LG SW 440 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 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 the highest salt rejection with high freshwater productivity.

Each LG SW 440 R membrane element is supplied with one membrane interconnector.
