Chemical Dosing Optimizer Bot

AI 88%Live in demo

Most plants dose to a fixed setpoint sized for worst-case raw water, which means paying for overdose on every ordinary day. The Dosing Optimizer models demand from raw-water quality, flow and temperature and recommends the lowest dose that keeps residual, turbidity and CT compliance inside the target band — while tracking chemical inventory and lead-time exposure.

Guardrails

  • Compliance band is set by the utility, never by the model.
  • Recommendations suspend automatically during raw-water upset events.
  • Advisory-only feed changes; the operator confirms every setpoint move.
