<p>The invention provides a device and a method for the online control of drinking water on human tolerance within a drinking water supply network, comprising at least one drinking water feed point, to which a plurality of lines carrying drinking water are directly or indirectly connected, which lead to local drinking water consumer points. The invention is characterized in that at least one drinking water line section (2) through which drinking water flows is provided within the drinking water supply network, wherein along said section at least one flow volume is provided, which is limited on one side by a semi-permeable limiting means (4) in at least the flow direction, wherein at least one indicator medium (6) having a biological microorganism can be introduced into said volume, wherein the medium be localized by the limiting means (4) within the through flow volume, i.e. is held back by the limiting means (4) within the flow volume against the flow direction, in that a first sensor unit (7, 8) is provided outside of the flow medium for the optical detection of the indicator medium (6), and that an evaluation unit (9) is provided, which is in communication with the sensor unit (7, 8) and in which sensor signals generated by the sensor unit (7, 8) can be analyzed based on at least one evaluation regulation, and which generates a signal if a predefinable decision criterion occurs.</p> |
