Selection framework for the treatment of sewer network emissions.

Increasing urban growth and lifestyle expectations have led to an increase in public complaints against odours from sewer infrastructure. Gas phase odour abatement in sewer networks, particularly at sewer pumping stations, is most commonly achieved by using biofilters, biotrickling filters or activated carbon filters. When odour complaints are received, a typical response is to close vents, leading to biogenic corrosion in sewers, which increases operating costs.
