LG Water Solutions BW 4040 R Brackish Water RO Membrane

 

The LG BW 4040 R is a premium, high-rejection Brackish Water Reverse Osmosis (BWRO) Membrane engineered for demanding commercial and light industrial applications. Utilizing LG Chem's proprietary Thin Film Nanocomposite (TFN) technology, this 4" x 40" element embeds benign nanomaterials into the polyamide layer to significantly enhance permeability without compromising salt rejection. It is specifically designed to treat high-salinity brackish water sources and wastewater reuse applications, delivering an outstanding 99.6% stabilized salt rejection rate.

Constructed with a highly durable hard shell fiberglass exterior to withstand elevated pressure drops, the BW 4040 R provides consistent, long-lasting performance in multi-element housings. It features a standard 28 mil feed spacer and generates a reliable permeate flow rate of 2,500 GPD when operating at a standard test pressure of 225 PSI. By matching industry-standard flux and rejection parameters, this element ensures a seamless integration into existing commercial water treatment facilities requiring high-purity permeate and uncompromising reliability.
