Why Waterspot? Drinking water treatment operation changes from 24/7 shifts…
... to supervisor shifts in office hours… Why Waterspot?
... opening opportunities for advanced process control… Picture: Alex van Delft DSM Why Waterspot?
... and virtual commissioning… Picture: Alex van Delft DSM Why Waterspot? Picture: Siemens
... but resulting in a lack of natural training at the same time. Picture: Alex van Delft DSM Why Waterspot?
The need for well-trained supervisors will stay… Picture: Alex van Delft DSM Why Waterspot?
… or even increase in the next ten years as a consequence of ageing. Picture: Alex van Delft DSM Why Waterspot?
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
