Drinking Water Simulator for Proactive Operation and Training

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
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: the project Nine partners of which four Dutch water supply companies
Waterspot: the product
Waterspot Article 1. Software layout Article 2. Hydraulic model for Harderbroek Article 3. Integration of a hydraulic model and a process model for Wim Mensink

A drinking water treatment plant simulator that connects: Models for water quality Models for water quantity Control model Object model Waterspot: software layout
Models for water quality, Stimela Waterspot: software layout
Models for water quantity, EPAnet Waterspot: software layout
Control model, USE Waterspot: software layout
Object model, USE Waterspot: software layout
EPANET elements Library Waterspot: hydraulic model Harderbroek
Model definition Waterspot: hydraulic model Harderbroek
Calibration: current frequency to control effluent pumps’ speeds Waterspot: hydraulic model Harderbroek
Validation, wells Waterspot: hydraulic model Harderbroek
Validation, cascade aerators Waterspot: hydraulic model Harderbroek
Validation, influent rapid sand filters Waterspot: hydraulic model Harderbroek
Case: pump speeds during filter backwash Waterspot: hydraulic model Harderbroek
Validated EPAnet model Waterspot: hydraulic model + process model Wim Mensink
Stimela model for Mensink has been set up. 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 Waterspot: hydraulic model + process model Wim Mensink
