TM820V-400 Toray 9,000 GPD at 800 PSI 8 x 40 inch 99.8% Rejection Membranes

Toray TM820V-400 Seawater RO Membrane (9,000 GPD

The Toray TM820V-400 is an advanced, low-energy reverse osmosis (RO) membrane element engineered specifically for seawater desalination and the treatment of high-salinity feed waters. Manufactured utilizing Toray’s proprietary cross-linked, fully aromatic polyamide composite technology, this 8-inch by 40-inch spiral-wound membrane delivers an exceptional balance of high permeability and robust structural durability. Its state-of-the-art membrane chemistry is designed to maximize permeate quality while significantly lowering operational energy costs, making it a premier choice for continuous-duty commercial and municipal applications, including large-scale desalination plants, industrial wastewater reclamation, and high-recovery RO systems.

Designed for seamless integration into standard 8040 commercial pressure vessels, the TM820V-400 provides a massive nominal permeate flow rate of 9,000 GPD (34.1 m³/d) with a highly consistent nominal salt rejection of 99.8%. The element features a 400 square-foot active membrane area and utilizes a 34-mil feed spacer, which effectively balances internal flow dynamics and mitigates the risk of particulate fouling in challenging water environments. Operating efficiently at a standard test pressure of 800 PSI, this membrane drastically reduces the energy consumption of high-pressure booster pumps while safely accommodating a maximum applied pressure of 1200 PSI. By combining precision-automated manufacturing with industry-leading polymer science, this RO element delivers reliable, long-lasting performance for mission-critical liquid purification.
