Biological treatment of gaseous emissions containing dimethyl sulphide generated from pulp and paper industry

A bench scale biofilter packed with compost and wood chips seeded with potential DMS degrading culture (Bacillus sphaericus) could efficiently remove DMS from ambient air with removal efficiency (RE%) of 71 +/- 11 at an effective bed contact time (EBCT) of 360 +/- 20 s with loading rate in the range of 4-28 g(DMS)/m(3)/h. Further, the same biofilter operated for the treatment of vent gas generated from a P&P industry indicated DMS removal of 61 +/- 18% at optimal EBCT of 360 +/- 25 s with a loading rate in the range of 3-128 g(DMS)/m(3)/h.
