Treatment of complexed copper in waste water

27/2/2019, · A. Copper responds very well to ferrous sulfide. It is generated in situ by adding a little ferrous sulfate (about 1 - 2 pounds per 1000 gallons of wastewater) at pH 4 or thereabouts, raising the pH to 9 with sodium hydroxide, and dosing the waste with sodium sulfide. This should be used sparingly - about a pound per 1000 gallons of wastewater.
