Method For Calculating An Operating Parameter Of A Digester In The Presence Of At Least One Inhibitor

Abstract: The invention relates to a method (1) for calculating an operating parameter of a digester suitable for producing a digestate and biogas, containing methane, the method comprising the following steps: - a step (2) of defining a concentration range of an input of the digester and an operating temperature range of the operation; - a step (3) of preliminarily estimating an intermediate concentration; - a step (4) of determining the pH within the digester; - a step (5) of estimating a concentration of at least one inhibitor compound present within the digester; - a step (6) of identifying one or more microorganisms exhibiting limiting kinetics present in the digester; - a step (7) of predicting the maximum growth rate of the one or more determined microorganisms; - a step (8) of identifying the maximum admissible load in the digester; and - a step (9) of calculating the operating parameter of the digester according to the identified maximum admissible load.
