LG BW 2540 UES

Summary

Product identification

LG Chem's NanoH2O™ LG BW 2540 UES is an Ultra Low Energy brackish water Reverse Osmosis (RO) membrane. It incorporates Thin Film Nanocomposite (TFN) technology, offering superior performance with intrinsic anti-fouling properties. These membranes provide high permeability at ultra-low feed pressure, significantly reducing operating costs, making them suitable for low salinity brackish water applications.
