Abstract: A system for disinfecting and removing biological material from water to be injected into an injection well in a water body is described; the system includes: at least one apparatus for the gravitational precipitation of particles from water, which is connected, in terms of fluid, to a source of untreated water and to the injection well; and an apparatus for the addition of an oxidant for the disinfection of water, which is connected in terms of fluid to the apparatus for the gravitational precipitation of particles, a source of untreated water and to the injection well such that the apparatus for the gravitational precipitation of particles is positioned downstream relative to the apparatus for the addition of an oxidant for disinfection. The disclosure also relates to a method for disinfecting and removal of biological material from injection water.

Abstract: Technical system and method for online measuring and monitoring of the particle content in an injection water flow (6?) in an underwater line (8). The system comprises a data gathering means, a data communication link (48) and a data receiving means comprising an image analysis apparatus (2) provided with: a water sample line (18) for throughput of a partial flow (6?) of the injection water flow (6?); a means of conveyance (24) connected to the water sample line (18) for transport of the partial flow (6?); a light-transparent flow portion (18?) disposed along the water sample line (18); a camera (26) at the flow portion (18?); at least one light source (30, 32) for emission of light (34) via the flow portion (18?) and into the camera (26); an electronic control means (36) for (a) control of the image recording of the camera (26); (b) reception of image material from the camera (26); and (c) transmission of the image material to the data receiving means; and at least one energy supply.

Abstract: Technical system (2; 2?), method and uses for dosing of at least one liquid treatment means (12) into injection water (16) to an injection well (22), wherein the technical system (2; 2?) comprises: —an underwater line (14; 14?) for transport of the injection water (16) from a shipment site (20; 48) for the injection water (16); and —at least one liquid-tight storage unit (10) containing the at least one liquid treatment means (12). The distinctive characteristic is that the at least one storage unit (10) is structured as a volumetrically flexible unit; —wherein said storage unit (10) is placed under water (6); and —wherein said storage unit (10) is connected, in a flow-communicating manner, to the underwater line (14; 14?) for dosing of liquid treatment means (12) into the injection water (16) to the injection well (22).
