Membrane Bioreactor Case Studies
See how MBR technology has been applied in municipal reuse, industrial wastewater treatment, and urban buildings. Start with a project that matches your interest, then open the full case study for its process, scale, treatment objective, and operating lessons.
A clear way to explore the case studies
The project pages below explain what each MBR system was built to do, how it was configured, and what can be learned from the available information. The reporting framework explains how project facts and limitations are documented.
Find a project that matches your interest
This quick comparison helps visitors choose where to begin. The projects serve different purposes and should not be treated as a performance ranking. “Not reported” means that the current case page does not publish a value.
| Case | Application and context | Configuration or objective | Reported scale or indicator | Information shown | Read for |
|---|---|---|---|---|---|
| Beenyup | Advanced water recycling and managed aquifer recharge; Perth, Western Australia [CS-S2] | UF–RO–UV advanced water recycling plant; aquifer recharge. This is not presented as an immersed MBR case. [CS-S2] | Stage 1: 14 GL/year; Stage 2: 28 GL/year. Actual treatment depends on wastewater availability. [CS-S2] | Owner/regulator sources | Reuse barriers, critical control points, hydrogeology, and regulatory context |
| Arla Foods | Industrial dairy wastewater; Vimmerby, Sweden [CS-S3] | Rotating-disc ceramic sidestream MBR with biological nitrogen removal and conditional phosphorus control [CS-S3] | Approximately 400–450 m³/day reported; historical 2015 operating data [CS-S3] | Technical case sources | High-strength variable dairy/CIP wastewater, rotating membrane shear, and cleaning/control strategy |
| The Solaire | Decentralized in-building reuse; Battery Park City, New York [CS-S1][CS-S4][CS-S5] | Basement-installed MBR for toilet flushing and cooling-tower make-up [CS-S4][CS-S5] | Up to 25,000 US gpd (94.6 m³/day) reported historical capacity [CS-S4][CS-C1] | DEC, provider, and technical sources | Space-constrained decentralized reuse and building integration |
The comparison summarizes the information currently shown on each case page. Open the full case study for sources, context, and limitations before using any detail for design, procurement, permitting, or due diligence.

How claims are sourced
Each material figure should be traceable to a named source and its stated boundary. A citation does not make a manufacturer claim independent evidence, and a unit conversion does not turn a design capacity into actual operating flow.
- Confirmed source support: the source directly supports the claim for the stated project, period, and boundary.
- Manufacturer/provider claim: the source reports the value or configuration; it is shown with attribution and is not treated as independent verification.
- Editor calculation: MBR Network derives a conversion or comparison from cited inputs; the formula, factor, rounding, and limitations must be stated.
- Unsupported / needs qualification: the claim is removed, narrowed, or held out of comparative/design conclusions until a stable source is verified.
Stable source register:
[CS-S1] Government report, 2010: NYS DEC, Potential Reuses of Greywater and Reclaimed Wastewater in New York State, stable PDF. Supports the cited Solaire reuse/capacity context; it is not evidence of constant actual flow.
[CS-S2] Owner source, n.d.: Water Corporation WA, Groundwater replenishment, stable page. Supports Beenyup ownership, reuse, and managed-aquifer-recharge context; “n.d.” means no publication date was displayed.
[CS-S3] Technical case account, 2020: Arla milk powder factory MBR plant for treating dairy wastewater, The MBR Site, stable article. Supports the Vimmerby configuration and historical reported operating data; provider/manufacturer claims remain attributed claims.
[CS-S4] Provider project record, n.d.: Natural Systems Utilities, Battery Park, stable project page. Supports the Solaire system/application context; provider-reported information is not independent verification.
[CS-S5] Technical paper, 2021: Su, The Solaire, New York, NY, stable PDF. Supports the documented high-rise reuse context and reported capacity basis.
[CS-C1] Editor conversion: 25,000 US gpd × 0.00378541 = 94.6 m³/day, rounded to one decimal place. This converts the reported US-gallon-per-day value; it is not a claim of constant actual flow.
What to keep in mind
Every treatment plant has its own wastewater, climate, permits, equipment, and operating practices. A result from one project may not transfer directly to another, so read each figure together with its project context.
The existing MBR Case Study Reporting Framework defines the minimum context, evidence, source, performance, limitation, and lesson fields used for future updates. It also explains why one project’s operating practice should not be copied as a universal design or O&M instruction.
Keeping the project information reliable
Case studies are reviewed and corrected when better public information becomes available. Material claims are mapped to visible source IDs with source type, publication year or n.d. status, stable document URL, calculation or conversion basis, and scope limitations. This helps visitors distinguish documented facts, manufacturer-reported values, editor calculations, and claims that still require qualification.
These pages are educational references, not endorsements or project-specific design instructions. For deeper technical context, visit the Process Flow Diagrams, Membrane Technology index, and Operations & Maintenance sections.
Last hub review: October 7, 2026. The current index contains three published project summaries; additional cases should use the reporting framework and claim-level source record before publication.
