Introduction
The global membrane bioreactor (MBR) market was valued at about USD 4.45 billion in 2024 and is projected to grow at a CAGR of 7.9% between 2025 and 2032, reaching USD 8.21 billion by 2032, according to Stratview Research. Growth is being driven by mounting water stress, stricter discharge regulations, and the need for efficient, space-saving wastewater treatment systems.
Applications
MBR systems are widely used for municipal wastewater treatment, offering compact footprints and high-quality effluent ideal for reuse. They also serve industrial wastewater needs, particularly in sectors such as pharmaceuticals, food & beverages, and chemicals, enabling sustainable water management and resource recovery.
Key Drivers
Several major factors fuel the MBR market:
- Stringent environmental regulations demanding advanced treatment and water reuse.
- Urbanization and industrialization, leading to greater wastewater generation.
- MBR’s compact design and superior solid removal, enabling space-efficient facilities.
- Growing emphasis on circular water economies and water reuse in drought-prone and densely populated regions.

Future Opportunities
Looking ahead, the MBR market is ripe for innovation. Integration with advanced treatment methods — such as reverse osmosis, nanofiltration, or advanced oxidation — can improve contaminant removal and support nutrient recovery. There’s also opportunity in modular and decentralized systems, which offer flexible scaling and deployment in remote or rapidly growing urban areas. Emerging markets in Asia-Pacific are expected to lead growth, driven by rising populations, expanding infrastructure, and water scarcity.
Conclusion
Membrane bioreactors represent a powerful solution for modern wastewater management, combining biological processing with membrane filtration to deliver compact, high-performance systems. With strong regulatory support, technological advances, and growing demand for water reuse, the MBR market is well positioned for sustained growth and innovation.
