The variation in phosphorus (P) speciation of sewage sludge throughout three wastewater treatment plants (WWTPs) was obtained by combining sequential P extraction with optical and scanning electron microscopy (SEM), chemical analyses, powder X-ray diffraction (PXRD), 27Al 31P nuclear magnetic resonance (NMR) spectroscopy. WWTPs combine removal (CPR) enhanced biological (EBPR) were compared to understand the effect iron (Fe) dosing without codosing aluminum (Al) thermal hydrolysis on speciation. NMR showed comparable inorganic orthophosphate (ortho-P, 53–60% total P) organophosphate (organic-P, 37–45%) primary sludge, whereas polyphosphate (poly-P, 23–44%) from poly-P accumulating organisms (PAOs) mainly observed secondary sludge. Inorganic ortho-P (90–98%) dominated after anaerobic digestion, which degraded most organic-P. Fe bound (Fe-P), especially digestion (71%). Codosing Al led two fractions: Fe-P (38%) sorbed amorphous (hydr)oxides (38%). Vivianite identified all samples but PXRD 12 out 17 samples. Thus, vivianite may be more common than previously known.
