Drinking WaterSimulator for

Proactive Operation and Training

slide3

Why Waterspot?

Drinking water treatment operation changes from 24/7 shifts…

slide4

Why Waterspot?

... to supervisor shifts in office hours…

slide5

Why Waterspot?

... opening opportunities for advanced process control…

Why Waterspot?

... but resulting in a lack of natural training at the same time.

slide8

Why Waterspot?

The need for well-trained supervisors will stay…

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

Waterspot: the project

Started on the foundations of the Promocit project (development of Stimela water quality models)

Co-funded by Dutch Ministiry of Economic affairs

Waterspot: hydraulic model + process model Wim Mensink

  • Work in progress:
  • Calibration and validation Stimela model
  • Connect EPAnet and Stimela with in Waterspot
  • Simulate hydraulic operation of Mensink
