METHOD AND DEVICE FOR IN-SITU CLEANING OF CONTAMINATED GROUNDWATER FLOWS

摘要

Process for the in-situ cleaning of contaminated groundwater streams (3) comprises operating a direct gas injection with fewer gas injection elements than flow reactors connected in series. An independent claim is also included for an arrangement for carrying out the process. Preferred Features: A reactive gas wall (4) is structured so that a gas mixture (1) is introduced into a porous solid matrix corresponding to the gas/hydro-geological positional ratios, distributed and stored. Air is used as a carrier of the gas mixture to introduce and distribute the reactive gases.
