Abstract
An improved method of removing water soluble organics from produced water is disclosed. In the method, a chemical, selected from the group consisting of sodium bisulfite, hydroxylamine hydrochloride, tallow amine, acetic acid, and combinations thereof, is added to the water in an amount sufficient to adjust the pH of the water to about 6.0 to 6.5. Water soluble organics then separate out from the water for easy removal by conventional phase separation techniques.
