Probing fouling mechanism of anion exchange membranes used in electrodialysis self-reversible treatment by humic acid and calcium ions

When humic substances (HS) are present in the feed water, fouling of ion-exchange membranes is inevitable despite the built-in self-cleaning process of electrodialysis reversal systems (EDR). When Ca2+ is present in water, HS can readily chelate with them and form organic-Ca2+ complexes, which can f...
