  • Can electrodialysis be used in wastewater treatment?
  • This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes.
  • Can electrodialysis be used for industrial wastewater containing heavy metal ions?
  • Among the treatment processes proposed for wastewater containing heavy metal ions [ 150 ], electrodialytic methods have been tested for industrial effluents from several processes (metal finishing, leather industry, etc.) aiming at reuse.
  • What are the different types of electrodialytic treatment for industrial wastewater?
  • Waste effluents from industry may have different compositions. However, they often contain dissolved ions. Electrodialytic treatments for industrial wastewater can be classified in: separation of heavy metal ions ( Section 4.1 ); regeneration of acid/base, salt conversion ( Section 4.2 ); desalination ( Section 4.3 ).
  • What is electrodialysis process?
  • Electrodialysis (ED) is a new advanced separation process that is commonly utilized for producing drinking water from water bodies as well as for the treatment of industrial effluents. ED process is applied on commercial scale.
