Abstract (en)
[origin: DE19807155A1] The invention relates to a method for the oxidative treatment of water containing organic compounds, according to which the water is mixed (1) with a reagent containing hydrogen peroxide and iron or titanium ions in solution. Said method is characterized in that the mixture is subjected to a membrane separation stage (4), in which a permeate constituting the treated waste water (6) is extracted from the mixture.
