    Abstract

    This study examined an innovative approach to make use of the Phostrip process to recover phosphorus (P) from municipal wastewater. Returned activated sludge (RAS) from a municipal wastewater treatment plant was systematically studied to examine P release kinetics of RAS in a recovery stream that contained high concentrations of phosphate (PO 4 3- -P). Findings suggested that the specific P release rate in RAS declined with increasing concentration of PO 4 3- -P in the recovery stream. However, there was a strong positive linear correlation between acetate consumed and P released by the RAS (Pearson product-moment correlation coefficient [r = 0.98, n = 45, p < 0.005]). The data also suggest that acetate concentration in the recovery stream was not a factor in the observed reduction of specific P release rate with increasing PO 4 3- -P in the recovery stream. When P release rates (poly-P hydrolysis rate) at different initial P concentrations were modelled using a modified Michaelis-Menten equation, a good fit was achieved between the experimental and the modelled data. According to the model, the maximum specific P release rate (18 mg-P/g-MLSS.h) halved when PO 4 3- -P concentration in the recovery stream reached approximately 83 mg-P/L. Additionally, the RAS demonstrated a P release /C acetate uptake molar ratio of approximately 0.5. An application of the derived P release kinetics into an innovative side stream process configuration showed that a Phostrip tank with a small footprint (9 m 3 ) is sufficient to facilitate P recovery from a wastewater treatment plant that receives 61 ML/d of influent.
