Copper Foil Production

    In the production of copper foil for printed circuit boards and lithium-ion batteries, maintaining electrolyte purity is essential for consistent quality. During electro-deposition, insoluble particles such as copper fines, anode sludge, and additives degrade the electrolyte and lead to surface defects in the final foil.JOECHRE filtration systems provide continuous clarification of the electrolyte solution, removing fine particles without interrupting the process. Our fully enclosed design minimizes contamination risk while reducing maintenance and operator exposure. Optional filter aid dosing enhances cake formation and improves filtrate clarity. The system’s back-flushable elements allow for stable long-term performance, making it ideal for both batch and continuous copper foil production lines.​
