A three-compartment membrane cell was used to investigate the electrohydrolysis of sodium sulphate for the regeneration of acid and base. The membranes used were Pall R1010 cation exchange and Pall R 1030 anion exchange. The effect of flow rate, current density and initial salt concentration on the performance of the cell (current efficiencies, transport properties and product concentrations) are reported. The performance of this configuration is compared to a two-compartment cell in terms of current efficiencies, power consumption and product concentrations, The three-compartment configuration has the advantage of producing high purity acid and base, but at a greater operating cost.
