LGModel BW 400 UES -Brackish Water Reverse Osmosis Membrane (BWRO)

SHARE

Ultra low energy membrane equipped with fouling tolerant low dP spacer technology | LG BW 400 UES membrane elements deliver high permeability at very low feed pressures for ultra-low energy savings. The RO element also 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 brackish feed water with low salinity.
