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

摘要

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±20s with loading rate in the range of 4-28g_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±25s with a loading rate in the range of 3-128g_DMS/m~3/h.
