dc.description.abstract | A phosphorus crystallization process for recovering phosphates was developed using a completely mixed reactor and powdered converter slag as a seed crystal. This completely mixed phosphorus crystallization process achieved a stable and high phosphorus recovery: the average PO4-P removal efficiency during 200 d of operation was 87%, with a range of 70-98%. The apparent volume of the slag doubled due to crystal growth during the long-term phosphorus-removal experiments. The Ca2+ concentration, slag dosage, and temperature were found to govern the phosphorus recovery system for a given condition of pH and hydraulic retention time. The equations for the rate constant and reaction order were obtained by evaluating the model parameters. The model developed in this study was observed to successfully simulate the behavior of effluent PO4-P in a completely mixed phosphorus crystallization reactor over a wide variety of operating conditions of temperature, Ca2+ concentration, and influent PO4-P. Model investigations of design factors suggest that the completely mixed phosphorus crystallization process with influent PO4-P concentrations of less than 10 mg l(-1) could ensure effluent PO4-P concentrations of less than 0.5 and 1.0 mg l(-1) during summer and winter in Korea, respectively.
