The main goal of this research is to study the feasibility of recovering Phosphorus (P) from industrial and municipal wastewaters in Uruguay with a view to reuse it as a fertilizer. P is a non-renewable and strategic resource, essential for sustainable population growth. Each year in Uruguay, 200,000 tons of P-fertilizer are incorporated to the open P cycle ending in the water bodies. P is usually the limiting nutrient in aquatic ecosystems. The 70% of the Uruguayan water bodies are eutrophic, 20% of the total P present is due to point contamination sources and the other 80 % to field erosion. Because of its concentration, it is more achievable to recover P from point and P rich sources. The experiments in this research evaluate the recovery of the soluble inorganic fraction of the total P in 7 agroindustries with Mg or Ca addition. National data regarding industrial discharges was statistically processed. The industrial areas selected for study were: swine food industries, slaughterhouses, blood meals, feedlots, dairy farms, dairy and cheese industries, and large municipalities. Most companies reached had a positive reaction to the research. A sampling campaign covered 7 industrial areas and 19 samples. The sample characterization included the determination of TP, inorganic P, NH4, Mg, Ca, and COD concentrations, pH and the flow. Except for the municipalities, all the samples had more than 5 mgP/l, the national TP discharge standard. The inorganic P removal efficiency was in most cases above 80% and 90%. The only negative results corresponded to the dairy farm, possibly because of the high solid content in the effluent. Higher P removal efficiency were obtained with Ca addition. The solids obtained were quantified in height and weight. Nutrient content in the inorganic fraction of the precipitates were compared to the commercial fertilizers under EDS (Energy Dispersive X-ray Spectroscopy) and SEM (Scanning Electron Microscopy) techniques. The commercial fertilizers P content rounded 15%. The best result for the inorganic fraction of the precipitates was 25%. The rest of the results are between 5% and 15%. No heavy metals were detected. Higher P % were obtained for Mg-P precipitates. In the preliminary economic analysis P recovery was profitable for the slaughterhouse, swine food industry, feedlot, and the dairy and cheese industry. The IRR (Internal Rate of Return) for the projects were around 20% and the payback period about 4 years.
