LG SW 440 SR G2

Summary

Product identification

LG SW 440 SR G2 is a seawater reverse osmosis (RO) membrane. These LG SW G2 membranes utilize enhanced Thin Film Nanocomposite (TFN) technology, suitable for high salinity seawater applications.

Key benefits of LG SW G2 membranes include:

• Improved permeate quality without increasing operating pressure
• Reduced energy cost without sacrificing the permeate quality
• Reduced capital and operation costs for multi-pass SWRO systems
