Toray started the research and development of reverse osmosis membranes in 1968, and now it produces RO, NF, UF, MF and other water treatment membranes according to different purposes, becoming a comprehensive membrane manufacturer that can develop and produce all kinds of liquid separation membranes, and these membranes have been widely used in different fields. The trademarks of RO and NF membrane products are ROMEMBRATM, UF and MF membrane products are TORAYFILTM. Dongli's membrane product business began with the manufacture of ultra-pure water in the semiconductor industry, and now it mainly focuses on seawater desalination and brackish water desalination. Especially in the field of seawater desalination, it has reached a cumulative performance of more than 54, m3/d all over the world. In addition, Dongli's various membrane products, including low-pollution RO membrane products with excellent anti-organic pollution performance, have attracted great attention from large-scale waterworks customers at home and abroad in terms of membrane applications for boiler feed water, industrial pure water and wastewater treatment and reuse.

In addition, Toray has completed the technical development of membrane bioreactor (MBR), which is regarded as the technological revolution of sewage treatment in the 21st century, and has started to put it into the China market.
