LG SW 440 SR

Summary

Product Identification

LG Chem's NanoH2O™ LG SW 440 SR is a seawater reverse osmosis (RO) membrane. It incorporates innovative Thin Film Nanocomposite (TFN) technology, designed to reduce desalination costs and deliver superior water quality. These "Super Rejection" (SR) membranes are characterized by high salt rejection, suitable for high salinity seawater applications, and reportedly produce 20% more flow than membranes using conventional technologies.
