Membrane Bioreactor (MBR) Market size was estimated at USD 3.98 Billion in 2024 and is expected to reach USD 9.56 Billion by 2035, growing at a CAGR of 10.45% during the forecast period of 2025-2035.
A Membrane Bioreactor or MBR is a technology that integrates membrane filtration with biological treatment of wastewater. It comprises a bioreactor in which the pollutants are decomposed by microorganisms, and a membrane module that segregates treated water from biomass with the passage of pure water.
MBR technology is used extensively in municipal and industrial wastewater treatment because it is highly efficient and has a small footprint.
It is used in processes where tight discharge specifications are needed, e.g., for the treatment of sewage, industrial effluent, and food and beverage processing wastewater.
MBR processes are also used in water re-use schemes, offering high-quality effluent that can be reused for irrigation, industrial purposes, or even drinking purposes after further treatment

North America
North America is leading the Membrane Bioreactor (MBR) market. There is widespread adoption of advanced technologies and innovations in wastewater treatment due to robust research and development activities and a concern for improving operational efficiency. The U.S. Environmental Protection Agency (EPA) has established stringent water quality standards under the Clean Water Act. For instance, the National Pollutant Discharge Elimination System (NPDES) permit program regulates point sources that release pollutants into U.S. waters.
Heavy investments are provided for wastewater treatment projects and infrastructure by both public and private sources. This also involves investment in the upgrade of existing plants and the creation of new projects using MBR technology. The Water Environment Research Foundation (WERF) in the United States has sponsored several MBR technology-related projects. For example, they supported a project on “Membrane Bioreactor Process Optimization” in 2022.
Stricter environmental regulations and policies to ensure better water quality and sustainable approaches drive the deployment of sophisticated treatment technologies such as MBRs. For example, Koch Separation Solutions released a new MBR product platform in January 2024 centered on modular technology for simpler installation and maintenance within municipal and industrial applications.
Asia Pacific
Asia-Pacific is seeing high growth within the MBR market. The Asia-Pacific MBR market, which was worth USD 1.2 Billion in 2023, is anticipated to grow to USD 2.1 Billion by 2028, with a CAGR of 11.8%, a notable rise above the global average., fueled by growing urbanization, industrialization, and water scarcity in nations like China, India, and Japan. The 14th Five-Year Plan (2021-2025) aimed at enhancing the wastewater treatment rate to 95% in urban regions and 40% in rural regions by 2025.
Government initiatives towards wastewater management, increased industrial activities, and investments in the development of infrastructure are the prominent drivers propelling the growth of the MBR market in the region. For example, Mitsubishi Electric released in January 2024 a new MBR system that is optimized for decentralized treatment of wastewater in rural areas in developing Asian countries.
