LG SW 400 SR

Summary

Product identification

LG Chem's NanoH₂O™ seawater reverse osmosis (RO) membranes, featuring innovative Thin Film Nanocomposite (TFN) technology, are designed to reduce the cost of desalination while delivering superior water quality. The LG SW SR (Super Rejection) membranes offer the highest rejection for optimal product water quality and are suitable for high salinity seawater applications.
