Elimination of metal ions

Electrochemical crystallization

Intending to reduce metal ions from a fluid standard filter systems often reach their limits. The electrochemical crystallization process allows discharging of metal ions electrochemically to atoms, which will then accumulate on an electrode. The basic system (see picture to the right) is similar to a reactor for galvo-technical processes.

Material of electrodes

Adapted to the problem at hand GTWE uses different cathode materials fitting to the respective metal atoms. Special GTWE electrodes are used for the electrochemical crystallization process suppressing the dissolution of the anodes.


Fields of application

Using electrochemical crystallization many metals can be removed from the fluid, including:

  • arsenic
  • lead
  • chromium
  • copper
  • manganese
  • nickel



GTWE electrochemical crystallization units stand out due to:

  • Stability of the special GTWE electrodes
  • Superior uptime
  • Cheap kathodes
  • Small footprint
  • Robustness
