Abstract
This paper presents experiments of struvite crystallization (MgNH4PO4.6H2O)on a stirred-batch lab. The optimizing parameters, namely solution temperature (30, 35 and 40 C), tartaric acid concentration (1, 10 and 20 ppm),stirring speed (200, 250 and 300 rpm), were using Response Surface Methodology to provide the optimum yield of the mass scales. The tartaric 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 in the Response Surface Methodology. The optimum mass scale response of 10.483 mg was obtained at a temperature of 36 o C, stirring speed of 260 rpm and tartaric acid concentration of 18 ppm, respectively. This gave the best combination of process parameters for struvite crystallization in liquid waste as fertilizer materials.
