Urban water

Explore advanced modelling features in WEST

Fee: No charge*
Time commitment: Four modules, approximately two hours per module. Expected eight hours in total.


Wastewater treatment plant (WWTP) modelling is essential for scientists and practitioners who want to explore design alternatives, optimise plant operations to improve performance and reduce costs, and implement control strategies. WWTP modelling is an ideal learning tool that may be used by plant operators to investigate the complex process dynamics and interactions that characterise a modern WWTP.

This course will enable you to take the next step in wastewater process modelling by exploring the power of advanced controllers, model calibration and scenario analysis in WEST. You will be guided through a typical workflow in WEST for improving a basic activated sludge process layout by assessing the impact of advanced aeration control, calibrating the model against measured data and optimising effluent quality and energy consumption.

WEST is a sophisticated modelling and simulation tool for wastewater process and integrated urban water systems. Unique and powerful features of WEST include: (i) the ability to implement control models of unlimited complexity; (ii) the possibility of defining custom objectives as performance indicators; (iii) advanced experiment types, e.g. scenario and uncertainty analysis.

Are you a wastewater process modeller? Do you know the basic features of WEST and wish to explore modelling in WEST beyond the basics? Do you have knowledge of basic terminology for wastewater process engineering and activated sludge modelling principles? Would you like to explore some of the powerful key features of WEST that may help you improve the performance of your treatment facilities? If yes, you will benefit from this free, self-paced course.

Upon completion of the course, you will be able to critically assess your process layouts, improve the predictive capability of the model by closely matching with measured data, test options for implementing control strategies and optimise effluent quality and operational costs.

Each module includes videos and other materials you will need for training and quizzes. It will take you around eight hours to complete the course at a time that fits your needs and requirements – from the comfort of your own office, home or any convenient location.

Module 1 - Change model instance: ASM1 to ASM2
Reviewing the influent model (fractionation)

Module 2 - Incorporate control models
