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
