ADM1 to ASM2d Translator

Introduction

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 Digester 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

Degrees of Freedom

The translator degrees of freedom are the inlet feed state variables:

  • temperature
  • pressure
  • volumetric flowrate
  • solute compositions
  • cations
  • anions

Ports

This model provides two ports:

  • inlet
  • outlet

Equations and Relationships

Description Equation
Volumetric flow equality F_{out} = F_{in}
Temperature balance T_{out} = T_{in}
Pressure balance P_{out} = P_{in}
Fermentable substrate conversion S_{F, out} = \Sigma _{r1} C_{r1, in}
Acetic acid conversion S_{A, out} = \Sigma _{r2} C_{r2, in}
Unchanged component conversions C_{u, out} = C_{u, in}
Ammonium conversion S_{NH4, out} = S_{IN, in}
Phosphate conversion S_{PO4, out} = S_{IP, in}
Biodegradable particulate organics conversion X_{S, out} = \Sigma _{s} C_{s, in}
Zero-flow component conversions C_{z, out} = 0
