The formation of halogenated hydrocarbons is considered a major drawback in disinfection of waste water using chlorine. The behavior of ozone as an alternative treatment agent was studied by monitoring the generation or destruction of twenty-one volatile halogenated organic compounds that were either proved or suspected products during the chlorination of waste water. The results demonstrated that ozone is preferable to chlorine. While chlorination most of the time resulted in an increase of halogenated compound concentration, ozonation usually diminished the levels of these compounds. Only in one case did ozonation give moderately high production of halogenated organics (tetrachloroethylene). It was found that the behaviors of these oxidizing agents were considerably different in waste water than in carbon filtered water; the chemical reactivities of oxidizing agents may be reinforced in the waste water by certain inorganic species such as trivalent iron.
