Abstract

The present invention refers to a process for creating in an aquifer an oxida-tion and precipitation zone (or a reduction zone) between a number of injection wells arranged around one or more extraction wells for purified water. The zone de-sired is created intermittently between each pair of adjacent injection wells by (i) in-troducing oxygen, oxygen-containing gas or an oxygen-releasing substance (or an oxygen-consuming substance) into the water in both wells and (ii) pumping the wa-ter in one well from below upwards while pumping the water in the other well from above downwards, whereby a circulation circuit is formed in the aquifer between the webs. A device for carrying out said process comprises an outer tube (1), sealing means (2), an inner tube member (3), a transversal wall (4) with a central opening, an elongation tube (5), an inner flow pipe (6) and conduits (7, 8) for supply of air.
