China Membrane Bioreactor Market to Reach USD 876.5 Million by 2032, Growing at a CAGR of 7.32% During 2026–2032

The China membrane bioreactor market was valued at USD 528 million in 2025 and is projected to grow from USD 573.8 million in 2026 to USD 876.5 million by 2032, exhibiting a CAGR of 7.32% during the forecast period. Market expansion is being strongly supported by China’s tightening wastewater discharge regulations, accelerating water reuse targets, and sustained public investment in advanced sewage treatment infrastructure. Membrane bioreactor (MBR) technology is increasingly being deployed across municipal and industrial facilities because of its ability to consistently achieve high-quality effluent standards required for reclaimed water reuse applications.

China continues to represent one of the most active deployment environments for membrane bioreactor technology globally, due to severe freshwater stress and rising urban wastewater generation. The country holds nearly 6% of global freshwater reserves while supporting more than 18% of the global population, creating long-term pressure on wastewater recycling and water conservation infrastructure. Furthermore, the 14th Five-Year Plan for Urban Wastewater Treatment and Resource Utilization established mandatory sewage treatment and reclaimed water utilization targets across water-deficient cities, significantly strengthening procurement demand for advanced membrane-based wastewater treatment systems.

Additionally, large-scale government investment programs continue to accelerate market growth across both municipal and industrial applications. China invested approximately USD 187.8 billion in water conservancy facility construction during 2024 alone as part of a broader long-term infrastructure modernization framework. In parallel, tightening zero-liquid-discharge and near-zero-effluent mandates across chemical, petrochemical, textile, and pharmaceutical industries are reinforcing adoption of advanced biological membrane treatment systems capable of supporting industrial water recycling and closed-loop reuse infrastructure. These regulations are increasing demand for submerged MBR configurations due to their lower energy intensity, compact design, and ability to reduce sludge generation compared to conventional activated sludge processes.

Submerged MBR systems dominated the China membrane bioreactor market, supported by strong municipal deployment and ongoing domestic innovation in hollow-fiber PVDF membrane technologies. Municipal wastewater treatment remained the leading application segment, accounting for 69% of market revenue, driven by mandatory Class 1A effluent discharge standards and expanding urban sewage treatment infrastructure.

Regionally, East China leads the industry with 45% shares, supported by dense industrialization, large-scale wastewater treatment modernization projects, and increasing reclaimed water reuse investments across Jiangsu, Zhejiang, Shanghai, and surrounding coastal provinces. Moreover, the competitive landscape remains highly consolidated, with the top five companies accounting for approximately 52% of total market revenue in 2025 through strong municipal project pipelines, localized membrane manufacturing, and advanced wastewater treatment expertise, as stated in the recent report, “China Membrane Bioreactor Market Analysis, 2026”.
