The application of the Fluidized-Bed Crystallization process to recover iron and copper simultaneously as binary oxide particles from synthetic wastewater

The simultaneous recovery of iron and copper from synthetic wastewater as binary oxide particles of FeIII0.66CuI0.33@SiO2 was successfully experimented with through the Fluidized-bed crystallization (FBC) process. The operating parameters, including pH and cross-sectional surface loading, were optimized to obtain the highest crystallization efficiency. The different seed materials and organic contaminations were tested. The potential disposal cost-down was also calculated. Under the optimum conditions of pH = 7.5 - 8.5, [Fe(II)]in / [Cu(II)]in = 2 / 1, and total inlet metal concentration of 3 mM. The crystallization ratio (CR) reached 90% for both iron and copper with the corresponding total removal (TR) of >99%. There was no significant effect of removal efficiency in the different supported seed materials. However the CR and TR for iron decreased to 29% and 44.57%, respectively and the CR and TR of copper also decreased to 32.1% and 39.8%, respectively under the contamination of chelating agents that was represented by EDTA. XRD and XPS analysis clearly shows that the iron oxide and copper oxide coated species exist as &#945--FeOOH and Cu2O. FBC is a promising process to recover heavy metal-containing wastewater as low moisture particles that successfully reduced sludge production and cut disposal costs by up to 36%.
