Membrane Bioreactor Operations & Maintenance

Guidance for optimal MBR performance

Use this operational pathway from routine care and validated data through first response, recovery, solids control, energy optimisation, and SCADA decisions.

Operations & Maintenance Guide Index

Choose the operating pathway that matches the current decision: stabilise and monitor, recover and control solids, or optimise and automate.

Operate and monitor

Start with stable operation

1O&M Best PracticesRoutine operational foundations for stable MBR performance.2Monitoring & TroubleshootingValidate process and membrane trends before changing operation.3pH Monitoring, Troubleshooting & SolutionsTrace abnormal pH through biology, membranes, equipment, alkalinity, and influent conditions.

Recover and control solids

Respond and restore

1Fouling Troubleshooting: TMP, Permeability & First ResponseThe operator quick guide for first checks and safe escalation.2Start-up, Commissioning & RecoveryBuild a baseline, ramp safely, and recover from an upset.3Solids Inventory, Wasting & Dewatering SidestreamsConnect MLSS, SRT, wasting mass, and return loads.

Optimise and automate

Improve with validated data

1Energy & Aeration OptimisationEstablish an energy baseline without compromising process constraints.2Instrumentation & SCADAMeasurement quality, alarms, data trends, and control boundaries.
