Electrodeionization removal of HCrO4- ions from diluted solution. Effect of membrane
(2016) Dzyazko, Yulia; Arar, Özgur; Rozhdestvenska, Lyudmyla; Vasilyuk, Sergey
Transport of chromate ions in the systems involving granulated ionexchangers and anion-exchange membranes of different origin was researched under various voltage. The role of the membranes as sorption barrier was considered. The method that allows one to estimate mobility of sorbed ions through ion-exchanger bed has been proposed. Electrodeionization of Cr(VI)- containing solution using inorganic ion exchange materials was studied.

In this study, treatment of ground water used in a fruit juice company located in İzmir city by integrated nanofiltration (NF), electrodialysis (ED) and electrodeionization (EDI) methods was studied. For this purpose, the ground water obtained from the plant was treated by using two different NF membranes (NF-90 and NF-270). The brine from both NF membranes was fed to ED stack. The ED diluate was further treated by EDI process for ultrapure water production.
