LG BW 440 UES

Summary

Product identification

LG Chem’s NanoH₂O™ LG BW 440 UES are Ultra Low Energy brackish water reverse osmosis (RO) membranes. They incorporate innovative Thin Film Nanocomposite (TFN) technology, offering superior performance with intrinsic anti-fouling properties. These membranes are suitable for low salinity brackish water applications, providing high permeability at ultra-low feed pressure to reduce operating costs.
