This work applied fluidized-bed crystallization (FBC) and fluidized-bed homogeneous crystallization (FBHC) to recover iron-contaminating from wastewater as iron oxide particles, such as FeOOH, Fe3O4, and FeCu@SiO2. The crystal of FeOOH was recovered from synthetic wastewater at the optimum value of pH 6.5 – 7.5, surface loading (L) of 0.6 kg/m2/h for an input ferrous concentration ([Fe2+]in) of 100-300 mg/L, resulting in the total iron removal (TR) of more than 99% and crystallization ratio (CR) of 85%. The X-ray diffractometry (XRD) analysis showed that the pellet product was a mixture of iron oxyhydroxide polymorph, including goethite (α-FeOOH), and lepidocrocite (γ-FeOOH). The magnetite (Fe3O4) was obtained under the conditions of pH = 8.5-9.5 and (Fe2+)in = 100 – 500 mg/l, the TR and CR values were 99% and 77%, respectively. The highly pure Fe3O4 pellets (average size: 0.5 – 0.7 mm) obtained from FBHC had high magnetization and low coercivity values of 79.45 emu/g and 5.6 Oe, respectively, indicating the property of superparamagnetism of recovered magnetite. A Fenton-like reaction of RB5 azo dye was catalyzed with the Fe3O4 pellets under conditions of UVA irradiation, pH = 2.75 – 3.0, initial peroxide concentration of 10 mM (340 mg/L), and catalyst loading of 2 g/l. The efficiencies of decolorization and mineralization reached about 99% and 68%, respectively. Iron and copper were also removed from synthetic wastewater as binary oxide compound coated on the surface of the silica seed. Under the optimum pH of 7.5 – 8.5, about 90% and >99% of iron and copper could be removed for CR and TR respectively.
