LG SW 440 R

Summary

Product identification

The LG SW 440 R is a seawater reverse osmosis (RO) membrane from LG Chem's NanoH2O™ product line, featuring innovative Thin Film Nanocomposite (TFN) technology. These membranes are designed to reduce desalination costs, deliver superior water quality, and provide industry-leading salt rejection. They offer 20% more flow compared to conventional technologies.

The LG SW R (High Rejection) membranes combine high rejection with low energy requirements, making them suitable for medium to high salinity seawater applications.
