A link is required to translate between biological based and physical or chemical mediated processes to develop plant-wide modeling of wastewater treatment. This model mediates the interaction between the Modified Anaerobic Digestor Model 1 (ADM1) and the Modified Activated Sludge Model 2d (ASM2d).
The model relies on the following key assumptions:
- supports only liquid phase
- supports only Modified ADM1 to Modified ASM2d translations

.. currentmodule:: watertap.unit_models.translators.translator_adm1_asm2d
The translator degrees of freedom are the inlet feed state variables:
- temperature
- pressure
- volumetric flowrate
- solute compositions
- cations
- anions
This model provides two ports:
- inlet
- outlet
