Researchers studying nutrient removal capabilities in constructed wetlands have observed odor reductions in livestock facility wastewater being treated in these systems. Constructed wetlands, therefore, offer livestock producers an alternative wastewater management system that could significantly reduce nuisance odors, in addition to providing wastewater treatment. The goal of this research has been to quantify the reduction of malodor in swine facility wastewater treated in constructed wetlands to develop an efficacious odor-abatement technology for on-farm application.

520 $a Researchers studying nutrient removal capabilities in constructed wetlands have observed odor reductions in livestock facility wastewater being treated in these systems. Constructed wetlands, therefore, offer livestock producers an alternative wastewater management system that could significantly reduce nuisance odors, in addition to providing wastewater treatment. The goal of this research has been to quantify the reduction of malodor in swine facility wastewater treated in constructed wetlands to develop an efficacious odor-abatement technology for on-farm application.
520 $a Planted and unplanted subsurface-flow constructed wetlands were used to examine odor reduction from swine facility wastewater. Odor reduction was measured by quantifying the concentrations of dimethyl disulfide and <italic> p</italic>-cresol and by using a human sensory panel to rate odor intensity and offensiveness levels of treated and untreated wastewater. Both planted and unplanted wetlands removed over 50 percent of dimethyl disulfide and <italic> p</italic>-cresol. Furthermore, odor intensity and offensiveness levels were significantly lower in treated than in untreated swine facility wastewater. Planted wetlands were found to provide more efficient odor removal treatment than unplanted wetlands.
520 $a The reliability of the cloth swatch olfactometric technique used by an eight member human sensory panel was evaluated. Reliability was based on the repeatability of odor ratings assigned by panelists to sample replicates. A majority of panelists gave consistent odor intensity and offensiveness level ratings. The cloth swatch technique was, therefore, determined to be reliable for subjective odor quantification.
520 $a The effect of wetland oxygen conditions on dimethyl disulfide and <italic> p</italic>-cresol concentrations was studied. Redox potentials and malodorous compound concentrations were measured at two wetland depths representing root and non-root zones. Reduced conditions were found in both planted and unplanted wetlands, however, dimethyl disulfide and <italic>p</italic>-cresol concentrations were significantly lower in the planted wetland root zone than in other wetland locations. Overall, constructed wetlands are an efficacious odor-abatement technology for the treatment of swine facility wastewater.
