Global Hollow Fiber Curtain Membrane Module Market Strategic Research Report

Scope of the Report

The global Hollow Fiber Curtain Membrane Module market size is predicted to grow from US$ 499 million in 2025 to US$ 733 million in 2032; it is expected to grow at a CAGR of 5.9% from 2026 to 2032.

Hollow fiber curtain membrane modules are a type of submerged membrane separation module commonly used in wastewater treatment. They are typically made of polymer materials such as PVDF, with the membrane fibers suspended vertically, resembling a "curtain." Combining biodegradation and membrane filtration technologies, they utilize pressure difference to filter impurities, featuring strong antifouling capabilities, high flux, and a compact structure.

The upstream core lies in the supply of high-performance membrane materials, including polymer resins such as polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE), as well as reinforced braided tubing, fine chemical additives, and water collection pipe fittings. Downstream, it widely connects with large-scale municipal wastewater treatment plants and industrial wastewater reuse projects. Overall, the chemical stability of upstream materials determines the membrane's lifespan, the midstream membrane manufacturing process determines the quality of the produced water, and increasingly stringent downstream environmental emission standards are the core engine driving technological iteration across the entire industry chain.

In 2025, the global sales volume of hollow fiber curtain membrane modules will reach 22.86 million square meters, with an average unit price of US$22.3 per square meter, an average gross profit margin of 30%-35%, and an annual production capacity of 150,000 square meters per production line.

With breakthroughs in materials science, particularly the widespread adoption of reinforced lining technology, curtain membranes have overcome the drawbacks of early models, such as easy fiber breakage and rapid flux decline, becoming the preferred solution for zero-discharge (ZLD) industrial wastewater and municipal upgrading projects.

From a driving force perspective, the core impetus stems from global water scarcity and increasingly stringent environmental regulations. In particular, the significant expansion of the semiconductor, biopharmaceutical, and new energy industries has generated large quantities of complex wastewater, leading to a surge in demand for PTFE/PVDF curtain membranes with high chemical stability and anti-fouling capabilities. Simultaneously, the advancement of dual-carbon goals is forcing companies to adopt lower-energy-consumption aeration and vibration technologies, further accelerating the market penetration of energy-efficient membrane modules.
