  • Low energy consumption due to low pumping pressure
  • Increases the quality and intake of the plant’s end product
  • Suitable for both greenfield and brownfield operations
  • Increases recovery and recycling of valuable process chemicals
  • Safe to use and operate due to sealed pressure vessel and piping

AC filter is used to remove organics in battery metals processes. It strengthens the existing Metso Outotec filtration portfolio with the capability to serve a larger variety of industries and processes. Together with the Dual Media (DM) filter, Metso Outotec now has a complete filtration portfolio for solvent extraction (SX), electrowinning and crystallization processes.

AC filter becomes an ideal choice when the solution is already free from suspended solids and when a very clean solution filtrate is needed. It is also used for raffinates, when a very clean solution is needed to follow SX steps in order to ensure that the remaining solvents and reagents from previous extraction step do not pass to the following step.
