LG BW 440 R Dura

Summary

Product identification

LG Chem’s NanoH₂O™ brackish water RO membranes, specifically the LG BW 440 R Dura, offer high rejection and high durability. They incorporate Thin Film Nanocomposite (TFN) technology for superior performance and intrinsic anti-fouling properties, suitable for high salinity brackish water and wastewater reuse applications with challenging feed water conditions.
