Abstract
Technologies to recover copper from the rinsewater of acid copper plating are well known. However, specific problems must be overcome in order to design an effective recovery process. These specific problems for acid copper plating include the following: Bath volume growth, copper concentration growth and acid concentration growth will occur if the recovered chemicals are returned to the plating bath; The rinsewater in the final rinse stage must have a low concentration of copper and acid; The recovery unit must provide a return on investment over the existing wastewater pretreatment plant.
