TM820V-440 Toray 9,900 GPD at 800 PSI 8 x 40 inch Membranes

Toray TM820V-440 Low Energy Seawater RO Membrane (9,900 GPD)

The Toray TM820V-440 is a high-performance, low-energy Seawater Reverse Osmosis (SWRO) membrane element engineered for maximum productivity in large-scale municipal, industrial, and marine desalination applications. Manufactured utilizing Toray's advanced cross-linked fully aromatic polyamide composite technology, this 8-inch by 40-inch spiral-wound element offers an expansive 440 square feet of active membrane area. This exceptional surface area enables the element to produce exceptionally high yields of potable water while maintaining lower feed pressure requirements, significantly reducing the overall energy consumption of high-capacity desalination plants.

Designed to handle continuous-duty operation in demanding, high-salinity environments, the TM820V-440 features a 28-mil feed spacer and a robust fiberglass-wrapped exterior for superior structural integrity. Evaluated under stringent standard test conditions at an applied pressure of 800 PSI (with a heavy 32,000 ppm NaCl feed solution), this premium element produces a massive nominal permeate flow rate of 9,900 gallons per day (GPD) while delivering an outstanding 99.8% nominal salt rejection rate. Rated to safely accommodate a maximum operating pressure of 1,200 PSI, it provides the steadfast hydraulic durability and stringent water purity necessary for mega desalination facilities, offshore platforms, and heavy-duty coastal water treatment arrays.
