Use of Nanoparticles to Control Gaseous Emissions from Swine Manure Slurry
Nanoparticles have unique properties due to nanoscale dimension and are highly reactive powder materials. Nanotechnology may allow odour and gas emission control from swine operations. Impact on ammonia, carbon dioxide, hydrogen sulphide and gas mixture from swine slurry by commercially available nanoparticles was examined. A few nanoparticles could reduce 25 ppm hydrogen sulphide to below detection level (<1 ppm) while a number of nanoparticles could reduce ammonia by 78 to 86%. Practical implementation will be studied further.
