High phosphorus concentrations in wastewater effluent can have harmful effects to aquatic environments and water quality. An excess of nutrients such as phosphorus in water bodies will cause eutrophication, which depletes the available oxygen within the water and is detrimental to aquatic life. Additionally, phosphorus leaching from wastewater discharge has negative impacts to groundwater quality. The depletion of phosphorus as a natural resource is also of concern as phosphorus is an essential product for agricultural and industrial production. Phosphorus is a non-renewable resource, and natural sources are becoming more difficult and expensive to access. Therefore, the removal and recycle of phosphorus from wastewater is an important area of research. Several methods of phosphorus removal and recovery as part of the wastewater treatment process exist and are applicable on a practical scale. Livestock wastewater streams, such as swine wastewater, have particularly high concentrations of phosphorus which makes them good candidates for phosphorus recovery processes. This study compares existing phosphorus removal methods and selects a proposed treatment technology for an assumed swine production facility.
