The model library and how to customise it

This one-day advanced WEST training provides you with a good understanding of the WEST Model Library. You will learn how to customise it by adding your own models.

WWTP modelling is essential for scientists and practitioners who deal withexploring design alternatives, optimising plant operations (e.g. to improve performance and reduce cost), implementing control strategies, etc. WWTP modelling is also an ideal learning tool that may be used (e.g. by plant operators) to investigate the complex process dynamics and interactions that characterise a
modern WWTP.

WEST is an extremely user-friendly software tool that combines advanced modelling features such as objective evaluation and uncertainty analysis with extraordinary performance, full flexibility and openness.
