Interpretive Summary:

Technical Abstract: This study evaluated several potential alternative treatment techniques that can be used in conjunction with primary treatment (e.g., solids separation, anaerobic lagoons) to provide improved, cost-effective treatment of swine waste. The results of this economic analysis indicate that a surface-flow constructed wetland system alone can provide the most cost-effective secondary treatment for removal of nitrogen and microbial indicators of fecal contamination in swine wastewater. It was more cost effective than composite nitrifying media filter followed by constructed wetlands or overland flow followed by constructed wetlands. The results of this study raise the prospect that swine waste treatment systems using primary treatment techniques other than lagoons (e.g., solids separators) in conjunction with constructed wetlands may be capable of providing similar, or improved, nutrient and enteric microbe removal as is achieved using lagoon treatment, thereby avoiding the use of anaerobic lagoons.
