In the current work EDR is used for the treatment of heavy metal–contaminated fly ash. The objective is to study the impact of major constituents of fly ash on remediation times, on efficiency, and on the performance of membranes. The results show that major constituents foul the ion-exchange membranes, decreasing their ability to transport metal ions out of the waste compartment.engHeavy metalFly ashIon-exchange membranesElectrodialytic remediationjournal article10.1081/SS-200068412
