The effect of pH and temperature (theta) on the overall performance indicators (i.e., solute recovery, rho, and Faraday, eta, efficiencies; specific energy consumption, epsilon, solute, J(S), and water, J(W), fluxes) of batch electrodialytic recovery of citric acid from model solutions was assessed at different values of feed solute concentration (c(Sf)) and electric current density (j). Regardless of the initial feed concentration used, rho and J(S) were found to be independent of theta; eta and J(W) exhibited a positive trend with respect to theta, while epsilon a negative one. Ar the maximum temperature tested (33 degrees C), as the pH of the feed solution was varied from 3 to 7, rho increased from 0.90 +/- 0.08 to 0.97 +/- 0.02, eta grew from 0.09 +/- 0.02 to 0.50 +/-. 0.01, J(S) practically doubled, epsilon reduced about 8 times, but J(W) increased from 3 to 4 times. So, the optimal conditions for this technique are to be determined by balancing the savings in the investment and maintenance costs against the energy costs.
