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.
