background: the air dispersion models are widely used to evaluate and predict the pollutants emissions from air pollution sources such as incinerators. this study attempts to predict the heavy metal pollutants dispersion emitted by an incineration plant impacting its surrounding area. methods: several scenarios of emission rates coupled with the meteorological conditions were investigated using...

Biofiltration has become a widely accepted technology for the removal of hydrogen sulfide (H2S) which is one of the major odor causing gases present in the air streams of municipal wastewater treatment facilities. In addition to odorous nature, H2S is toxic and corrosive. In this study, a biofilter which uses a novel media was employed in a pumping station which is closely located at the Univer...
