Water Treatment Chemical Dosing: Feed-Forward Flow Pacing & Feedback PID Coagulation

Master chemical dosing automation: combining raw water flow pacing (feed-forward) with streaming current and pH feedback PID to optimize alum and polymer dosing while meeting EPA turbidity standards.

  • Pure feedback PID fails on chemical dosing due to the 5 to 15 minute lag before downstream water chemistry responds.
  • Feed-forward flow pacing instantly adjusts dosing pump speed proportionally when raw plant intake flow changes.
  • Streaming current detectors measure colloidal charge neutrality, allowing precise real-time coagulant optimization.
