The aim was to predict separation Received in revised form 21 February 2009 percent (SP) of zinc ions as a function of concentration, temperature, flow rate and voltage. At first, a Accepted 1 March 2009 Sugeno type FL inference system was applied to model zinc ions separation from wastewater using ED. FL modeling results showed that there is an excellent agreement between the experimental data and the Keywords: predicted values, with mean squared relative error (MSRE) of less than 0.01. Then, the results of a previ- Fuzzy logic ously developed MM were presented. The MM related SP to hydrodynamic dimension of the ED cell and Electrodialysis Mathematical
