Zusammenfassung:	A method of purifying a produced water comprising contacting a produced water stream with a composition comprising a (i) a chelant; (ii) an oxidizing agent; and (iii) a surfactant under conditions suitable for the formation of a purified produced water. A composition for purifying produced water comprising (i) a biochelant in an amount of from about 1 wt. % to about 10 wt. %: (ii) an oxidizing agent in an amount of from about 3 wt. % to about 50 wt. %; (iii) a surfactant in an amount of from about 0.1 wt. % to about 70 wt. % wherein the weight percentage is based on the total weight of the composition; and (iv) a solvent.
