Metso Full portfolio Activated Carbon (AC) filter

Activated Carbon (AC) filter

Advanced recovery, compact design

Designed to remove organics in battery metals, the Activated Carbon (AC) filter is based on nearly a century of experience and strengthens the Metso filtration portfolio even further with its cost effective and modular design, increasing recovery and recycling of valuable process chemicals.

4 different filter sizes

Up to 15% less energy usage due to low operation pressure and lacking of moving parts

Up to 90% reduced water consumption due to use of filtrate in filter back wash

  • Utilizes the already proven cost-effective, modular design and operation philosophy as in the Metso DM filter product family
  • 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 filtration portfolio with the capability to serve a larger variety of industries and processes. Together with the Dual Media (DM) filter, Metso 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.
