dc.description.abstractPhosphorus (P) scarcity, jointly with eutrophication problems and water shortage, are forcing urban wastewater treatment plants (WWTP) to redirect their focus to nutrient recov-ery and treated water reuse. However, before implementing any recovery approach, it is neces-sary to understand the problem and its variability. In this scope, this work aims to collect data from different WWTP to assess P concentrations, speciation, and variability in urban wastewater. The analysis revealed high levels of total P, before and after anaerobic digestion, and in the sludge dewatering water (100-400 mg P/L), with about 60-80% of total P in the solu-ble form. Also, in the best-case scenario, soluble reactive P (orthophosphate) accounts for over 50% of soluble total P. Preliminary results showed that it would be possible to recover over 100 kg P/day in a WWTP with about 160,000 p.e.pt_PT
