LG BW 440 ES L

    Energy Saving membrane equipped with fouling tolerant low dP feed spacer technology |

     

    LG BW 440 ES L is an energy-saving brackish water RO membrane element with high productivity. The RO element incorporates a proprietary feed spacer technology for reducing differential pressure, resulting in excellent anti-fouling properties for reduced cleaning frequency, chemical use, energy use, and total cost of plant ownership. Ideal applications include wastewater reuse, second-pass RO for seawater desalination, ultrapure water production, high-purity water, and feed water sources with low to medium salinity brackish water.
