Toray's new membrane for industrial wastewater reuse and sewage treatment
Toray industries launches the TLF-400ULD reverse osmosis (RO) membrane for industrial wastewater reuse and sewage treatment. This offering was developed with Toray Membrane (Foshan) Co., Ltd., and Toray Advanced Materials Research Laboratories (China) Co., Ltd.

Toray launches reverse osmosis membrane for industrial wastewater reuse and sewage treatment.
The TLF-400ULD offers several advantages over conventional counterparts. It uses Toray’s proprietary membrane manufacturing technology and flow-channel design to improve around 10% higher 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.
Toray and Toray BlueStar Membrane Co., Ltd., will market the new offering worldwide. They will showcase its potential to streamline water resource usage.
