Removing Heavy Metals From Wastewaterthe water so that the metals will form insoluble precipitates. Once the metals precipitate and form solids, they can then easily be removed, and the water, now with low metal concentrations, can be discharged. Metal precipitation is primarily dependent upon two factors: the concentration of the metal, and the pH of the water.

AntimonyAntimony in the air can cause lung effects in workers and laboratory animals. Antimony can also cause heart problems. It can damage the heart muscle and cause changes in electrocardiogram (EKG) readings. High levels of antimony in drinking water can cause vomiting and abdominal pain. These effects have also been reported by antimony workers.
