Abstract :As the global population continues to grow rapidly, fertilizers are becoming increasingly crucial for ensuring the security of food supply. Because phosphate is the key component in fertilizers, there is an increasing demand for alternative phosphate (PO43-) sources. The forward osmosis (FO) process has gained more attention recently as a promising, low-cost and low-fouling membrane process for nutrient concentration and recovery. In this study, the efficiency of the FO process was evaluated in recovering PO43- from pre-treated municipal wastewater. The effectiveness of the FO process was investigated using two different draw solutions (MgCl2 and NaOAc) at two different concentrations (1 and 2 M) and two different recovery rates (60% and 80%). The highest PO43- concentration of 23.20 mg/L was obtained in FO experiments at 60% recovery rate and with the concentration of the 2 M MgCl2 draw solution.Keywords : İleri Ozmoz, Nütrient Geri Kazanımı, Membran Filtrasyon, Evsel Atıksu
