China's wastewater-treatment infrastructure is increasingly moving toward advanced biological and membrane-based technologies as water scarcity, urbanization, industrial activity, and demand for reclaimed water reshape treatment requirements. Membrane bioreactor (MBR) systems combine biological treatment with membrane filtration, enabling facilities to produce consistently treated effluent while using comparatively compact footprints. This makes MBR technology relevant to municipal wastewater facilities, industrial parks, and water-reuse projects.
Insights published by MarkNtel Advisors indicate that the China Membrane Bioreactor Industry reached USD 528 million in 2025 and is projected to grow from USD 573.8 million in 2026 to USD 876.5 million by 2032, registering a CAGR of 7.32% during 2026–2032. The China membrane bioreactor market report highlights water scarcity, municipal wastewater-treatment expansion, reclaimed-water utilization, industrial wastewater recycling, and technological development as major factors supporting the industry's growth.
Water Reuse Strengthens MBR Adoption
Water reuse is becoming an important part of China's approach to managing water resources. The country's policy framework encourages treated wastewater to be reused for industrial production, municipal applications, ecological restoration, agricultural irrigation, and other appropriate purposes.
China's National Development and Reform Commission has emphasized wastewater resource utilization as a way to increase available water resources while reducing pollution and environmental pressure. Its national wastewater resource-utilization guidance specifically promotes reclaimed water use in water-deficient regions and encourages advanced treatment technologies and demonstration projects.
This policy direction creates opportunities for MBR systems because membrane filtration can provide a high-quality treatment stage within wastewater-reuse configurations. Facilities can subsequently apply additional treatment depending on the intended reuse application.
Municipal Wastewater Remains the Leading Application
Municipal wastewater treatment accounts for approximately 69% of China's MBR industry in 2026, making it the largest application segment. Continued urban development is increasing wastewater volumes while treatment facilities are being upgraded to meet more demanding quality and reuse requirements.
The importance of municipal reuse is becoming increasingly visible. Chinese cities used more than 22 billion cubic meters of recycled water in 2025, with reclaimed water increasingly serving as a supplementary urban water source, according to information from China's Ministry of Housing and Urban-Rural Development. The latest national recycled-water utilization update also highlights continued investment in recycled-water facilities.
MBR technology can support this transition by combining biological treatment and membrane separation within a single treatment configuration.
Submerged Systems Maintain a Strong Position
Submerged MBR systems account for approximately 81% of China's industry in 2026, making them the dominant system configuration. In submerged systems, membrane modules are placed directly within the biological reactor, integrating biological treatment and membrane filtration into a relatively compact arrangement.
This configuration can be particularly useful for urban treatment facilities where available land is limited. It can also provide stable separation performance while reducing reliance on separate clarification stages.
China's domestic technology ecosystem is also contributing to MBR development. The National Development and Reform Commission's recent catalog of advanced technologies includes a low-carbon, high-efficiency vibrating MBR technology, demonstrating continued domestic attention toward reducing membrane-system energy consumption while improving nutrient removal.
Industrial Wastewater Creates New Opportunities
Industrial activity is creating another important application base for MBR systems. Chemical, pharmaceutical, textile, food and beverage, petrochemical, electronics, and other manufacturing facilities generate wastewater streams that can require advanced biological treatment and water-recycling solutions.
China's wastewater-resource policies specifically encourage industrial sectors with high water consumption to increase the use of reclaimed water. The national framework identifies industries including thermal power, petrochemicals, steel, non-ferrous metals, paper, and textile printing as areas where wastewater reuse can help reduce demand for freshwater.
MBR systems can therefore become part of larger industrial water-reuse trains, particularly when facilities require consistent effluent quality before downstream membrane polishing or reuse.
East China Leads Regional Demand
East China accounts for approximately 45% of China's MBR industry in 2026, representing the largest regional share. The region's extensive industrial base and dense urban development create substantial demand for advanced wastewater treatment.
Jiangsu, Zhejiang, Shanghai, Shandong, Anhui, and Fujian contain major manufacturing and industrial clusters. Chemical processing, textiles, pharmaceuticals, electronics, food production, and other industries generate diverse wastewater streams, while municipal facilities in highly urbanized areas require continuous treatment capacity.
Industrial parks are also becoming important deployment locations because centralized treatment and recycling systems can serve multiple manufacturers while supporting regional water-management objectives.
Energy Efficiency Becomes a Key Priority
Energy consumption remains one of the major considerations associated with MBR deployment. Aeration, membrane scouring, pumping, and fouling management can contribute significantly to operating costs.
China's national wastewater policy is increasingly linking pollution reduction with carbon reduction. The national guidance on reducing emissions and improving efficiency in wastewater treatment promotes energy-saving treatment processes, renewable-energy use, wastewater resource recovery, and improved overall treatment efficiency.
This is encouraging technology providers to develop lower-energy membrane configurations, improved aeration systems, and process-control technologies capable of maintaining treatment performance with reduced power requirements.
Smart Monitoring Improves System Performance
Digital technologies are also becoming increasingly relevant to MBR operations. Sensors and automated monitoring systems can track membrane pressure, flow rates, aeration conditions, fouling behavior, and other operating parameters.
These capabilities can help operators identify performance changes earlier and optimize cleaning and maintenance schedules. For large municipal facilities and industrial wastewater plants, improved monitoring can also support more consistent operation and help reduce unnecessary energy consumption.
The development of AI-assisted process monitoring further supports the industry's shift toward data-driven wastewater treatment. As MBR facilities become larger and more technically complex, digital controls can help operators manage performance more efficiently.
Resource Recovery Broadens the Role of MBRs
China is increasingly treating wastewater as a potential resource rather than solely as a waste stream. National policy promotes reclaimed-water use, industrial recycling, ecological applications, and other forms of resource recovery.
The National Development and Reform Commission has also emphasized wastewater resource utilization as part of water-resource management, linking treatment with efforts to address water shortages and environmental pressures.
This approach can strengthen the role of MBR systems within integrated treatment facilities, particularly where high-quality effluent is required for subsequent reuse or advanced treatment.
China's MBR Industry Moves Toward Efficient Water Reuse
China's membrane bioreactor industry is being shaped by water scarcity, urbanization, municipal treatment investment, industrial wastewater recycling, reclaimed-water utilization, and advances in low-energy membrane technology. Municipal wastewater treatment remains the leading application, while submerged configurations continue to dominate system deployment.
East China's industrial concentration provides a strong demand base, while energy consumption and membrane fouling remain important areas for technological improvement. As China expands wastewater reuse and strengthens its focus on efficient water-resource management, MBR technology is increasingly positioned as a key component of advanced treatment systems designed to support water recovery, environmental protection, and more sustainable urban and industrial development.
