Membrane Bioreactor Market Report 2026

The membrane bioreactor market size has grown rapidly in recent years. It will grow from $4.65 billion in 2025 to $5.2 billion in 2026 at a compound annual growth rate (CAGR) of 11.7%. The growth in the historic period can be attributed to stringent wastewater discharge regulations, rapid urbanization increasing sewage volumes, limited availability of freshwater resources, rising industrial wastewater generation, demand for higher effluent quality standards.

The membrane bioreactor market size is expected to see rapid growth in the next few years. It will grow to $8.1 billion in 2030 at a compound annual growth rate (CAGR) of 11.8%. The growth in the forecast period can be attributed to increasing investments in advanced wastewater treatment infrastructure, rising demand for water reuse and recycling, technological advancements in membrane efficiency, expansion of industrial treatment capacity in emerging economies, supportive government initiatives for sustainable water management. Major trends in the forecast period include increasing adoption in municipal wastewater treatment, shift toward compact and decentralized treatment systems, rising preference for submerged membrane configurations, advancements in fouling resistant membrane materials, integration of biological nutrient removal processes.

The rising prevalence of water pollution is significantly contributing to the growth of the membrane bioreactor market. Water pollution occurs when toxic substances, often chemicals or microorganisms, are released into streams, rivers, lakes, or oceans. These incidents frequently stem from the scarcity of clean and drinkable water. As water pollution increases, membrane bioreactors become a viable alternative for water treatment through microfiltration or ultrafiltration. For example, in August 2025, Gov.uk, a UK-based government information portal, reported a continued rise in pollution incidents from sewerage and water supply assets, with a 29% increase between 2023 and 2024. Therefore, the growing prevalence of water pollution is expected to boost demand for membrane bioreactors during the forecast period.

Major companies operating in the membrane bioreactor (MBR) market are focusing on developing innovative solutions, such as advanced membrane-based wastewater treatment systems, to meet the rising demand for high-efficiency, compact, and reusable water treatment technologies. MBR technology integrates biological treatment with membrane filtration to produce higher-quality effluent than traditional activated-sludge processes. For instance, in June 2025, Almasa Environmental Solutions, a UAE-based wastewater treatment company, launched the country’s first MBR manufacturing facility, marking a major step forward in regional water-treatment innovation. The newly developed MBR units use semi-permeable membrane filtration combined with biological degradation to efficiently remove suspended solids, pathogens, and organic contaminants. These systems offer a smaller footprint, higher effluent clarity, reduced sludge generation, and improved operational stability compared with conventional clarifiers. They are suitable for municipal sewage, industrial wastewater, greywater recycling, and water-scarce regions that require reliable reuse-grade output.

In January 2023, Integrated Water Services, Inc., a US-based provider of water and wastewater treatment solutions, acquired M|MBR Systems. This acquisition positions Integrated Water Services to expand market opportunities for their BluBox Modular MBR Systems, combining technology, products, and field installation to better serve customers. M|MBR Systems, a US-based bioreactor manufacturer and distributor, primarily served selected wastewater treatment and water reuse markets in the USA.
