Wastewater treatment for metals
The sulfide results in a lower solubility than hydroxide precipitation alone. In some cases, neither ... are organic compounds that hold metals in solutions at high pH. Hydroxide precipitation depends on the insoluble metal hydroxide forming and the chelating agent prevents this. Some sulfides and strong ...

2.8.3 Common Treatment Technologies for Inorganics in
Ground Water, Surface Water, and Leachate
Typical removal of metals employs precipitation with hydroxides, carbonates, or sulfides. Hydroxide precipitation with lime or sodium hydroxide is the most common choice. Generally, ... 4.5, sulfide precipitation can achieve the EPA-recommended standard for potable water. Sulfide precipitation, however, can be considerably more expensive than hydroxide precipitation, as a result ...
