LG BW 2521 UES

Summary

Product identification

The LG BW 2521 UES is an Ultra Low Energy brackish water Reverse Osmosis (RO) membrane element, featuring Thin Film Nanocomposite (TFN) technology. It is designed for various municipal and industrial applications, especially suitable for low salinity brackish water where high permeability at ultra-low feed pressure is desired to reduce operating costs.
