Base class of WWTP modelling by ASM3
Diagram of ASM3baseOpen the diagram

Extends from Interfaces.stoichiometry (ASM3 stoichiometric coefficients).

Information

This partial model provides connectors and equations that are needed in the biological 
components (nitrification and denitrification tank) for ASM3 wastewater treatment plant models.
Parameters are coded according the ASM3 [1] standard distribution.
Changes to this parameters are subject to the modeller.
