Process Modelling for Water Treatment Professionals

This interactive 12hr course is built around forecasting water quality and addressing treatment plant performance issues arising from changing feed water conditions.

This is an interactive two-day course built around forecasting water quality and addressing treatment plant performance issues arising from changing feed water conditions. Engineers will learn to understand the influence of water chemistry on process design and how to use this knowledge to optimise performance. Participants will also design new treatment plants and size equipment using comprehensive software that integrates material and heat balancing, equipment sizing, stream property and solubility prediction.

Each module includes realistic scenarios for advanced water treatment applications including boiler feedwater, cooling water blowdown, industrial wastewater, seawater desalination, mine dewatering and brine management. Up to 21 technologies in water treatment will be explored during the sessions.

Participants will receive detailed notes for each module and a three month free subscription to AqMBTM process simulation software for water treatment.

Issues addressed


  • Module 1 – Water Chemistry Essentials
    • A comprehensive overview of essential water quality properties for treatment plant design
    • Basic theory around chemical equilibrium, reaction kinetics and redox potential
    • An introduction to solubility modelling, the impact of dissolved gases on redox and equilibrium chemistry and how process kinetics can affect scale formation and corrosion.
  • Module 2 – Unit Operation Types
    • An overview of most technologies used in water treatment
    • Modes of action defining separation for each technology

  • Module 3 – Configuring Flowsheets for Process Design
    • Developing a feed water scenario for typical and boundary condition
    • Process design considerations, constraints, performance objectives and assumptions
    • For a given feed water specification, generate a first pass integrated process design and mass balance
    • Identify which parameters impact equipment performance and treated water quality.


  • Module 4 – Process Modelling for Performance Optimisation
    • An overview of each unit operation, their key process parameters (design/operational) and how they are used in each model simulate equipment performance
    • Learn how to optimise a process design for performance objectives by refining process design parameters for each unit operation
    • Conduct a solubility survey to understand the interaction of inorganic/organic species under different conditions and what does this really mean for the performance of each unit operation
