Seawater Reverse Osmosis (SWRO)
LG SW 440 GR G2
The next-generation LG SW G2 membranes have achieved record-breaking salt rejection, improving the product quality up to 45% compared with the conventional technology. With enhanced Thin Film Nanocomposite (TFN) technology, LG SW G2 membranes can significantly reduce the cost of desalination.
LG SW SR (Super Rejection) membranes offer the highest rejection for the best product water quality; suitable for high salinity seawater applications.
LG SW G2 Benefits
- 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
