    Abstract: A system for measuring water flows in a sub-network of a water distribution network is provided. The system includes a plurality of sensors, for example pressure sensors, on the network. The system further comprises communication links between the sensor and one a computing device, and a measurement acquisition system. The computing device is configured to retrieve values of measurements, directly or through the measurement acquisition system; use values of measurements to determine values of control variables of a model of the water distribution network which minimize residue values between measurements values and predicted physical values on the network; then use the model parameter with the values of control variables to calculate water flows at the boundaries of the sub-network.

    Abstract: A device for reading and transmitting measured temperature values for a device for monitoring a fluid flowing inside a pipe is disclosed. The device may include a temperature sensor configured to provide temperature values in accordance with time and a processing module, as well as a transmitter connected to the temperature sensor and configured to transmit signals that represent said temperature values, and a receiver configured to receive said signals. The temperature sensor may be mounted in a position that is close to the pipe. In addition, the processing module may be configured to assess a temperature variation speed, and of producing a signal to alert of the transformation of the fluid to the solid phase, when the temperature variation speed decreases over a given time interval.

    Abstract: Disclosed are water treatment processes enabling cations and anions to be extracted from an aqueous effluent by contacting the aqueous effluents with a hydrophobic liquid phase, also including at least one step of contacting the effluent with a hydrophobic solid membrane, in order to remove the residual hydrophobic liquid membrane in the effluent treated by coalescence on the hydrophobic solid membrane. The processes include seawater desalination processes. Also disclosed is a desalination module as well as its facility therefor, including at least one coalescer.

    Abstract: A hydraulic model of the network is used that describes the structural data and the laws governing the distributed flows. The model is fed with operational data relative to primary input parameters and, using the model, theoretical values are obtained for primary output parameters. The theoretical values are compared with measured values. In case of a significant deviation, the corresponding primary output parameter becomes a secondary input parameter in an inverse model including new secondary output parameters, which are added relative to the direct model and which correspond to primary input parameters. The secondary output parameters are, by priority, those to which the primary output parameter exhibiting the abnormal value is particularly sensitive. If necessary, the method is implemented iteratively by progressively restricting the number of the secondary output parameters.

    Abstract: Disclosed is a method for detecting anomalies in a distribution network equipped with sensors. The steps are: acquiring for each sensor a time series of physical measurements separated by time intervals; defining time windows each corresponding to a plurality of successive time intervals; extracting operational characteristics of each time series in each time window; forming, for each time window, at least one current vector having for coordinates the operational characteristics, structural data relating to the network and situational characteristics specific to the time window; comparing the current vector with preceding vectors corresponding to preceding time windows and the situational characteristics and structural data of which are similar to those of the current vector; and signalling an anomaly in cases where the current vector is significantly dissimilar to the preceding vectors.
