Recovery of Metals from Sludges and Watsewaters. Project ...

The principal area of application of elec- trodialysis is the recovery of metals from electroplating bath rinse waters. In many cases, the wastewater must be filtered before it is fed through the elec- trolytic reactor. Adjustment of pH is a nec- essary pretreatment measure because the waste pH affects metal speciation.

These are precipitated as hydroxides, which form a sludge. For, recovering, the metals, the sludge is dissolved in sulfuric acid to produce metal sulfate solutions. The metals are then, recovered, by electrolysis. The relatively simple principle has been applied for the, recovery, of nickel from an, electroplating waste, liquid (Solozabal, et al., 1999).
