LG SW 440 R 9,900 GPD at 800 PSI 8 x 40 inch Membranes

LG Water Solutions LG SW 440 R Seawater RO Membrane (9,900 GPD)

The LG SW 440 R is a premium, high-rejection Seawater Reverse Osmosis (SWRO) membrane element engineered for large-scale desalination systems and demanding maritime environments. Manufactured by LG Water Solutions (a division of LG Chem) as part of their renowned NanoH2O™ product line, this 8-inch by 40-inch spiral-wound element utilizes advanced Thin Film Nanocomposite (TFN) technology. This proprietary construction embeds benign nanomaterials into the polyamide layer, delivering exceptional salt rejection and high permeate quality without compromising flux. It is specifically engineered for high-demand municipal and industrial projects that require unwavering reliability and the consistent removal of high salinity and boron from harsh seawater sources.

Constructed with an industry-leading active surface area of 440 square feet, the LG SW 440 R enables maximum productivity while maintaining a standard, compact 8040 system footprint. Designed to safely withstand the severe operating pressures typical of seawater desalination, this robust element produces a massive nominal permeate flow rate of 9,900 gallons per day (GPD). Evaluated under standard test conditions at an applied pressure of 800 PSI, it delivers a superior stabilized salt rejection rate of 99.85%. By balancing expansive membrane area with cutting-edge nanocomposite technology, it provides a highly cost-effective and energy-efficient solution for producing premium potable water from challenging, high-salinity feed sources.
