FuGuang Smart Phosphorus Control

Agent-driven dosing decisions for water treatment, with human supervision — out-of-range actions require human confirmation.

About this page

This page only depicts a conceptual architecture and capability summary. No customer production data, sensor readings, or live system UI is shown.

In short

FuGuang Smart Phosphorus Control is an agent-driven dosing design for water treatment. Sensor arrays feed water quality, flow and dosing figures into the agent context at second-level latency; the agent combines threshold models with LLM reasoning to propose a dose and a risk level; only after an operator confirms it does the actuator adjust, and the outcome flows back as an adaptive closed loop. The key difference from fixed PID control is that any decision outside the critical thresholds requires human confirmation and is fully audit-logged — the agent advises, it does not decide. This page shows architecture and capability only, with no customer production data.

What the agent takes off people's plates

Core capabilities

01

Real-time sensing

Sensor arrays feed water quality, flow, and dosing metrics into the agent context at second-level latency.

02

Agent decisioning

Threshold models combined with LLM reasoning produce dosing recommendations and risk levels for human review.

03

Actuation & feedback

Actuators adjust dosing, results feed back to the agent to form an adaptive closed loop.

04

Human oversight & compliance

Decisions outside critical thresholds require human confirmation; all actions are audit-logged per regulation.

Side by side

Agent-driven dosing vs fixed PID control vs operator experience alone

DimensionOperator experience aloneFixed PID controlAgent-driven with human oversight
Basis for the decisionA senior operator's experience and shift habits — it varies with the personA pre-tuned parameter curve, bound to the conditions it was tuned forSecond-level quality, flow and dosing data, with threshold models and LLM reasoning producing the recommendation together
Keeping up when conditions shiftSomeone has to notice on a round and then adjust; the lag equals the inspection intervalParameters stay fixed; going outside the tuned range means an engineer must retuneActuation results flow back through the sensors, forming an adaptive loop that keeps correcting
Who owns out-of-bounds situationsEntirely personal judgement, with blurry accountabilityThe controller does not assess risk; anomalies still depend on a human noticingAnything outside the critical thresholds requires human confirmation; the agent only issues a recommendation and a risk level
TraceabilityPaper logs and verbal handover — hard to reconstruct afterwardsRecords the control values but not the reasoning behind themRecommendation, confirmation and actuation are all audit-logged for industry compliance reviews

Verifiable facts

Numbers and sources

The design is a four-stage closed loop: sensor array → agent decision layer → operator approval → dosing actuator, with the result flowing back through the sensors.

The agent never acts alone: decisions outside the critical thresholds require operator confirmation, and every action is audit-logged to meet industry compliance requirements.

Where it fits

When this approach does not apply

  • What this page describes is an architecture and a capability set, not a delivered, acceptance-ready system. No field sensor readings, process parameters or system screens appear anywhere on it, and the outcome for any specific plant has to be assessed separately against its influent conditions and existing instrumentation.
  • The design does not take over safety interlocks. The agent sits in the loop as an adviser: any action beyond the critical thresholds must be confirmed by a qualified operator first, and any deployment that removes the human from the loop falls outside what this solution covers.
  • Instrumentation caps the quality of every decision. The accuracy, sampling delay and calibration interval of the online water-quality analysers determine what the agent can see at all; with drifted or long-uncalibrated instruments, better reasoning only amplifies the error.
