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: Disclosed is a process for treating a stale gas, involving the following steps: circulation of the stale gas in a gas/liquid contactor, called a contactor, and then circulation of the stale gas in a filter unit, called a filter unit, the process involving, in the contactor, placing a circulating liquid in contact with the stale gas, the circulating liquid having a temperature of between 2 and 15° C., preferably between 5 and 10° C., and also to a treatment unit for performing the process including a gas/liquid contactor and a filter unit.

Abstract: Disclosed is a piston press of the type used in the field of the dehydration of products to be dehydrated such as sludge from a purification plant. More particularly, it relates to a piston press including a pressing chamber supplied with sludge and able to manage air streams that it generates, and to a method for using such a press. In a preferred mode of embodiment, the piston press includes a pipeline having a water removal branch and arranged so as to remove water extracted during a sludge-pressing operation, and an air circulation branch that can channel the volumes of air circulating in the press during the operation thereof, so as to direct the vitiated air, i.e. air that has been brought into contact with the sludge during the implementation of the press, towards a deodorization system.

Abstract: Disclosed is a system for determining a level of nuisance generated by an industrial installation, including at least one aerial drone, the aerial drone being controllable to move to a measurement point above the industrial installation, and to determine, at the measurement point, by way of at least one sensor fitted to the aerial drone, at least one level of a quantity generating the nuisance, the system furthermore including a treatment unit configured to determine the nuisance level on the basis of the level of the sensed quantity
