Why it matters
Without AI, improper ozone dosing or delayed alarms can lead to unstable water chemistry, bromate formation, or unsafe conditions during maintenance and dives, risking animal welfare and accreditation status.
From design to safety
Design
Designing AI-enabled ozone system
Assess data flows, sensors, and equipment interfaces. Define dose- response models, safety margins, and record schemas for an integrated ozone loop. Specify data exchange standards, alarm hierarchies, and audit trails for validation.

Build
Commissioning and integration
Install sensors and controllers, calibrate ORP, install bromate risk mitigations, establish alarm thresholds, and wire AI decision modules into the LSS control system. Validate hardware redundancy and failover paths.

Operation
Real-time dosing and monitoring
AI monitors ORP, residual ozone, and water quality, adjusts dosing, flags anomalies, and logs dosing events to the water laboratory records. Integrate with dive log and exhibit maintenance work orders.

Maintenance
Predictive maintenance for ozone loop
Continuous data collection on pump, contactor, and degassing tower wear; AI schedules filter and component servicing to prevent drift and ensure consistent ozone output. Include spare parts forecast and calibration cadence.

Safety
Safety, compliance, and alarms
AI enforces permit limits, bromate risk checks, emergency shutdowns, dive-safe notifications, and accreditation-ready logs with role-based approvals. Maintain incident reports, training records, and deviation logs.

Part by part
- 1
ozone generator
- Watch for
- unusual ozone output drift, sudden pressure drop, or heat rise indicating catalyst or compressor wear.
- AI action
- reads output rate and temp; triggers maintenance or alarm if deviation exceeds threshold.
- 2
ozone contactor
- Watch for
- coating or corrosion on contactor internals, slower dissolution rate, leak indicators.
- AI action
- monitors contactor current and voltage; adjusts stage timing to maintain target ozone transfer.
- 3
ORP probe
- Watch for
- drifted calibration, electrode fouling, slow response to changes in ozone dosing.
- AI action
- analyzes ORP trends; requests calibration or cleaning when drift exceeds limit.
- 4
degassing tower
- Watch for
- backpressure rise, packing degradation, reduced gas transfer efficiency.
- AI action
- reads differential pressure and gas flow; schedules inspection and packed-bed replacement.
- 5
residual ozone monitor
- Watch for
- residual ozone high after contactor, indicating bypass or overflow.
- AI action
- flags anomalies and trims dosing to maintain safe residuals.
- 6
bromate risk monitor
- Watch for
- bromate formation indicators, high oxidant stacking, questionable water chemistry.
- AI action
- evaluates bromate risk model and prompts corrective action if risk crosses threshold.
Worked example
Catching bromate risk before a routine exhibit turnover
Illustrative scenario with sample data.
During a gallery turnover, AI detects rising residual ozone and potential bromate risk, prompting a controlled reduction in dosing and a scheduled maintenance window.
Signal in
timestamp:2026-11-08T10:15:00Z; ORP: 290 mV; residual_ozone: 0.65 mg/L; flow: 1200 L/min; temp: 24.2 C; exhibit_id: 3; operator: lead aquarist; bromate_potential: high; calibration_status: OK
System out
alert_id: OZ-AL-542; action: reduce ozone dose to 75% of target; schedule contactor inspection; log event to water-lab records; notify dive safety officer; update maintenance work order.
Human sign-off: Curator and life support supervisor review AI alert, approve dose adjustment, and confirm inspection window; QA approves updated SOP segment.
How to roll it out
Phase 1
Weeks 1 to 4
Install core sensors, initialize AI models, and align thresholds with existing LSS control schema.
Phase 2
Weeks 5 to 8
Run parallel data streams; validate decision outputs against manual dosing, calibrate alerts, train staff.
Phase 3
Weeks 9 to 12
Go-live with full AI control; establish routine audits and accreditation-aligned reporting.
Where people stay in charge
- Decisions affecting animal welfare and safety must be signed off by the Water Quality Manager or Life Support Engineer.
- All changes to dosing thresholds require written approval from the Senior Aquatics Veterinarian and Dive Safety Officer.
- Automated shutdowns for bromate risk or chemical handling must undergo human verification before execution.
Questions owners and crews ask
What exactly does the AI watch in an ozone dosing system?
The AI watches ORP, residual ozone, flow, temperature, and equipment health; it decides dosing adjustments, maintenance needs, and safety alarms, with results logged for records.
Who approves AI-driven changes to ozone dosing?
The Water Quality Manager and Dive Safety Officer review and approve all AI-driven dosing changes, ensuring welfare, safety, and regulatory compliance.
How is bromate risk addressed by the AI?
The AI monitors bromate risk indicators, adjusts ozone levels, and prompts preventative maintenance or procedural changes to minimize formation risk.
What records are produced for accreditation?
Dosing events, ORP trends, residual ozone logs, maintenance actions, and safety alerts are compiled into the water laboratory and life support records for inspections.
