    Abstract: A process for monitoring the concentration of organic compounds in a fluid of a network, the fluid includes volatile organic compounds, comprising the following steps: first step of on-line measurement of the concentration of each of the organic compounds of the organic compounds in the fluid by an analyzer, second step of comparing the concentration of each of the organic compounds measured by the analyzer with a predefined threshold value for each of the organic compounds, third step of reducing the concentration of at least one organic compound if the concentration of the at least one organic compound measured by the analyzer is greater than the corresponding predefined threshold value. A device for monitoring the concentration of organic compounds is also provided.

    Abstract: Disclosed is a method for dynamically controlling a fluidic network with a supervising module, the method including: an operation-forecasting step that generates a forecast datum relating to operation of the fluidic network; a step of selecting a control strategy for the fluidic network on the basis of a metrological datum and/or a meteorological datum and/or the forecast datum; a step of generating setpoints intended for an actuator of a unit for regulating the fluidic network, on the basis of the selected control strategy, the metrological datum or the meteorological datum or the forecast datum; and transmitting the regulation setpoint to the actuator.

    Abstract: A process for monitoring the concentration of bacteria in the water of a water distribution network, wherein the process includes the following steps: measuring the concentration of bacteria in the water by means of a first sensor positioned at a first location in the water distribution network, determining a variable instantaneous value of the expected concentration of bacteria in the water at the first location as a function of a parameter characteristic of the water, comparing the concentration of bacteria in the water measured by the first sensor to the variable instantaneous value, corrective action acting on the concentration of bacteria in the water if the concentration of bacteria in the water measured by the first sensor exeeds the variable instantaneous value. A device for monitoring the concentration of bacteria in the water of a water distribution network is also provided.

    Abstract: Disclosed is a method for detecting domestic hot water use by a sanitary fitting during an observation period by analysing data relative to volumes of water passing through a water meter, the method including: receiving a first item of data, noted VΔ1, representing the maximum volume of fluid measured over a predetermined period, preferably equal to 5 minutes; receiving a second item of data, noted VΔ2, representing the maximum volume of fluid measured by the meter during another predetermined period, preferably equal to 15 minutes; and detecting that domestic hot water has been used when VΔ1>15 litres and VΔ2≥20 litres.

    Abstract: A method for treating a fluid, notably liquid, in particular water, containing pollutants, is performed by passing a downward stream of fluid through a bed of activated carbon in the form of grains in a treatment station. The method includes a partial renewal of activated carbon including at least one injection of activated carbon and at least one extraction of activated carbon. An installation suitable for implementation of the fluid treatment method is also disclosed.
