WEST – modelling wastewater treatment plants


WEST® is a powerful and user-friendly tool for dynamic modelling and simulation of wastewater treatment plants (WWTP). The extensive state-of-the art model and process library of WEST® enables you to model and evaluate almost any kind of modern WWTP.

WEST® is designed for engineers or professionals who want to simulate processes where physical, biological or chemical processes take place in water. With a mathematical model of a WWTP you will have the possibility to test any scenario of interest and to track the associated treatment efficiency as well as operational cost.

A typical WEST® application will help you to:

  • Identify problems and costs
  • Scenario simulations with current and future influent flow rate profiles
  • Scenario simulations with current and future wastewater composition
  • Identification of bottlenecks
  • Identification of costs
  • Test of operation robustness and risk analysis
  • Design to solve problems and save money
  • Evaluation of possible plant layouts
  • Evaluation of possible control systems
  • Optimize to solve problems and save money

With WEST® you can easily integrate your own know-how and has an open structure that allows for integration with supervisory systems (SCADA) and data management systems.
