Product Description

LFC3-LD from the LD Technology™ innovative low fouling membranes combines the attributes of a neutrally charged surface with hydrophilicity to achieve the lowest organic and colloidal fouling in the most demanding feed water conditions.
True hydrophilic membrane chemistry with LD Technology™

Combining the attributes of a neutral surface charge and hydrophilicity, LFC3-LD provides significant reduction in fouling rates increasing the membrane’s efficiency by restoring nominal performance after cleaning.

The low fouling composite LFC3-LD (Low Differential Pressure) provides a neutral surface charge that reduces fouling when treating wastewater and surface water with high fouling potential. With the low fouling LD Technology™, the differential pressure gets reduced lowering the biological and colloidal fouling inside the membrane, and successfully reducing the number of cleanings required.

Features and benefits:

• 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

Applications:

• Municipal wastewater treatment
• Industrial wastewater treatment
• Wastewater with organic fouling potential

Key features:

• 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
