Abstract: In a preferred embodiment, plating chemicals are recovered from contaminated rinse water using an electrodialysis recovery unit immersed directly in an electroplating bath between a cathode intended to be plated and an anode. Electrodialysis is driven parasitically by the electroplating currents, thereby eliminating the cost of additional equipment dedicated solely for electrodialysis. The unit is sized and positioned so that only a relatively minor portion of the total plating current is employed for electrodialysis, thereby permitting a sufficiently high current density at the cathode to electrodeposit a dense, commercially acceptable metal plate.
