Abstract. The aim of this study was to use commercially valuable ornamental plants, such as tall fescue, for wastewater treatment without decreasing the overall treatment efficiencies of a laboratory-scale hydroponic system. The wastewater, from a turkey processing plant, was treated in a sand bioreactor system. Nitrate and phosphorus were measured in wastewater influent and effluent to evaluate the nutrient removal performance of the laboratory-scale hydroponic system. Tall fescue was cultured on media consisting of perforated plastic plates and one layer burlap. The plate/fabric/grass cells were tested at different hydraulic retention times. Two days of retention achieved 53% NO3--N removal and 68% PO43--P and was considered optimal for nutrient removal at 22-28 days of growth.
