  • Is electrochemical treatment a sustainable alternative to wastewater treatment?
  • Amongst all electrochemical processes, EC stands out as the most sustainable alternative to treat wastewater due to its simple setup, small footprint, ability to treat large quantity of water with no extensive chemical treatment [ 24, 25 ].
  • Can electrochemical oxidation be used in municipal wastewater treatment?
  • The electrochemical oxidation process with an option of microfiltration for real municipal wastewater treatment was investigated in terms of organic matter removal and hydrogen generation. 433 Hydrogen production was enhanced with municipal wastewater due to the presence of specific organics and by adding NaCl to increase conductivity.
  • What are electrochemistry-based methods for removing pollutants in wastewater?
  • In this paper, we reviewed the electrochemistry-based approaches for removal of pollutants in wastewaters, such as electrochemical oxidation, electrochemical reduction, electrocoagulation and electrocoagulation/flotation, and electrodialysis processes.
  • Are electrochemical water treatment strategies adapted to specific waste streams?
  • The first section of this review presents an overview of electrochemical water treatment strategies adapted to these very specific waste streams, including the influence of operating conditions, electrode materials and processes (with special emphasis on anodic oxidation, electro-Fenton and electrocoagulation).
