LG SW 400 SR G2

Summary

Product identification

LG SW 400 SR G2 are Seawater Reverse Osmosis (RO) Membranes. The next generation LG SW G2 membranes feature enhanced Thin Film Nanocomposite (TFN) technology, suitable for high salinity seawater applications, offering record-breaking salt rejection.

LG SW G2 Benefits 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
