⚓ LG Chem SW 440 R Seawater RO Membrane
The LG Chem SW 440 R is a high-rejection seawater reverse osmosis (RO) element designed for large-scale desalination systems and demanding maritime environments. Part of LG Chem’s NanoH2O™ product line, this element utilizes advanced Thin Film Nanocomposite (TFN) technology to deliver exceptional salt rejection and high permeate quality. It is specifically engineered for projects that require a high degree of reliability and the consistent removal of salinity and boron from seawater sources.
Constructed with an 8-inch diameter and an industry-leading active surface area of 440 square feet, the SW 440 R allows for high productivity while maintaining a compact system footprint. The element features a robust design that can withstand the high operating pressures typical of seawater desalination, ensuring stable long-term performance. With a stabilized salt rejection of 99.85% and a permeate flow rate of 8,200 gallons per day, it provides a cost-effective and energy-efficient solution for producing potable water from high-salinity feed sources.
