The particles can then be aggregated by chemical coagulation and removed by filtration or sedimentation. Chemical precipitation is the most common method for removing dissolved heavy metals from wastewater. It is also among the least expensive technologies and is always combined with chemical coagulation for heavy metal wastewater treatment.Removing Heavy Metals From Wastewater,Metal precipitation is primarily dependent upon two factors: the concentration of the metal, and the pH of the water. Heavy metals are usually present in wastewaters in dilute quantities (1 - 100 mg/L) and at neutral or acidic pH values (< 7.0). Both of these factors are disadvantageous with regard to metalsChemical Treatment of Wastewater Process,Heavy metals can precipitate as metal hydroxides, and anions can precipitate as calcium, iron, or aluminum salts, for example.
