBRT) 58 s), 36 gDMDS-S/m3/h (BTT; 94.4% RE; EBRT 76 s) and57.5 gH2S-S/m3/h (BAT; 92% RE; EBRT 59 s). For the simultaneous removal of RSC in BTT, an increase in theH2S 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 increasingthe H2S concentration from 75 to 432 ppmv.
