.TransiEnt.Producer.Gas.BiogasPlant.Base.ADM1.ADM1_Functions.ADM1_Inhibition_BSM2

Information

1. Purpose of model

This function calculates the inhibition coefficients for the adm1 model. It considers inhibtion due to an unfavorable pH-value, an excessive concentration of hydrogen or ammonia and an insufficient nitrogen concentration.
