| Popis: | The daily demand of demineralized water (DMW) in electrolytic galvanizing line (EGL) in China Steel Corporation (CSC) reached approximately 1,600 m3 as the production line was fully in operation. However, the wastewater produced from the EGL was discharged into the cold-rolling mill wastewater treatment plant even though it had potential for reclamation. This study provides details of design and parameter optimization of a full-scale wastewater reclamation plant for the EGL. Three wastewater streams including hot water rinse, pickling rinse wastewater, and condensate water from the EGL were selected for reclamation. The full-scale wastewater reclamation plant was constructed to equip with coagulation, flocculation, sedimentation, and filtration for pretreatment, and electrodialysis reversal (EDR) and ion exchange (IX) processes for desalination. The pretreatment process can reduce the total iron concentrations in the wastewater from 40–70 ppm to |
