Using a Hydroponic System with Tall Fescue to Remove Nitrogen and Phosphorus from Renovated Turkey Processing Wastewater

Even after wastewater has been treated, nitrogen and phosphorus levels can be high. The aim of this study was to use tall fescue for post wastewater treatment without decreasing the overall efficiency of the main treatment system. The wastewater source used in this experiment was from a turkey processing plant. To measure the removal of nitrogen and phosphorus, the wastewater was tested before and after going through the system. The tall fescue system was able to remove on average 14% of nitrogen and 42% of phosphorus. Further research in the biological mechanisms of nutrient removal could improve the removal rates.
