TORAY began producing spiral-wound reverse osmosis and nanofiltration membrane elements in 1968, first using cellulose acetate membrane material. Today, our product line includes a full range of state-of-the-art cross-linked polyamide composite membranes manufactured under ISO-9001 certification for consistency in product and service quality.

Nanofiltration (NF) is used to separate substances with relatively small molecular weights, such as inorganic salts or small molecular organics such as glucose and sucrose, from solvents. Nanofiltration, also known as low-pressure reverse osmosis, is an emerging field of membrane separation technology. Its separation performance is between reverse osmosis and ultrafiltration, allowing some inorganic salts and some solvents to pass through the membrane to achieve separation.
