    摘要: The invention refers to a device for creating in an aquifer an oxidation and precipitation zone or a reduction zone between a number of injection wells arranged around one or more extraction wells for purified water, said injection wells each comprising an outer water-pervious tube (1). For preventing such a device from being clogged the invention suggests that at the upper end of the outer tube (1) is mounted a circulation vessel (2) from which extends downwardly within the outer tube (1) a first conduit (3), ending at the height of the upper portion of the aquifer and provided with a pressure inlet means (5) so as to form an upper ejector, and a second conduit (4), which at its lower end supports an externally sealingly mounted balloon body (7), which is inflatable into sealing engagement with the inner surface of the outer tube (1), said second conduit closely above said body carrying a pressure inlet means (6), so as to form a second ejector.

    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).

    摘要: The invention relates to a process for decreasing the content of nitrate in ground water, artificial ground water, that is infiltrated surface water, or sarface water flowing through an aquifer or through a basin or a filter containing naturally occurring filter material. Water containing denitrification organisms and or substrate therefore is introduced intermitterially through a number of injection wells or injection pipes arranged around the or more extraction wells or extraction pipes for purified water. During each introduction of water containing denitrification organisms and/or substrate therfore said water is fed to only some of said injection welle or pipes and simultaneously water is drawn from nearby, adjacent or intervening injection wells or pipes or the purpose of creating a denitrification zone at a distance suficiently far from the extraction well or extraction pipe.

    摘要: A utility water distribution system comprising a trunk water main (1) to which has been connected a water reservoir (2). Large and medium-size water supply works have elevated water reservoirs, such as water towers or feetless tanks mounted at high altitude, which involve high initial cost. The water reservoir (2) of the invention consists of a pipe installed in the ground and closed at one end and which has been connected to the trunk water main (1) by an automatically operating shut-off valve (5), for instance one provided with a float (4).

    摘要: Wastewater containing nitrate and/or nitrite is purified by passing said water, in a first stage, under reducing conditions through a basin or a filter containing naturally occurring filter material. The reduced water is then oxygenated in a second stage and kept in a basin until the oxidation processes are completed.
