Global Curtain Type MBR Film Assembly Market Strategic Research Report

Scope of the Report

The global Curtain Type MBR Film Assembly market size is predicted to grow from US$ 442 million in 2025 to US$ 706 million in 2032; it is expected to grow at a CAGR of 7.1% from 2026 to 2032.

Curtain type MBR film assemblies are the core separation units of immersed membrane bioreactor systems, primarily enabling solid–liquid separation of activated sludge and water to improve effluent quality and operational stability. These assemblies typically employ curtain-style flat sheet membrane structures and operate under suction or pressure-driven filtration to generate membrane flux. The performance of curtain type MBR film assemblies in material selection, structural design, and fouling control directly impacts membrane lifespan, flux levels, energy consumption, and maintenance frequency, making them a critical determinant of overall MBR system performance and economic efficiency. Upstream, the segment includes polymer membrane materials and membrane element suppliers, midstream comprises membrane module manufacturers and system integrators, and downstream consists of municipal wastewater treatment plants, industrial parks, and water utility operators. In 2024, global sales of curtain type MBR membrane assemblies reached 20.14 million square meters, with an average unit price of USD 21.6 per square meter, an average gross profit margin of 31.8%, and an annual production capacity of 150,000 square meters per production line.

Regional Market Structure

In terms of regional distribution, the Asia-Pacific region is the core for demand and production capacity of curtain type MBR membrane assemblies, accounting for 53% of the global market, driven primarily by municipal wastewater treatment and industrial water reuse projects in China, Japan, South Korea, and Southeast Asia. Europe holds 26%, led by Germany, France, and the Netherlands, emphasizing high-end municipal reuse and industrial recycling applications. North America represents 17%, mainly driven by stringent discharge standards and upgrades to aging municipal facilities in the United States. The Middle East and other regions collectively account for 4%, with growth supported by desalination and large-scale industrial zero-liquid-discharge projects. Overall, Asia-Pacific serves as the center of market volume and growth, while Europe and North America form dual cores in technology and high-end applications.

Major Manufacturers and Industry Competition

The upstream segment of the curtain type MBR membrane assembly industry primarily consists of membrane material and key component suppliers, including high-performance polymer suppliers such as Arkema, Solvay, and SABIC, as well as manufacturers of membrane support structures, fittings, and sealing components. The midstream comprises membrane module manufacturers and system integrators responsible for module encapsulation, air/water backwash design, and automation control integration. Leading companies—including SUEZ, Xylem, Toray, Kubota, Asahi Kasei, Pentair, Nitto Denko, and Chinese domestic firms such as OriginWater, Shipu Tai, Lisheng, PE Membrane, and Tianjin Membrane—leverage material formulation optimization, modular design, and O&M services to create differentiated competitive advantages. Downstream customers include municipal wastewater treatment plants, industrial parks, and water utility operators, with long-term operation, maintenance, and membrane replacement forming a stable aftermarket.

Technology Trends and Innovation Directions

Technological development is focused on membrane material modification, flux optimization, and intelligent operation. Membrane materials are enhanced through hydrophilic modification, nanocomposites, and high-strength polymers to improve antifouling performance and lifespan. Module design optimizations include low-energy aeration, modular layouts, and high-flux structures. Intelligent operation leverages online flux monitoring, AI-based predictive cleaning, and automated backwash strategies to reduce energy consumption and improve operational stability, while modular and containerized systems facilitate rapid deployment and scalability.

Policy Support and Industry Growth Drivers

Policy support is a core driver for the development of curtain type MBR membrane assemblies. Increasingly strict wastewater discharge standards, industrial water reuse requirements, and reclaimed water policies worldwide continue to drive market growth. China has issued the “Action Plan for Urban Wastewater Treatment Upgrading” and the 14th Five-Year Plan for urban wastewater treatment and resource utilization, targeting a reuse rate of over 25% in water-scarce cities and encouraging the application of high-efficiency, energy-saving membrane technologies. Developed regions such as Europe, the United States, and Japan promote water recycling, carbon reduction, and industrial reuse through frameworks like the Water Reuse Action Plan and Reclaimed Water Guidelines. Overall, policy orientation has shifted from simple compliance with discharge standards to integrated goals of pollution reduction, carbon mitigation, improved water quality, and operational efficiency, supporting the broad adoption of curtain type MBR membrane assemblies in municipal, industrial, and agricultural water reuse projects, while raising requirements for system energy efficiency, economic performance, and long-term reliability.
