LG SW 4040 R (Seawater RO Membrane)
Product Description
The LG SW 4040 R is a robust and high-rejection Seawater Reverse Osmosis (SWRO) element, developed using LG Chem's innovative NanoH2O™ thin-film nanocomposite (TFN) technology. This 4-inch diameter by 40-inch long element provides exceptional performance for converting high-salinity seawater into potable water. The unique TFN structure offers superior salt rejection and consistent flow stability even under challenging feed conditions. The SW 4040 R features a flow rate of 2,100 GPD at the standard test pressure of 800 PSI. This element is a reliable and highly efficient choice for small-to-medium scale SWRO systems, including marine applications and coastal desalination plants, where maximum water quality and operational durability are essential.
