LG SW 440 R G2

Summary

Product identification

The LG SW 440 R G2 is a Seawater Reverse Osmosis (RO) Membrane. These LG SW G2 membranes utilize enhanced Thin Film Nanocomposite (TFN) technology. LG SW R (High Rejection) membranes are designed to offer a combination of high rejection and low energy requirements, making them suitable for medium to high salinity seawater applications.
