LG  BW400 ES L

    Energy Saving

    Equipped with fouling tolerant low dP spacer technology |


    LG BW 400 ES L is highly permeable at low feed pressure and incorporates a unique proprietary feed spacer technology for reducing differential pressure. The results are excellent anti-fouling properties and lower cleaning frequency, chemical use, energy consumption, and total cost of plant ownership. Ideal applications include feed water sources with low to medium salinity brackish water.
