TM720D-400 Toray Membranes
Toray TM720D-400 High-Rejection Brackish Water RO Membrane (11,000 GPD)
The Toray TM720D-400 is a professional-grade, high-rejection brackish water reverse osmosis (RO) membrane engineered for demanding industrial water treatment, municipal drinking water, and commercial purification systems. Designed to fit standard 8-inch by 40-inch pressure vessels, this element utilizes state-of-the-art, cross-linked fully aromatic polyamide composite technology. The proprietary membrane chemistry provides enhanced chemical tolerance, ensuring high structural durability and prolonged operational life even under rigorous, continuous-duty processing conditions.
Built for maximum productivity and consistent water quality, the TM720D-400 features an expansive 400 square foot active membrane area alongside a 34-mil feed spacer that effectively mitigates pressure drops and resists internal fouling. Under standard manufacturer test conditions at 225 PSI, this heavy-duty element delivers a robust nominal permeate flow rate of 11,000 gallons per day (GPD) while maintaining an exceptional nominal salt rejection rate of 99.80%. Capable of safely withstanding a maximum operating pressure of 600 PSI, this membrane offers a reliable, high-yield filtration solution for facilities requiring the stringent removal of total dissolved solids (TDS) and other contaminants from brackish water sources.
