  • METHOD FOR REMOVING POLYFLUORINATED ORGANIC COMPOUNDS FROM WATER BY MEANS OF AN ADSORBENT AND REGENERATION OF THE LATTER
    Publication number: 20210346862
    Abstract: The invention relates to a method for removing polyfluorinated organic compounds from water by means of an adsorbent and to the regeneration of the latter. According to the invention, at least one zeolite is used as an adsorbent, which is brought into contact with the water and is then regenerated by wet-chemical oxidation, wherein the oxidation is carried out by means of UV irradiation and/or at a pH in the range from pH 2.5-7.5.

  • Method and device for decontaminating waters which are loaded with organic halogen compounds (halogenated hydrocarbons)
    Patent number: 7252771
    Abstract: The invention relates to a process and a device for decontaminating waters, especially groundwaters, which are heavily and complexly polluted with organic halogen compounds (HHC), in which process the contaminated waters are pre-treated in order to convert low-volatility HHC into more readily volatile components, the halogenated hydrocarbons are subsequently transferred from the aqueous phase to the gaseous phase where complete conversion into halogen-free compounds takes place at elevated temperature by means of catalytic reductive dehalogenation.
