Investigation and modeling of odors release from membrane holes on daily overlay in a landfill and its impact on landfill odor control

Sami Rtimi

In the present work, we studied the NH(3)and H2S odor fluxes between the exposed working area and the HDPE covering film holes of the daily overlay in an actual landfill site with a daily operating area of 1600 m(2)in Hangzhou, China. We showed that the od ...
