Abstract:
Das erfindungsgemäße Verfahren sieht vor, anhand von Verbrauchsprofilen der Verbraucher und Füllstandsprofilen der Behälter in einem betrachteten Wasserversorgungsnetz die Zeitdauern (Formel I) zu ermitteln, bis nach Ausfall des Wassernachschubs für einen oder mehrere Behälter oder nach sprunghafter Erhöhung des Verbrauchs ein Behälter leerläuft. Die jeweils kürzesten ermittelten Zeitdauern (Formel II) stellen ein Maß für die Versorgungssicherheit zum Zeitpunkt des jeweiligen Ereignisses (Ausfall des Wassernachschubs, erhöhter Verbrauch) dar.

Abstract:
A computer apparatus runs a hydraulic model using real-time or near-real-time data from an Automated or Advanced Metering Infrastructure (AMI), to improve model accuracy, particularly by obtaining more accurate, higher-resolution water demand values for service nodes in the model. Improving the accuracy of water demand calculation for the service nodes in the model stems from an improved technique that more accurately determines which consumption points in the water distribution system should be associated with each service node and from the use of real-time or near-real-time consumption data. The computer apparatus uses the water demand values to improve the accuracy and resolution of its water flow and pressure estimates. In turn, the improved flow and pressure estimation provides for more accurate control, e.g., pumping or valve control, flushing control or scheduling, leak detection, step testing, etc.
Abstract:
A geothermal energy installation and system (10), in which the field of potable water (12) is utilized by a secondary conduit system (32) to route potable water (12) from an inlet (18) in the user's line (16) coming from the potable water field (12) but upstream of the user's meter (24), through the heat exchanger equipment (30) of a user, and back to the field (12) at a point upstream of the final treatment processing stage of the field. Thus, the thermal energy of the water of the field (12) is utilized without adding the cost of the volume of potable water used (27) by the user, and is re-processed if somehow contaminated in the secondary conduit systems (32); and although the secondary conduit system (32) delivers water back to the field (14) at a changed temperature, depending upon the heat exchanger (30) effect, the relatively large volume of water of the potable water field (12) assures that the returned water does not even substantially alter the temperature of the potable water field (12).

Furthermore, according to another aspect of the present invention, there is disclosed an apparatus 1 for water supply and sanitary purposes, where the apparatus 1 comprises a light unit 3 intended for neutralisation of organisms in said water flow, said the light unit 3 being an UV LED unit.1
Abstract:
Apparatus for a network of conduits distributing liquid that is coupled to a supply of liquid and to a network. At least one sensor is coupled in fluid communication with the network and derives a level of demand of liquid from the network. At least one valve is coupled in fluid communication with the supply of liquid and with the network to control the flow of liquid to the network. A control unit is coupled to the sensor and to the valve, to command operation of the valve, and in absence of demand of liquid, to maintain a reduced pressure of liquid in the network relative to the supply pressure. The apparatus has a reservoir that accumulates liquid and to releases liquid in response to, respectively, a rise and a drop of pressure of liquid in the network, whereby reduction of pressure by release of liquid is avoided.
Abstract:
Procédé de contrôle, en temps réel, de la qualité de l'eau d'un réseau de distribution d'eau potable comportant, d'une part, sur des branchements pour consommateurs, des compteurs de consommation (9a) équipés de dispositifs de télérelevé, et, d'autre part, des analyseurs en ligne (10a) répartis en des points de surveillance sur le réseau pour la mesure d'au moins un paramètre de qualité de l'eau. Les compteurs (9a) sont équipés de dispositifs de télérelève et les données de consommation des différents compteurs (9a), ainsi que les mesures des analyseurs (10a) sont transmises à une unité de calcul (A) programmée avec un modèle cinétique de décroissance du paramètre de qualité considéré; l'unité de calcul (A) met à jour en permanence le modèle hydraulique selon les données de consommation reçues des compteurs (9a,9b...); l'unité de calcul (A) établit des valeurs estimées attendues de la concentration dans l'eau du paramètre considéré aux différents points de surveillance du réseau, et un système de pré-alerte (w) effectue une comparaison entre les valeurs estimées du paramètre de qualité et les valeurs mesurées en différents points du réseau, une alerte étant déclenchée lorsque l'écart entre la valeur mesurée et la valeur estimée attendue dépasse un seuil prédéterminé.
