LG BW 400 ES

Summary

Product Identification

LG Chem's NanoH₂O™ LG BW 400 ES Brackish Water Reverse Osmosis (RO) Membranes are designed for energy saving. They incorporate innovative Thin Film Nanocomposite (TFN) technology, providing superior performance and intrinsic anti-fouling properties. These membranes offer high permeability at low feed pressure, reducing operating costs, and are suitable for low to medium salinity brackish water applications.
