In decorative or functional galvanizing, a metallic coating is applied to an objects’ surface through an electrochemical process. Galvanization is common for wear protection, but also used to manufacture CDs and DVDs. Galvanization results in wastewater and sludge contaminated with oil, grease, chemicals, metals and material residues.
