“…Again heterogeneous SAN-ion exchange membranes showed similar results in the electrodialysis process in comparison with high performance membranes found in the existing literature (Güvenç and Karabacakolu, 2005;Chen et al, 2009;Dalla Costa et al, 2002;Tanaka, 2002;Cifuentes et al, 2009;Parulekar, 1998;Melnyk and Goncharuk, 2009). The experimental results confirmed that the potentiostatic control is safer then the galvanostatic control, by avoiding the concentration polarization phenomena (Güvenç and Karabacakolu, 2005;Chen et al, 2009;Dalla Costa et al, 2002;Tanaka, 2002) and development of high voltages at low final concentration in the final electrolyte.…”

“…42 A formação destes precipitados constitui-se em uma limitação 43 da aplicação do tratamento de eletrodiálise, que pode ser minimizada com alterações de layout da célula e condições de realização dos experimentos, 44,45 sendo que a agitação do sistema pode minimizar esses efeitos. 25,46 Já em relação aos experimentos em fluxo, houve a recuperação de 306,73 mg L -1 de íons nitrogenados, e 223,6 mg L -1 de íons cromo hexavalente. Verifica-se que para esta condição experimental o fenô-meno de precipitação é minimizado, bem como a decantação.…”

“…Estes resultados superiores em termos de eficiência de remoção podem estar relacionados com o incremento de íons transportados devido à turbulência local na interface solução/membrana. 25 …”

“…The principal disadvantage of ED is the inability to remove simultaneously the non-ionic substances (eg organic compounds) from the dilute stream, what can be done with the use of reverse osmosis. The effectiveness of electrodialysis (ED) for (a) the separation of Cu and Fe and (b) water recovery from solutions analogous to those found in copper electrowinning operations, has been studied by Cifuentes et al [52]. A five-compartment ED cell with recirculation of the electrolytes and a synthetic solution, similar to a copper electrowinning electrolyte, were used.…”
