The membrane bioreactor market has seen considerable growth due to a variety of factors.
• The market size for membrane bioreactors has seen a swift expansion in the past few years. The market value is projected to escalate from $4.24 billion in 2024 to $4.72 billion in 2025, with a compound annual growth rate (CAGR) of 11.4%.
The notable growth in the preceding period can be credited to increasing water shortage and the escalating demand for water recycling, population influx, and urbanization, leading to amplified wastewater generation. Other contributing factors include the focus on energy conservation and reduction of chemical usage in treatment facilities, the necessity for compact and efficient wastewater treatment solutions, and government schemes with funding for high-end water treatment technologies.
The membrane bioreactor market is expected to maintain its strong growth trajectory in upcoming years.
• The size of the membrane bioreactor market is predicted to experience swift expansion in the coming years. It is projected to reach $7.5 billion by 2029, with a compound annual growth rate (CAGR) of 12.2%.
The predicted expansion during the forecast period is due to the increased usage of membrane bioreactors in industrial wastewater treatment, incorporation of artificial intelligence (ai) and automation in mbr systems, appeal for advanced processes for nutrient removal and resource recovery, widened application of mbr technology in desalination and water purification, and emphasis on decentralized wastewater treatment systems. Key trends during the forecast period include integration of anaerobic digestion with membrane technology, focus on zero liquid discharge (zld) solutions, advancements in the design of membrane materials and modules, utilization of hollow fiber membranes in mbr systems, and hybrid systems that incorporate advanced oxidation processes (aops).

The escalating issues of water contamination are playing a substantial role in the expansion of the membrane bioreactor market. Water contamination happens when harmful substances, often chemicals or microbes, are released into water bodies such as streams, rivers, lakes, or oceans. This problem is heightened due to the lack of safe, clean, and drinkable water sources. Membrane bioreactors have therefore become a feasible solution for water treatment through microfiltration or ultrafiltration, given the mounting water pollution concerns. For instance, the World Health Organization, a Switzerland-based intergovernmental organization, stated in September 2023 that in 2022 there were 2.2 billion people without access to properly managed water services, while 1.5 billion had basic services with improved water sources, reachable within a 30-minute round trip. Furthermore, 292 million had limited services, requiring more than 30 minutes to collect water, 296 million used unprotected wells and springs, and 115 million obtained raw surface water from lakes, ponds, rivers, and streams. Therefore, the increase in water pollution is predicted to stimulate demand, driving growth for membrane bioreactors within the forecast period.

Innovations in technology are becoming increasingly prevalent as a major trend in the membrane bioreactor market. Companies dominating this sector are emphasizing on providing technologically-driven water treatment solutions to solidify their standing in the market. These firms incorporate cutting-edge technological structures into their solutions, which includes microfiltration, ultrafiltration, rotating biological contactor, aeration technology, mechanical filtration, among other techniques that facilitate superior removal of organic and suspended solids. For example, in March 2022, Toray Industries from Japan, a firm providing water treatment membranes and technical services, released the TBW-HR series of ultra-low-pressure reverse osmosis membrane elements, offering enhanced neutral molecule rejection. By regulating the micropore sizes and structures of RO membranes, these novel products remarkably enhance the rejection of silica, boron, and other neutral molecules found in untreated water.
