LFC (Low Fouling Composite) membranes combine neutral surface charge and hydrophilicity, providing
significant reduction in fouling rates and increasing membrane efficiency by restoring nominal performance
after cleaning. LFC membranes are available in 4” and 8” diameters.

Combining the attributes of a neutral surface charge & hydrophilicity
• Enhanced membrane chemistry for increased
chemical resistance
• Innovative feed spacer design to minimize trapping of
small colloidal particles
• Proprietary vented seal carrier to eliminate pressure-shock
damage during system startup

LD represents a patented 34 mil thickness feed
spacer that represents low differential pressure
(ΔP), prevents colloidal fouling and increases
effectiveness of membrane cleaning.

LFC3-LD
• High permeate flow – 11,000 gpd (41.6 m3/d)
• High salt rejection – 99.7% (99.5% minimum)
• Increased membrane durability
• Lower dP (differential pressure)
• Greater tolerance to high pH cleanings
• Improved flux distribution
