Heavy Metal Precipitation
Removing Dissolved Metals by Precipitation and Settling
Plate settlers clarify precipitated metal hydroxides from metal finishing and industrial effluent, achieving low dissolved-metal discharge.
Heavy Metal Precipitation
Heavy metals such as chromium, nickel, zinc, copper, and lead must be removed from industrial effluent to meet strict discharge limits. pH adjustment precipitates dissolved metals as insoluble hydroxides.
These metal-hydroxide flocs are light and fine, requiring efficient clarification. Plate settlers capture them at high loading rates, delivering low-metal effluent and a concentrated metal sludge.
The process is central to metal finishing, electroplating, and many industrial wastewater treatment schemes, and benefits from robust stainless-steel construction.
