Phénomènes de transfert dans un procédé d'électrodéionisation de solutions diluées de cuivre : étude expérimentale et modélisation

Abstract : The work is devoted to comprehension and modeling, as weIl experimental as numerical, of the electro-deionization on three strong-acid cations exchangers on a pilot at lab scale for copper removal from dilute synthetic solutions of copper simulating rinsing waters issued from galvanic processes. Electrodeionization is a hybrid process based on a combination of ion exchange and electrodialysis. Before apprehending this hybrid process the ~echanisms of transport of ions in the resin bed and the membrane using a kinetic model of J. Janssen et al. were studied. The operating conditions to implement to optimize the electrodeionization were sought and made it possible to establish the feasibility of this process. The effects of the height of the bed, the cross-linking degree, the density of current and the copper concentration in feed solution were studied. From the experimental results of the electrodeionization, the specific conductivity of the bed was estimated using a model which consists in calculation of the potential fields in the cell by integration of the Laplace equation using FEMLAB TM software.
