Abstract
The invention relates to an optimised bio-electrochemical reactor for treatment of a liquid effluent containing a biodegradable organic pollution. According to the invention, at least one of the anode and cathode compartments of the reactor is a microbial biofilm compartment (12) comprising a multistage current collector immersed in an electrolyte comprising electroactive microorganisms. This current collector comprises at least two stages, each defining a chamber acting as a container for a biocompatible granular support material and allowing the fluid to pass through. The effluent circulates inside the compartment (12) in a direction X crossing the stages of the current collector. In operating mode, the support material (17) is in a fluidised state resulting either from the circulation of the effluent, or from the circulation of a fluidisation gas making it possible to optimise the active surface of the electrode and, consequently, the treatment of the effluent.
The invention relates to a method and system for controlling a membrane separation unit of an aqueous liquid effluent treatment plant comprising a system for injecting at least one chemical compound into the effluent that is to be treated. The method and system make it possible to regulate at least one parameter selected from a quantity of chemical compound(s) to be added and a conversion rate so as to avoid fouling and/or the precipitation of ionic species in the retentate. This regulation uses optimal setpoint values determined on the basis of one or more characteristic parameters of the retentate rather than of the water that is to be treated. By precisely regulating the quantity of chemical compound(s) to be added and/or the conversion rate of the membrane separation unit to an optimal value, it is possible not only to prevent fouling and/or the precipitation of species liable to precipitate but also to minimize operating costs.
A method for incinerating organic matter derived from the treatment of wastewater, or of industrial or agricultural waste, such as sludge and notably treatment plant sludge, is in a fluidized-bed incineration furnace, the furnace including a chamber in the lower part of which there is a bed of particles, preferentially sand, constituting a fluidization zone, in which fluidization zone the organic matter is introduced as fuel whilst air is injected as oxidizer into the bed of sand from a wind box through a fluidization dome surmounting the box. The air passes through passages made in the fluidization dome, and the furnace is configured to treat a nominal value of volume of organic matter to be treated. The method includes a step of adjusting the volume of the fluidization zone as a function of the volume of organic matter to be treated in which, when the volume of organic matter to be treated is lower than the nominal value, the volume of the fluidization zone is reduced from an initial volume to a reduced volume, and the incoming air flow is reduced by closing air passages so only the passages opening into the thus reduced fluidization zone are left active.
The invention relates to a method for determining the remaining capacity of an adsorbent medium in a fluid treatment unit, said treatment involving passing a fluid through an adsorbent medium, said method comprising at least the following steps: • a) measuring the dissolved organic carbon content of the fluid and determining the empty bed contact time on the adsorbent medium; • b) determining at least one target pollutant; • c) determining breakthrough curves for at least two reference pollutants, said breakthrough curves being determined for the dissolved organic carbon content and the empty bed contact time measured in step a); • d) adjusting the breakthrough curves determined in step c) on the basis of the actual operating conditions of the treatment unit; • e) determining the remaining capacity of the adsorbent medium from the breakthrough curves adjusted at the end of step d) for the one or more target pollutants. The invention also relates to a process for treating a fluid in a treatment unit comprising at least one adsorbent medium, said fluid treatment process comprising: i. passing a fluid through at least one adsorbent medium; ii. carrying out the method for determining the remaining capacity of said adsorbent medium, making it possible to determine the remaining capacity of the adsorbent medium; iii. determining the time left until at least some of the adsorbent medium has to be replaced or regenerated again and/or determining the amount of adsorbent medium to be replaced or regenerated on the basis of the remaining capacity of the medium determined in step ii; iv. replacing or regenerating at least some of the adsorbent medium according to the time left and/or the amount of medium determined in step iii. The invention finally also relates to a treatment unit for carrying out said fluid treatment process.

Device, method and computer program product for validating data provided by a rain sensor
A method allowing data delivered by a rain gauge to be validated in real time is provided. The method includes steps of: receiving, in a defined time window, pluviometric data from a gauge and weather data from at least one weather radar; computing a coefficient of gauge/radar similarity between the pluviometric data received from the gauge and the weather data received from the at least one weather radar; comparing the value of the coefficient of obtained gauge/radar similarity to a threshold gauge/radar value; and validating the pluviometric data of the gauge if the value of the coefficient of gauge/radar similarity is higher than or equal to the threshold gauge/radar value.
A method is provided for placing sensors in a fluid distribution network by simulating network operating scenarios; by determining candidate sets of sensor positions; by determining the measurements of each sensor in each scenario, and the detection of associated anomalies; by attributing a score to each candidate set of sensor positions, representing the capacity of the sensors placed in the positions of the set to accomplish a mission. Finally, the candidate sets are modified using so-called genetic algorithms until a stop criterion is validated. The genetic algorithms can for example consist in crossing over or mutating candidate sets.
