Wastewater treatment process modelling


Optimise your WWTP by targeting effluent quality, energy, and cost


WEST is the premier simulation tool tailored for dynamic modelling and simulation within wastewater treatment plants (WWTPs). Designed to support operators, engineers, and researchers, it offers a robust platform for delving into the intricacies of physical, biological, and chemical processes within WWTPs, sewer systems, and rivers.


By prioritising the refinement of plant design, operations, and automation, WEST facilitates the optimisation of effluent quality, energy consumption, and cost efficiency. Equipped with dynamic condition simulations and advanced experimental features such as Uncertainty and Sensitivity Analysis, WEST emerges as an indispensable asset for the evolution of wastewater treatment facilities towards a future-ready state.
