LG BW 4040 UES (Ultra Low Energy Brackish Water RO)
Product Description
The LG BW 4040 UES is an Ultra Energy Saving (UES) Brackish Water Reverse Osmosis (RO) element, developed by LG Chem to achieve high flux at extremely low pressures. Utilizing LG's innovative NanoH2O™ Thin-Film Nanocomposite (TFN) technology, this 4-inch diameter by 40-inch long element delivers exceptional permeate flow while significantly reducing energy consumption. The BW 4040 UES is rated for a nominal flow rate of 2,700 GPD at an impressively low test pressure of just 100 PSI. This element maintains a reliable stabilized salt rejection of 99.6%. It is the ideal choice for light commercial RO systems, small bottling operations, and any application where feed water TDS is low and the primary focus is minimizing operational and energy costs.
