modelASM1base
Base class of WWTP modelling by ASM1
Extends from Interfaces.stoichiometry (ASM1 stoichiometric coefficients).
Information
This partial model provides connectors and equations that are needed in the biological
components (nitrification and denitrification tank) for ASM1 wastewater treatment plant models.
Parameters are coded according the ASM1 [1,2] standard distribution.
Changes to this parameters are subject to the modeller.
