Abstract: A method for controlling for PFAS removal from a liquid effluent by a control system (100), the control system including a PFAS treatment unit (10) dedicated to the treatment of perfluoroalkyls and polyfluoroalkyl substances PFAS including at least one treatment stage optionally chosen from a PFAS treatment stage, a short chain PFAS treatment stage and a long chain PFAS treatment stage. The method allows activating the PFAS treatment unit only when PFAS, in particular specific PFAS, are detected into the liquid effluent to treat. A control system (100) to implement the method is also disclosed.

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.
