Dispersion Modeling to Compare Alternative Technologies for Odor Remediation at Swine Facilities

Modeling Odor Dispersion From a Swine Facility Using AERMOD

Meteorological conditions, odor emissions, and ambient odor levels at a four-barn, swine finishing facility in Iowa were measured in the summer and fall of 2004. This paper compares ambient odor levels measured using a Nasal Ranger® compared to those predicted by AERMOD, a relatively new air dispersion model. Scaling factors needed to adjust predicted odor levels to those observed ranged from 1...

Comparison of Odor Dispersion at Swine Facilities and a Waste Processing Center Using a Eulerian-lagrangian Model

The purpose of this report is to compare odor dispersion at swine facilities that use alternative waste technologies (as well as a waste processing center) with odor dispersion at two control farms that use conventional lagoon technology. The goal was to determine if these alternative technologies reduce or substantially eliminate the emission of odor that is detectable beyond the boundaries of...

Controlling Odor and Gaseous Emission Problems from Industrial Swine Facilities

Application of A Gaussian Plume Model of Odor Dispersion To Select A Site For Livestock Facilities

The ideal separation distance between a livestock facility and the nearest neighbor to avoid an odor nuisance has not been determined and is somewhat subjective. A windows based computer program was developed to be used as an educational tool and decision aid for planning livestock facilities. The major focus is on control and dispersion of odor, with a secondary emphasis on nutrient management...

Correlation of Sensory Analysis with Electronic Nose Data for Swine Odor Remediation Assesment

This article presents an evaluation of the electronic nose technology as an alternative to sensory analysis for assessing the effectiveness of biofilters. An AromaScan A32S electronic nose and a human panel at Duke University’s Taste and Smell Research Lab were used to measure typical volatile compounds from swine confinement buildings. Chemometrics techniques were employed to predict the olfac...
