RSE’s modular approach enables systems to be factory-built and tested before being transported to site, supporting rapid installation and deployment. Standard m-MBBR® and m-MBR® systems are designed for conventional road transportation and can be brought fully operational quickly, making them suitable for both permanent and temporary applications.

The modular platform also provides scope for future capacity expansion. During front-end engagement, RSE assesses process data and provides early technical information covering footprint, power demand, scalability and operational parameters. This enables engineering teams to assess integration requirements and develop a solution that can accommodate future treatment needs.

The m-MBBR® can be configured to address different treatment objectives. For BODreduction, the standard module uses a three-stage biological reactor with integrated two-phase solids separation. For BOD and total nitrogen reduction, the first stage operates asan anoxic zone for denitrification, while the second and third stages provide BOD removal,nitrification and additional ammonia reduction. Alternative configurations are available for BOD and ammonium (NH₄) reduction, while thesystem can also be deployed as a tertiary nitrification stage where existing treatment worksare failing to meet ammonia discharge consents. This can operate as a standalone facilityor be integrated into existing works as a side-stream reactor.

The modular approach allows treatment capacity to be matched to project requirements and scaled as demand changes. The technology can treat wastewater flows exceeding 150,000 m³/day, with applications capable of reducing flows to as little as 25 m³/day.

Three standard m-MBBR® module sizes are available, with maximum capacities ranging from approximately 3.5 l/s to 10.5 l/s per module. Multiple modules and configurations can be used to provide the required overall treatment capacity.

The m-MBBR® is designed to provide a flexible platform that can be integrated with existing treatment processes or deployed as part of a new treatment train. Its modular construction allows additional treatment capacity to be introduced without necessarily requiring a conventional site-built plant.

For example, the technology can be used as a tertiary nitrification stage to address ammonia compliance issues, or as a side-stream reactor within existing works. Its compact footprint and scalable design can also support upgrades where available space or existing infrastructure is constrained.

The m-MBR® is designed for applications where consistently high-quality effluent, a compact footprint and scalable treatment capacity are required. The system combines aerobic biological treatment with submerged membrane filtration, eliminating the requirement for secondary clarification or tertiary filtration.

Key considerations include the required treatment capacity, available footprint, feed characteristics, integration with existing processes and the required effluent quality. The system can provide treatment rates from 5 to 900 litres per second and can be installed within an existing tank or a prefabricated tank.

MBR systems deliver consistently high effluent quality, provide a significantly smaller footprint than conventional activated sludge systems, and perform well under varying influent conditions. They can also support water reuse initiatives and help maximise treatment capacity on constrained sites.

Yes. MBR technology is frequently used to increase treatment capacity, improve effluent quality or bring existing assets into regulatory compliance. RSE’s modular m-MBR® can be incorporated into existing infrastructure or installed within prefabricated treatment systems.

Because membrane separation replaces large clarification processes, m-MBR® systems can achieve high treatment performance within a compact footprint. This makes them ideal for urban locations, remote communities, industrial facilities, campuses and resort developments where space is limited.
