Application of electro-dialysis on removal of heavy metals

WebThis heterogeneous cation exchange membranes used in electrodialysis process for water treatment. ... batch electrodialysis process was … Electrodialysis (ED) is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential difference. This is done in a configuration called an electrodialysis cell. The cell consists of a feed (dilute) compartment and a … See more In an electrodialysis stack, the dilute (D) feed stream, brine or concentrate (C) stream, and electrode (E) stream are allowed to flow through the appropriate cell compartments formed by the ion-exchange membranes. … See more Current efficiency is a measure of how effective ions are transported across the ion-exchange membranes for a given applied current. … See more In application, electrodialysis systems can be operated as continuous production or batch production processes. In a continuous process, feed is passed through a sufficient … See more Electrodialysis has inherent limitations, working best at removing low molecular weight ionic components from a feed stream. Non-charged, higher molecular weight, and less mobile ionic species will not typically be significantly removed. Also, in contrast to … See more Reactions take place at each electrode. At the cathode, 2e + 2 H2O → H2 (g) + 2 OH while at the anode, H2O → 2 H + ½ O2 … See more Selective electrodialysis uses ion selective exchange membranes to concentrate only some ions, whereas other species remain in the diluted channel.
