Summary
Product identification
The TSW-LE Series consists of Super Low-Energy Sea Water Reverse Osmosis (RO) Membrane Elements. Toray's membrane technology incorporates decades of R&D and precision automated manufacturing under ISO 9001. These elements feature state-of-the-art cross-linked fully aromatic polyamide composite membranes, designed for high-quality permeate and robust membrane chemistry for improved performance and longer membrane life.
Products manufactured at Toray's U.S. facility (TMUS) are certified to NSF/ANSI 61 for drinking water applications.
Applications:
- Seawater desalination
- High salinity feed water
- Industrial wastewater
- High recovery RO systems
Operating limits
- Maximum operating pressure⁶: 1,200 psi (8.3 MPa)
- Maximum feed water temperature: 113 °F (45 °C)
- Maximum feed water SDI₁₅: 5
- Feed water chlorine concentration: Not detectable (ppm)
- Feed water pH range:
- Continuous operation: 2–11
- Chemical cleaning: 1–12
- Maximum pressure drop per element: 15 psi (0.10 MPa)
- Maximum pressure drop per vessel: 50 psi (0.34 MPa)
Note: All RO elements are wet tested and treated with a 1 percent by weight sodium bisulfite storage solution. Toray recommends flushing RO elements for 30 to 60 minutes once every two days with sufficient quality flushing water to prevent biological growth during system shutdown. The presence of free chlorine and other oxidizing agents can cause oxidation of the membrane; Toray strongly recommends removing these agents. Permeate from the first hour of operation shall be discarded.
