Seawater Reverse Osmosis (SWRO)
LG SW 440 R 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 R (High Rejection) membranes offer a combination of high rejection and low energy requirements to reduce the total cost of desalination; suitable for medium to 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
