Summary
Product identification
LG SW 400 R G2 Seawater Reverse Osmosis (RO) Membranes. These are next-generation LG SW G2 membranes featuring enhanced Thin Film Nanocomposite (TFN) technology.
Overview The LG SW G2 membranes offer record-breaking salt rejection, improving product quality by up to 45% compared with conventional technology, and can significantly reduce the cost of desalination. LG SW R (High Rejection) membranes combine high rejection with low energy requirements, suitable for medium to high salinity seawater applications.
Benefits
- Improved permeate quality without increasing operating pressure
- Reduced energy cost without sacrificing permeate quality
- Reduced capital and operation costs for multi-pass SWRO systems
