GALVANIC
Wastewater treatment during production and processing in the electroplating industry.
In the electroplating industry, the PRO-PUR Series are used to treat wastewater generated during production processes. This water contains a variety of chemical and organic substances that must be removed before the water is discharged or reused. Here is a detailed analysis:
Substances Treated with PRO-PUR in Electroplating
Heavy Metals:
Chromium (Cr): Often present in the form of trivalent chromium (Cr(III)), which is highly toxic.
Nickel (Ni): Used in various plating processes.
Copper (Cu): Present in electroplating baths.
Zinc (Zn): Used in galvanising.
Lead (Pb): Sometimes present as a contaminant.
Cadmium (Cd): Less common but highly toxic.
Chemical Substances:
Cyanides: Used in some plating baths.
Acids and Alkalis: Sulphuric, hydrochloric and nitric acids, as well as alkaline solutions such as caustic soda.
Organic Solvents: Residues of solvents used in cleaning metals.
Suspended Solids:
Metallic Particulates: Small particles of metal suspended in the water.
Metal Oxides and Hydroxides: Formed during neutralisation processes.
Other Contaminants:
Surfactants: From pre-treatment processes
Oils and Fats: From processing and cleaning.
Dyes and Additives: Used in some finishing processes.
