LG Chem Reverse Osmosis Membranes Water Solutions
LG Chem NanoH2O Seawater Reverse Osmosis (SWRO) Membranes

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 seawater RO membranes provide high salt rejection and produce 20% more flow than membranes manufactured with conventional technologies.

Applied Membranes, Inc. is a master distributor of LG Chem seawater membranes, with many models in stock for immediate shipment.  LG SWRO membranes purchased from AMI are backed by the technical expertise and support of our staff of experienced water quality technicians. Contact us today for a quotation and to discuss your water treatment challenges.
