LG Chem Water Solutions

LG Chem manufactures the full line of NanoH2O™ seawater and brackish waterreverse osmosis (RO) membranes based on innovative Thin Film Nanocomposite(TFN) technology. They are constantly evolving and have had great success in winninglarge desalination projects and continue to strengthen market leadershipfor seawater RO.

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. LG Chem’s seawater RO membranes provide industry leading salt rejection and produce 20% more flow than membranes manufactured with conventional technologies.

Developed from the essence of innovative Thin Film Nanocomposite (TFN) technology, LG BW R G2 RO membranes provide excellent permeate water quality while reducing energy consumption. Equipped with anti-fouling low dP spacer technology, LG BW 400 R G2 reduces cleaning frequency and expands membrane life span. LG BW R G2 has achieved further improvement from LG BW R, which is in high demand globally. With excellent chemical durability, LG BW R G2 demonstrates stable performance and longer product life even under harsh chemical cleaning. LG BW R G2 is the most versatile BWRO membranes LG Chem offers up to date.

LG Chem’s NanoH2O™ brackish water RO membranes serve various municipal and industrial applications and have been operating in the major utilities around the world.
LG BWRO membranes, all incorporated with innovative Thin Film Nanocomposite (TFN) technology, are offered in industry standard configurations and can easily fit into existing and new RO plants.
