摘要：
The invention relates to a process for decreasing the contents of iron and manganese in ground water or surface water flowing through an aquifer or through a basin or a filter containing naturally occurring filter material. Water containing oxygen or oxygen-releasing substances is introduced intermittently through a number of injection wells or injection pipes (1-9) arranged around an extraction well or extraction pipe (10) for purified water. During each introduction of oxygen-containing water said water is fed to only some of said injection Wells or pipes (1-9) and simultaneous- . ly water is drawn from nearby, adjacent or intervening injection wells or pipes (1-9).
