Ultrapermeable membranes (UPMs) have the potential of improving water production efficiency. However, operating at high water fluxes will intensify concentration polarization and membrane fouling. Inspired by the V-formation of birds in nature we propose a transformative membrane module that enables a doubled mass transfer coefficient with a moderately increased friction loss coefficient. Moreover, we present a practical technological pathway for the UPM systems to achieve 338% improvement of average water flux and 18% energy savings relative to state-of-the-art seawater desalination plants. The work makes it practical to operate at a high average water flux of 84 L m⁻² h⁻¹ with a controlled concentration polarization for the UPM systems. It breaks through the module development bottlenecks for the next-generation UPM systems and has enormous potential application for alleviating water scarcity crisis in the coming decades.

超透膜（UPM）具有提高产水效率的潜力。然而，在高水通量下运行会加剧浓差极化和膜污染。受自然界鸟类 V 形结构的启发，我们提出了一种变革性的膜组件，该组件可以使传质系数加倍，并适度增加摩擦损失系数。此外，我们还为 UPM 系统提出了一条实用的技术途径，相对于最先进的海水淡化厂，平均水通量提高了 338%，节能 18%。这项工作使得UPM 系统可以在 84 L m ^-2  h ^{-1的高平均水通量下运行，并具有受控的浓差极化。}它突破了下一代UPM系统的模块开发瓶颈，对于缓解未来几十年的水资源短缺危机具有巨大的应用潜力。
