City of West Palm Beach, Florida: Automating Water Flow and Dosing Control

, ,

The City of West Palm Beach’s Water Treatment Plant still relied on manual operations to control chemical dosing and pumping. We teamed up with Innovative Control, Inc. to completely redesign the plant’s control system for advanced, automated control.

We added an additional 1500 I/O points to the control system and integrated PID controllers throughout the plant. Running custom calculations, the controllers manage water flow, level, and chemical dosing. Equipment modules running SFCs control basin and supply pumps, automatically starting and stopping pumps based on level and flow readings, with pump usage balanced based on accumulated run time.

We re-wrote all existing code based on object-oriented template design. Each graphical object has a corresponding PLC object, designed using data structures. Control module instances are easily deployable through an advanced operator user interface. Diagnostic information is sent as an object (tag), empowering the operator to easily troubleshoot the system and diagnose problems when they occur. Historical data is automatically archived per object, making control system maintenance easy and intuitive.

The site operators enthusiastically adopted the new control system design, with one saying that we “hit it out of the park!”
