Toray Unveils Advanced TLF-400ULD RO Membrane

Toray Industries, Inc., has launched the TLF-400ULD reverse osmosis (RO) membrane, designed to enhance industrial wastewater reuse and sewage treatment. Developed in collaboration with Toray Membrane (Foshan) Co., Ltd., and Toray Advanced Materials Research Laboratories (China) Co., Ltd., the new membrane improves permeability and chemical resistance while maintaining high salt rejection. Its clog-resistant element structure and optimized flow-channel design reduce fouling, extend service life, and simplify operational management. The technology also achieves roughly 10% lower energy consumption compared with conventional membranes, supporting more sustainable water treatment operations.

The TLF-400ULD is part of Toray’s global strategy to address water scarcity and provide energy- and resource-efficient solutions at water treatment sites worldwide. The membrane’s design halves differential pressure increases from fouling, doubles chemical resistance during cleaning, and extends intervals between maintenance, helping operators maintain stable long-term performance. Toray will market the membrane globally through Toray and Toray BlueStar Membrane Co., Ltd., offering technical services and locally adapted solutions in China and other regions.

The technology is particularly relevant in the context of China’s 14th Five-Year Plan for Circular Economy Development, which encourages adoption of water treatment membranes to combat water pollution. Its combination of durability, efficiency, and reduced operational burden exemplifies next-generation membrane solutions for industrial water reuse.
