Biological air filters have been proposed as a cost-effective technology for reducing odor emissions from intensive swine production facilities. In this work we present results from the application of membrane inlet mass spectrometry (MIMS) for conti

Emissions of odor and ammonia from small-scale pig finishing units were reduced by 40 % as a result of mechanical and chemical treatment of the slurry. Once a week, the pits were drained, and the slurry was separated mechanically using polymers, then

Single odorants in the outlet air from swine units have been measured by sampling air on adsorption tubes followed by analysis by GC-MS (Gas Chromatography - Mass Spectrometry). Additionally, online measurements by MIMS (Membrane Inlet Mass Spectrome

When treating swine slurry with ozone, the slurry is divided into fractions. It is divided into a thin fraction, a thick fraction, and a foam fraction. This is used in connection with a brand new system for reducing odour from swine production units.

Ammonia released in pig production industries can lead to eutrophication of surface waters, soil acidification, fertilization of vegetation and changes in ecosystems, etc. Air scrubbers with spray of aerosolized sulphur solution were used to remove t
