Tests conducted by the University of Minnesota's College of Agriculture found the Tornado Aerator from Aeromix Systems was found to significantly reduce odor. Two 5-Hp Tornado Aspirating Aerators were installed in a waster water lagoon at a large hog confinement facility. Samples were taken for over a one year period, and the aerated lagoon's odors were reduced by as much as 75 percent. H2S levels were as much as 90 percent lower than the non-aerated basin. Reduced odor was also noticed in the buildings. ©
