LG BW 400 R 10,500 GPD at 225 PSI 8 x 40 inch 99.6% Rejection Brackish Water Membranes

LG Water Solutions BW 400 R High Rejection Brackish Water RO Membrane (10,500 GPD)

The LG BW 400 R is a commercial-grade, high-rejection brackish water reverse osmosis (RO) membrane engineered by LG Water Solutions (LG Chem) to deliver proven, long-lasting reliability in demanding, high-volume water treatment systems. Utilizing LG Chem's proprietary Thin-Film Nanocomposite (TFN) technology, this standard 8-inch by 40-inch spiral-wound element is specifically designed to treat medium to high salinity feed water with exceptional efficiency. By optimizing membrane surface hydraulics and incorporating a durable 34-mil feed spacer, the LG BW 400 R offers strong resistance to fouling, extending the intervals between chemical cleanings and ensuring highly stable performance in critical heavy industrial and municipal applications.

Designed for peak continuous-duty operation, the LG BW 400 R generates a robust permeate flow rate of 10,500 GPD (39.7 m³/d) at a standard test pressure of 225 PSI. Featuring 400 square feet of active membrane area, it maintains an impressive stabilized salt rejection rate of 99.6%, effectively removing dissolved solids and providing uncompromising water purity. This highly reliable, high-volume water production makes it the ideal core component for large-scale municipal drinking water production, heavy industrial process water systems, and complex wastewater reclamation and reuse facilities.
