Air emissions from animal housing systems are being examined more closely for ways to mitigate potentially harmful gases. Wet scrubbers are one way to remove pollutants from air being exhausted from mechanically ventilated buildings.  The materials on this page were developed to assist educators and professors who include wet scrubbers as a topic in their classrooms or educational programs.
