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.

Toray's reverse osmosis membrane technology applies decades of R&D and precision automated manufacturing under ISO 9001 for consistency in product quality. State-of-the-art cross-linked fully aromatic polyamide composite membranes produce high-quality permeate and robust membrane chemistry for improved performance and longer membrane life.

Reverse osmosis is the process of applying a pressure greater than the osmotic pressure of the solution on the side of the concentrated solution, forcing the water molecules to enter the dilute solution through the semi-permeable membrane in the reverse direction (opposite to the direction of natural osmosis). The semipermeable membrane flows to dilute solutions, while most of the solutes (dissolved solids) cannot pass through the membrane and are trapped.
