LG Chem would like to announce the availability of a new anti-fouling and energy-saving reverse osmosis (RO) membrane element in their NanoH2OTM brackish water product line. The new model, part number BW 400 ES L, uses the same proven energy-saving ES membrane offered by LG Chem but now incorporates an innovative feed spacer technology for reducing differential pressure.
The novel feed spacer design, with 34-mil thickness, minimizes flow disturbance and pressure losses without increasing concentration polarization. Tests have shown that the BW 400 ES L element has up to 45% reduction in differential pressure at typical flow rates compared to RO elements with standard 34-mil feed spacers. Furthermore, the improved fouling resistance results in a 50% lower normalized permeate flow rate decrease rate, leading to fewer cleaning requirements, chemical use, and plant downtime. Lastly, combined with the energy-saving membrane, the BW 400 ES L product operates with up to 35% lower pressure loss for excellent RO plant efficiency and uptime.

The new brackish water element is ideal for treating wastewater and other feed water types with moderate fouling potential. This model is certified and listed under NSF/ANSI 61 Standard for drinking water system components. Please click here for the product page and datasheet download: Quick link.
