摘要

The procedure for in-situ cleaning of contaminated ground water flow, comprises carrying out direct gas injection of a reactive gas mixture from compressed air and oxygen with gas injection elements into the porous solid matrix of a contaminated water flow. A reactive gas wall and a reactive outlet stream are developed and operated as flow reactors connected in rows. The compressed air and oxygen are produced continuously in a fully automatic procedure in a unit for the air separation directly on the spot. An automatic additional system is covered by a system with a liquid oxygen container.

A reactive gas wall and a reactive outlet stream are developed and operated as flow reactors connected in rows. The compressed air and oxygen are produced continuously in a fully automatic procedure in a unit for the air separation directly on the spot. An automatic additional system is covered by a system with a liquid oxygen container. A membrane plant is used as plant for air decomposition, in which oxygen-rich product flow is used as reactive gas mixture. The oxygen in the plant for the air decomposition based on a vacuum-change in pressure adsorption process is generated with zeolites.
