LG BW 400 ES is an energy-saving brackish water reverse osmosis (RO) membrane element designed for efficient and reliable water purification in industrial and municipal applications. It uses advanced Thin Film Nanocomposite (TFN) technology to deliver high permeate flow and excellent salt rejection even at low feed pressures, reducing operating costs and energy consumption. The membrane has a 400 ft² active area and typically achieves over 99.5 % salt rejection, producing high-quality permeate water for process and drinking water systems. It fits standard 8″ × 40″ housings and is ideal for treating low to medium salinity brackish water sources
