The Toray TM700D Series reverse osmosis membranes are engineered for drinking water and brackish water purification, offering high salt rejection and exceptional chemical durability. Manufactured under ISO 9001-certified quality systems, these cross-linked aromatic polyamide composite membranes deliver long-term reliability and consistent performance for municipal, industrial, and water reuse applications.

Available in 4-inch and 8-inch element sizes, the TM700D provides 99.8% nominal salt rejection and flow rates up to 12,100 gpd (45.7 m³/d). Each element features optimized feed spacer geometry (34 mil or 28 mil) to reduce fouling and maintain stable operation under varying feed conditions. The membrane operates at pressures up to 600 psi (4.1 MPa) and temperatures up to 113°F (45°C), with wide pH compatibility (2–11 continuous, 1–13 during cleaning).

Certified to NSF/ANSI Standard 61 for potable water use, the TM700D Series meets global requirements for drinking water production and process water treatment. Offered through Total Filtration Services (TFS), the Toray TM700D delivers high-efficiency desalination, long membrane life, and dependable performance for every RO system.
