Launched last month, the energy- and water-efficient AC (activated carbon) filter responds to the market’s increasing demand for advanced and sustainable battery-metals processing technologies. The modular AC filtration technology (photo) is designed for smaller side streams of copper and other metal-loaded aqueous streams. It is specifically suited for efficient organics removal before the electrowinning and crystallization processes. The AC filter utilizes the already proven design and operation philosophy of the company’s DM filter product family and is suitable for both greenfield and brownfield installations. Benefits of the AC filter include: increased end-product yield and quality; increased recovery and recycling of valuable process chemicals; low energy consumption, due to low pumping pressure; and minimized water consumption with optimized back washing. — Metso Outotec Corp., Helsinki, Finland
