Direct electrowinning is pushed to the extreme with emewPolish. Using the same concept of high-efficiency emew electrowinning equipped with a sophisticated, proprietary high surface area cathode, this type of emew cell can recover metals down to less than 5ppm. Not possible with conventional electrowinning technology, the emewPolish cell is ideal for recovering metals from dilute concentration bleed streams, wastewater or any industrial process stream with low metals concentration.  

Applications for emewPolish include:

  • Silver refineries looking for an alternative to AgCl to treat bleed streams and spent electrolyte
  • Zinc refineries looking to minimize zinc dust usage to remove copper, cadmium, bismuth and others during zinc electrolyte purification
  • Any industrial wastewater that is too dilute to be treated by conventional means
