ED technology has been successfully applied to a number of acid-, alkaline- and cyanide-based plating solutions, but has been most successful in recovering chromates, tin, nickel, gold and silver. Also, ED has been effective as a “roughing” treatment before reverse osmosis or ion exchange for water with a very high total dissolved solids content.

The separation and reclaiming of various metal ions from ,acid tin, plating ,wastewater, were achieved based on the fact that different metal ions form hydroxide precipitates at different pHs. The influent has a pH of 0.45 and contains Sn 137.3 mg/L, Ni 46.1 mg/L, Fe 11.4 mg/L, and Co 8.6 mg/L. Sn was precipitated as Sn(OH) 2 by adjusting the influent pH to 4.7 with 10% NaOH solution.
