Metso Outotec launches compact AC filter for efficient removal of organics in battery metal processes

Metso Outotec introduces the Activated Carbon (AC) filter for efficient recovery and recycling of valuable battery chemicals. The energy and water efficient AC filter responds to growing market demand for advanced and sustainable battery metal processing technologies and is part of Metso Outotec’s Planet Positive portfolio.

“This launch will strengthen our ability to serve a wide variety of industries and processes. With the Dual Media (DM) filter, Metso Outotec now has a complete range of filtration for Solvent Extraction (SX), Electrowinning (EW) and Crystallization processes. We have strong hydrometallurgical industry know-how with more than 50 references of successful SX filtration solutions and crystallization processes worldwide,” says Mika Vuorikari, Industrial Filtration Manager at Metso Outotec.

Modular AC filtration technology is designed for small copper sidestreams and other metal-laden aqueous streams. It is particularly suitable for efficient removal of organic materials prior to electrowinning and crystallization processes. The AC filter uses the already proven design and operating philosophy of the Metso Outotec DM filter product family and is suitable for both greenfield and brownfield installations.

Advantages of the AC filter:

  • Increased yield and quality of the final product
  • Increased recovery and recycling of valuable process chemicals
  • Economical and modular design
  • Low energy consumption, thanks to low pumping pressure
  • Minimized water consumption with optimized backwashing
  • Safe to use and operate, thanks to sealed pressure tank and piping
