China’s membrane filtration sector is becoming increasingly important as municipalities and industrial facilities seek more efficient ways to treat wastewater, recover water, and produce high-purity supplies. Reverse osmosis, ultrafiltration, nanofiltration, microfiltration, and membrane bioreactor technologies are being deployed across municipal water treatment, industrial processing, food and beverage production, pharmaceuticals, electronics, and other applications. Growing emphasis on water conservation and wastewater resource utilization is also encouraging investment in advanced membrane systems and domestic manufacturing capacity.
A comprehensive market assessment by MarkNtel Advisors reveals that the China Membrane Filtration Market was valued at USD 3.45 billion in 2025 and is projected to grow from USD 3.74 billion in 2026 to USD 6.15 billion by 2032, registering a CAGR of 8.70% during 2026–2032. The China Membrane Filtration market report covers microfiltration, ultrafiltration, nanofiltration, reverse osmosis, membrane bioreactors, polymeric, ceramic, composite and hybrid membranes, module configurations, and applications across water and wastewater, food and beverages, pharmaceuticals, and industrial processing.
Water Reuse Strengthens Membrane Demand
Water scarcity and increasing pressure to improve wastewater utilization are major factors supporting membrane filtration adoption. Membrane systems can provide advanced separation and purification capabilities, making them suitable for tertiary wastewater treatment, industrial water reuse, and high-purity applications.
China’s policy framework is also encouraging wastewater resource utilization. The National Development and Reform Commission, Ministry of Housing and Urban-Rural Development, and Ministry of Ecology and Environment have targeted greater reclaimed-water use in water-scarce cities and promoted industrial wastewater recycling. These policies are creating opportunities for membrane-based tertiary treatment, recycling systems, and advanced purification infrastructure.
Polymeric Membranes Maintain Leadership
Polymeric membranes represent the dominant membrane-material segment, accounting for approximately 75% of the market in 2026. Their relatively low production cost, scalability, flexibility, and established use across municipal and industrial applications support their strong position.
Materials such as polyethersulfone, polyvinylidene fluoride, and polysulfone are widely used in membrane manufacturing. Their versatility enables application across different filtration processes and module configurations.
China's domestic manufacturing capabilities are also strengthening the supply base. Beijing OriginWater Technology has disclosed annual production capacity of approximately 10 million square meters of MF/UF membranes, demonstrating the scale of local membrane manufacturing.
Reverse Osmosis Leads Technology Adoption
Reverse osmosis represents the leading technology segment, accounting for approximately 38% of the market in 2026. RO systems can remove dissolved salts, heavy metals, microorganisms, and other contaminants, making them particularly valuable for drinking-water purification, industrial water reuse, desalination, and high-purity water production.
The technology is also gaining importance in advanced manufacturing, where stringent water-quality requirements require multiple purification stages.
China's expanding water-reuse infrastructure and industrial modernization are therefore creating opportunities for higher-performance RO membranes with improved recovery, contaminant rejection, and resistance to fouling.
Semiconductor Expansion Creates High-Purity Water Demand
China's growing semiconductor industry is creating a specialized application for membrane filtration technologies. Semiconductor manufacturing requires high-purity water with tightly controlled contaminant levels, while facilities are increasingly seeking opportunities to recycle water generated during manufacturing.
The Ministry of Industry and Information Technology reported that China's integrated-circuit production reached 451.4 billion units in 2024, representing a 22.2% year-on-year increase.
The expansion of semiconductor capacity is consequently supporting demand for RO, ultrafiltration, and complementary purification technologies.
In 2024, Toray Industries introduced its TBW-XHR reverse osmosis membrane elements for ultrapure-water production from reclaimed wastewater used in semiconductor manufacturing. The product achieved approximately 90% urea removal in internal evaluations, highlighting the industry's focus on specialized membrane solutions.
Municipal Wastewater Modernization Expands Opportunities
Municipal wastewater treatment is another important application area. China's urbanization and environmental objectives are encouraging cities to expand treatment capacity, improve collection networks, and increase reclaimed-water production.
The national wastewater resource-utilization framework calls for expanded sewage-treatment infrastructure and greater reclaimed-water use, creating opportunities for membrane bioreactors, ultrafiltration, and reverse osmosis systems.
The NDRC has also highlighted examples of wastewater facilities using advanced treatment and intelligent control to improve treatment efficiency and reduce energy and material consumption.
These developments reinforce the transition from conventional wastewater disposal toward resource recovery and reuse.
Fouling Remains a Technology Challenge
Membrane fouling continues to be one of the most important operational challenges. Suspended solids, microorganisms, organic matter, and inorganic scaling can accumulate on membrane surfaces, reducing permeate flow and increasing cleaning and maintenance requirements.
The challenge is encouraging manufacturers to develop fouling-resistant membranes, improved pretreatment systems, optimized cleaning processes, and digital monitoring technologies.
Advanced membrane designs can potentially extend operating periods between cleaning cycles while maintaining treatment performance. This can help reduce lifecycle costs and improve reliability for large municipal and industrial installations.
Digital Tools Improve System Design
Digitalization is becoming increasingly relevant to membrane-system engineering. Simulation and modeling platforms can help engineers evaluate membrane configurations, water chemistry, operating conditions, energy requirements, and expected performance before physical installation.
In March 2025, DuPont Water Solutions launched WAVE PRO, a digital modeling platform for ultrafiltration applications including municipal drinking water, industrial water, wastewater reuse, and desalination.
Such tools can support more efficient system design and help operators evaluate alternative configurations before committing to capital-intensive installations.
Competitive Landscape
The China membrane filtration market remains highly fragmented, with the top five companies collectively accounting for approximately 23% of revenue in 2026. Competition centers on membrane performance, domestic manufacturing capabilities, R&D investment, application expertise, project execution, and long-term customer relationships.
Key companies identified in the study include DuPont Water Solutions, Toray Industries, Inc., Hydranautics, SUEZ Water Technologies & Solutions, Veolia Water Technologies, Koch Separation Solutions, Pall Corporation, Pentair plc, Beijing OriginWater Technology Co., Ltd., and Vontron Technology Co., Ltd.
Outlook for China Membrane Filtration
China's membrane filtration sector is moving toward advanced wastewater reuse, high-purity water production, fouling-resistant membranes, digital system design, and increasingly localized manufacturing. Reverse osmosis will remain central to advanced purification, while polymeric membranes are expected to retain their strong material position.
Semiconductor expansion, municipal wastewater modernization, industrial recycling, and national water-conservation policies will continue creating opportunities. As China increasingly treats wastewater as a recoverable resource rather than simply a disposal stream, membrane filtration is positioned to play a central role in water security, industrial efficiency, and sustainable water reuse.
