Heavy metal precipitants

Heavy metal precipitants

Complexing agents are indispensable in modern surface treatment. Their applications are very versatile so that almost all industrial wastewater mainly contains organic complexing agents. In wastewater treatment plants, complexing agents interfere with the hydroxide precipitation of metals and can therefore lead to an exceeding of legal limits. Through the use of liquid heavy metal precipitants, heavy metals can be removed from complexed heavy metal compounds – mostly sulfidic. They can be precipitated as sparingly soluble compounds and then filtered.
