Toray Industries, Inc., announced today the launch of the TLF-400ULD reverse osmosis (RO) membrane. It developed this offering with Toray Membrane (Foshan) Co., Ltd., and Toray Advanced Materials Research Laboratories (China) Co., Ltd., for industrial wastewater reuse and sewage treatment. Toray and Toray BlueStar Membrane Co., Ltd., will market the new offering worldwide. They will showcase its potential to streamline water resource usage.

The TLF-400ULD offers several advantages over conventional counterparts. It uses Toray’s proprietary membrane manufacturing technology and flow-channel design to improve permeability and chemical resistance while maintaining high salt rejection. It slashes differential pressure increases from fouling. Toray’s innovative design doubles chemical resistance during cleaning while boosting permeability. This suppresses performance deterioration and extends service life. A clog-resistant element structure reduces fouling buildup and cuts chemical cleaning frequency. Together, these features enable stable long-term operation while consuming roughly 10% less energy. The TLF-400ULD should reduce membrane replacement frequency and simplify operational management.

Global water shortages are driving demand for water treatment technologies that handle diverse water sources, operate efficiently, and reduce environmental impact. As a next-generation solution, the TLF-400ULD will help build energy- and resource-efficient processes at water treatment sites worldwide.
China’s 14th Five-Year Plan for Circular Economy Development (2021–2025) has accelerated the adoption of water treatment membranes to combat water pollution. Toray has established an integrated structure in China covering research, development, production, and sales through Toray BlueStar Membrane, Toray Membrane (Foshan), and Toray Advanced Materials Research Laboratories (China). These companies will collaborate to deliver optimal local solutions while working with Toray’s global water treatment group.
Together, they will contribute to solving the world’s water challenges by providing advanced membrane technologies, including the TLF-400ULD, along with responsive technical services.
