Correlation of ionic transfer rate in electrodialysis under limiting current density conditions

The effects of Reynolds number, Schmidt number, and shape factor of the electrodialysis cell on the Nusselt number in ion exchange membrane electrodialysis have been investigated. An empirical correlation, ( Nu)' exp=1.793 Re 0.340 Sc 0.329( d e/L ) 0.301, is obtained at limiting current densit...

Summary:The effects of Reynolds number, Schmidt number, and shape factor of the electrodialysis cell on the Nusselt number in ion exchange membrane electrodialysis have been investigated. An empirical correlation, ( Nu)' exp=1.793 Re 0.340 Sc 0.329( d e/L ) 0.301, is obtained at limiting current density for solutions of five electrolytes, CH 3COONa, NaCl, CuSO 4, NiSO 4, and H 2SO 4, in a planar electrodialysis channel. The correlation is in good agreement with the theoretical performance equation.
