Abstract: In the field of wastewater or effluent treatment, a method for treating wastewater includes a first step of treating carbon contained in the wastewater by means of oxygen, a second step of treating the nitrogen contained in the treated water at the end of the first step, a third step of determining a ratio between a concentration of carbon and a concentration of nitrogen in the water at the end of the first step, a fourth step of controlling the supply of oxygen necessary for the first step as a function of a difference between the determination carried out in the third step and a strictly positive setpoint of concentration ratio. A device implementing the method is also provided.

Abstract: A computer-implemented method, computer program, and device for evaluating timed-based probabilities of failure of sections of a pipe network are provided. To do so, the pipe sections are clustered into classes based on structural and environmental parameters; within each class a sample of pipe sections are selected to be inspected. The scores that are obtained through the inspection are used to train a model of pipe conditions of pipes in a class, in order to estimate the pipe conditions of pipes that have not been inspected. The pipe conditions are used to parameterize a predictive model of pipe failures.

Abstract: Disclosed is a system and a method for classifying articles in a flow of articles to be separated, the flow of articles to be separated being installed on a conveying device, including: —an image acquisition member installed so as to be able to acquire at least one image of a portion of the flow of articles to be separated; —a first overhanging light source, which emits in the visible spectrum and illuminates the portion of the flow of articles to be separated, the at least one image of which is acquired by the image acquisition member; a classification member capable of classifying the articles of the portion of the flow of articles to be separated according to the acquired image; and at least one second light source, of a different nature than the first light source, allowing additional visual information to appear on the acquired image.

Abstract: The present disclosure relates to the field of odor treatment. In particular, the disclosure relates to a method for managing a waste gas treatment device. The method includes the following steps: a step of taking into account gaseous pollutant concentration predictions at at least one point in a predefined geographical area; a step of comparing each predicted gaseous pollutant concentration at the at least one point of the predefined geographical area with a gaseous pollutant concentration reference value; a step of transmitting, to a control unit of a bypass air line of a waste gas treatment unit, a command to at least partially open the bypass air line when the result of the comparison indicates that at least one predicted gaseous pollutant concentration value is less than a gaseous pollutant concentration reference value.

Abstract: A bioelectrochemical reactor (1) has an anode chamber (11) having at least two bioanodes (12, 13), and an anodic electrolyte (14) with an anodic electroactive microorganisms,—a cathode chamber (21) with at least one biocathode (22), and a cathodic electrolyte (24) with a cathodic electroactive microorganisms. The anode chamber (11) is separated from the cathode chamber (21) by, running from the anode chamber to the cathode chamber, a cation exchange membrane (31) and an anion exchange membrane (32). The cation and anion exchange membranes are separated from each other by an inter-membrane chamber (30), and means for applying a potential difference between the interconnected bioanodes and the biocathode/biocathodes. The bioanodes and biocathode/biocathodes have active surfaces such that the total active surface of the biocathode/biocathodes (22) is greater than the total active surface of the two bioanodes (12, 13). The arrangement includes a method for regenerating the activity of the bioanodes of the reactor and to the use of said reactor for the electrosynthesis of organic acids and/or alcohols from organic waste.

Abstract: A method for determining an optimal dose of coagulant for raw water includes a step of determining a value, for the raw water, of a first organic parameter; a step of determining a value, for the raw water, of a second mineral parameter; a step of determining a class of water for the raw water, characterized by the value of the first organic parameter and the value of the second mineral parameter; a step of determining a value, for the raw water, of a third organic parameter; a step of defining a target value, for the clarified water, of the third organic parameter; a step of selecting a function between the third organic parameter and an added dose of coagulant, said function being selected for the class of water and for the value, for the raw water, of the third organic parameter; a step of using the function to determine a first dose of coagulant in order to reach the target value.
