LG BW 440 ES

Summary

Product identification

LG Chem LG BW 440 ES are Brackish Water Reverse Osmosis (RO) Membranes. These "Energy Saving" (ES) membranes incorporate innovative Thin Film Nanocomposite (TFN) technology, offering high permeability at low feed pressure, which helps reduce operating costs. They are designed for low to medium salinity brackish water applications.
