Abstract
This paper presents results of an investigation of scaling of magnesium ammonium phosphate hexahydrate (struvite) on a process batch crystallizer. In this study, variables, namely temperature (30-40oC), stirring speed (200-400 rpm), maleic acid concentration (1-20 ppm) were optimized using RSM (response surface methodology) to provide the optimum yield of the mass scales. The RSM prediction provided that the maleic acid concentration was the most significant factor for scale yield, while the temperature and the stirring speed were insignificant factors determining the optimal condition of the mass scale yields. The optimum mass scale response of 10.43 mg was obtained at a temperature of 30 oC, stirring speed of 300 rpm and maleic acid concentration of 20 ppm, respectively. This gave the best combination of process parameters for struvite crystallization in an aqueous solution
