The course will cover the fundamental and advanced topics in the modelling of wastewater treatment plant with emphasis on application of GPS-XTM as a simulation tool. Considering the importance of energy conversation, greenhouse gas reduction, resource recovery and process optimization, the modelling of wastewater treatment plant has become an important topic for every process engineer.

GPS-XTM is state of the art, most comprehensive simulator for modelling the wastewater treatment plant. In addition to advanced topics, the workshop will provide hands-on experience on the software to conduct a selected modelling study.

The course is intended for existing modelling practitioners as well as those interested in learning about basic modelling and simulation.

Topics to be covered include:

  • modelling and simulation basics
  • the GPS-XTM software interface
  • setting up and calibrating models
  • advanced modelling tools


Course participants are required to bring a laptop suitable for simulation exercises.

GPS-XTM will be supplied free of charge for the duration of the course (+ 2 weeks).
