Unravelling the potential of combined electrodialysis/electrocoagulation for boosted dye removal and membrane anti-fouling activity.

Membrane fouling is the major technology issue facing the wide application of electrodialysis (ED) for water purification in real world cases. The fouling of membrane in ED leads to reduce the removal rate, increase in membrane damage, and it requires continuous costly maintenance. Herein, a successful dual process combining ED and electrocoagulation (EC) was designed to combat anionic membrane (AMX) fouling and to boost organic dye pollutant (methyl orange, (MO)) removal efficiency.
