Using Tall Fescue to Remove Nutrients from Renovated Turkey Processing Wastewater

The aim of this study is to use commercially valuable ornamental plants, such as tall fescue, for wastewater treatment without decreasing the overall treatment efficiencies of a greenhouse-based hydroponic system. The wastewater, from a turkey processing plant, was treated in a sand bioreactor system. Reduction of nitrate and phosphorus from wastewater was quantified in the influent and effluent to evaluate the performance of the greenhouse-based hydroponic system. Tall fescue was cultured on media consisting of perforated plastic plates and one layer burlap. The plate/fabric/ grass cells with different hydraulic retention time were studied. The results show that there is no significant difference in treatment between 3, 4 and 5-days hydraulic retention time. With 1-day of retention time nutrient removal fluctuated. Two days of retention achieved 60% NO3--N removal and 75% PO43--P and was considered optimal for nutrient removal.
