Why Waterspot? Summary • Offline • Training and testing of operation supervisors in company look & feel • Model-based process (control) optimisation • Open the use of process models to a wider group • Virtual commissioning of software updates • Online • Advanced process-control to delay investments in production capacity, and to obtain a more stable water quality • Alerts on malfunctioning online measurements
