Aeration assessment must consider energy use and treatment stability together. Web-SCADA helps organize evidence; the plant's engineering and operations teams approve any change to operating conditions.
Confirm what the energy measurement covers
Identify blowers, process areas and other loads included in the meter. Rated motor power or percentage speed does not directly establish actual energy consumed. Agree suitable measurements with the responsible equipment and electrical teams.
Link energy to process conditions
Align energy records with DO, flow, available laboratory results, equipment states and maintenance. Compare operating modes and check signal quality. A DO chart alone does not establish excess aeration.
Plan a bounded trial
Define approval, monitoring, equipment limits, acceptance conditions and reasons to stop or return to the previous mode. Begin with read-only analysis where appropriate. DO targets and control settings must fit the specific process.
Evaluate beyond a short favourable period
Compare kWh and kWh/m³ within the same measurement scope, while checking influent and treatment outcomes. Record alarms, downtime and added maintenance. Distinguish measured results from estimates when data or dedicated metering is incomplete.
Records to check
| Record group | Evidence to review |
|---|---|
| Energy | Actual readings and measurement boundary |
| Process | DO, flow, quality and operating mode |
| Trial | Approval, stopping conditions and outcome |
Prepare an assessment with X-IRIS
Bring the aeration diagram, blower list, meter boundaries, process history and maintenance records. Review the implementation roadmap and request an assessment to agree a scope that can be tested.
Technical reference: EPA's Energy Management Guidebook recommends measuring aeration equipment power during an energy assessment rather than relying only on estimates.
