Abstract
The development of new strategies to remove ionic metals from wastewater has been became in a global need. To design closed circuits that avoid release these compounds to the environment, from the environmental and production point of view, become each time more necessary. In this way, different kind of methods to remove metals are utilized, such as are the membranes systems. In this context, Electrodialysis and Electrodeionization are electrochemical process of membranes, which them have the capability to remove ionic species. This is why, both methods are available to be use as treatment of water polluted with heavy metals, without to generate wastes. In this way, the aim of the present work is to show the results of the use of these technologies applied to the remove of Trivalent Chromium from synthetic solutions, and evaluate their performance. Commercial membranes and resins were tested during the respective process in order to get advantages or disadvantages, when is used 100 or 1000 ppm Cr (III) solutions. The results presents some advantages for ED using bigger concentrations, meanwhile EDI is much better working low concentrations, spending less energy.
