What are heavy metals?

Heavy metals are particulate and soluble contaminant. The most common heavy metal contaminants that enter industrial and municipal wastewater from manufacturing processes and/or process additives include copper (Cu), silver (Ag), cadmium (Cd), cobalt (Co), chromium (Cr), zinc (Zn), mercury (Hg), manganese (Mn), nickel (Ni), tin (Sn), gold (Au), iron (Fe), and vanadium (V). The metals of concern will vary from plant to plant.

What are the effects of heavy metals on the environment?

Metals in waste streams don't naturally degrade and are toxic to aquatic life, even at low concentrations. The effects of heavy metals on the environment include potential contamination from particulate metals as suspended solids entering receiving streams, as well as being toxic to aquatic organisms in the soluble form.

How are heavy metals removed from water and wastewater?

Heavy metals are removed from water and wastewater by chemical precipitation followed by a solids separation step, which can include clarification, flotation and/or filtration.
