TM820M-400 Toray Membranes

Toray TM820M-400 Seawater RO Membrane (7,000 GPD)

The Toray TM820M-400 is an industrial-grade, standard-energy seawater reverse osmosis (SWRO) membrane engineered for demanding desalination and high-salinity water treatment applications. Manufactured utilizing state-of-the-art, cross-linked fully aromatic polyamide composite technology, this 8-inch by 40-inch element delivers exceptional contaminant removal and robust chemical resistance for long-term structural durability. It is designed to efficiently process feed water sources with salinity concentrations exceeding 10,000 ppm, making it an optimal choice for municipal, commercial, industrial, and shipboard seawater desalination systems requiring a highly reliable supply of premium-quality permeate.

Operating with a robust 34-mil feed spacer to mitigate pressure drops and reduce fouling potential, the TM820M-400 features an expansive 400 square foot active membrane area. Under standard manufacturer test conditions, this high-performance element produces a nominal permeate flow rate of 7,000 gallons per day (GPD) at an applied pressure of 800 PSI. Alongside its impressive 99.80% nominal salt rejection rate, the membrane also achieves exceptional typical boron rejection capabilities (95% at pH 8), ensuring strict compliance with high-purity drinking water standards. Designed for continuous, high-yield duty, it can safely withstand maximum operating pressures up to 1,200 PSI, providing facility operators with an exceptionally efficient and dependable seawater filtration solution.
