Abstract
Volatile sulfur compounds (VSCs) were identified as the dominant priority odorants emitted from sewers, including hydrogen sulfide (H S), methyl mercaptan (MM), dimethyl disulfide (DMDS) and dimethyl sulfide (DMS). Biotrickling filter (BTF) is a widely-applied technology for odour abatement in sewers because of its relatively low operating cost and efficient H S removal. The authors review the mechanisms and performance of BTF for the removal of these four VSCs, and discuss the key influencing factors including of empty bed residence time (EBRT), pH, temperature, nutrients, water content, trickling operation and packing materials. Besides, measures to improve the VSCs removal in BTF are proposed in the context of key influencing factors. Finally, the review assesses the new challenges of BTF for sewer emissions treatment, namely with respect to the performance of BTF for greenhouse gases (GHG) treatment. 2 2

A STAUNCH anti-dump campaigner says alarming statistics related to the life expectancy and the rates of lung cancer for residents in Ipswich suburbs near waste facilities should be a huge red flag for the state government and needs to be investigated further.
Ipswich Residents Against Toxic Environments secretary Geoff Yarham said the waste industry has already had a “significant effect on people’s amenity and health”.
With a proposed incinerator for Swanbank looming, other waste facilities in the works and Ipswich City Council battling waste operators over the approval of new developments in court, Mr Yarham says anxiety within the community is only rising.
