Electrochemical processes can provide valuable contributions to the protection of the environment through implementation of effluent treatment and production-integrated processes for the minimization of waste and toxic compounds. The performance of a novel pilot scale, fixed bed flow-through cell, consisting of stainless steel tubes bundle cathode, in the removal of cadmium was investigated in the batch re-circulation mode; utilizing the potential results obtained from rotating disc electrode experiments in batch mode. The studied electrochemical reaction was the cathodic reduction of Cd2+ using 0.5 M sodium sulphate as supporting electrolyte. The analyzed parameters were different electrolyte pH, different initial Cd2+ concentrations, and different Reynolds numbers. The tubes bundle consisted of 920 tubes of 0.6 cm outer diameters. The overall empirical mass transfer correlation was found to be: Sh = 0.51 Re0.859 Sc1/3 for 5 < Re < 20 and Sc = 649. Experimental results, analysis and correlations showed good performance of the cell and proved its adequacy in the removal of Cd2+ from simulated effluents.
