Abstract: To address industry challenges including low electrophoretic paint recovery rates, excessive pure water consumption and large wastewater discharge of traditional electrophoretic coating lines, this paper draws on design experience from previous renovation projects to optimize the design of electrodialysis reverse osmosis (EDRO) systems and increase ultrafiltration water output, stabilize the state of EDRO stock solution and precisely control effluent water quality. Long-term on-site parameter monitoring and operation data indicate that the adoption of EDRO systems raises the utilization rate of electrophoretic paint to 99%, greatly cuts pure water consumption and realizes zero wastewater discharge in electrophoretic processes, delivering remarkable environmental benefits.
