Description Spec Sheet / Manual Technical Specifications

LG SW 440 GR G2 NanoH2O Seawater Reverse Osmosis Membrane, 8" x 40"

LG Chem’s NanoH2O™ seawater RO membranes, incorporated with innovative Thin Film Nanocomposite (TFN) technology, reduce the cost of desalination while delivering superior water quality. Our seawater RO membranes provide industry leading salt rejection and produce 20% more flow than membranes manufactured with conventional technologies. We continue to leverage the technological advantages of our seawater RO membranes to expand our market share accruing more than 1,000 Million Liter per Day (MLD) projects backlog for the last two years.

The next generation LG SW G2 membranes have achieved record-breaking 99.89% 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 GR (Great Rejection) membranes offer a combination of high rejection and low energy requirements to reduce the total cost of desalination; 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
