Energy Optimization Bot
AI 93%Live in demoAeration is typically 50–60% of a water reclamation facility's total electricity spend and is the largest controllable opex line in the plant. The Energy Optimization Bot builds a rolling model of blower power versus dissolved-oxygen demand, influent load and utility tariff windows, then continuously recommends the lowest-energy operating envelope that still holds the permit margin.

Specific energy vs target · rolling 24 hours
Every point is normalized to treated volume (kWh per million gallons), so a load swing doesn't read as an efficiency change.
Recommended energy actions
Each action carries an expected kWh delta, a dollar value, and the reasoning behind it.
Trim Basin 3 DO setpoint 2.4 → 1.9 mg/L (00:00–05:00)
AI 94%Overnight ammonia load is 38% below daytime peak; nitrification margin holds at 1.9 mg/L.
Rotate blower lead from #2 to #3
AI 91%Blower #2 specific power has degraded 9% since bearing wear onset; #3 is 6.2% more efficient at this duty.
Shift Lift Station 7 & 14 pump-down to off-peak window
AI 87%Wet-well capacity allows a 90-minute deferral without SSO exposure; avoids 4–7 pm demand tariff.
Energy spend breakdown
Aeration dominance is why this bot targets blowers and DO control first.
Guardrails
- Never trims DO below the biological floor required for nitrification.
- Advisory only — no closed-loop writes to the DCS unless the utility explicitly enables it.
- Savings claims use a weather- and load-normalized baseline, not a raw year-over-year delta.

DeploymentRequires blower-level power metering and at least one DO probe per aeration basin. Typical stand-up 2–3 weeks on existing SCADA tags.
Other active bots
NPDES / Permit Compliance Reporting Bot
Auto-generates regulatory submission data from plant telemetry and flags exceedance risk before the sample is pulled, with an audit trail per parameter.
Typical: 30+ staff hours/month recovered
Chemical Dosing Optimizer Bot
Optimizes chlorine, polymer and alum dosing against real-time flow and quality targets rather than fixed setpoints, holding compliance margin at the lowest feasible dose.
Typical: 6–11% chemical spend reduction
