LFC3-LD - 1

True Hydrophilic Membrane Chemistry with LD Technology™ 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 Superior membrane technology is the key to Hydranautics’ innovative LFC (Low Fouling Composite) membranes. LFC3-LD membranes offer breakthrough technology in the treatment of difficult feedwaters and municipal wastewaters. Until now, these applications required significant pretreatment prior to being subjected to a composite polyamide membrane, which is eliminated with the use of the LFC3-LD membrane. 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! Applications: Municipal wastewater treatment Industrial wastewater treatment Wastewater with high biological and organic fouling potential Performance: Permeate Flow Salt Rejection Applications Data: pH Range, Continuous (Cleaning) Maximum Feed Flow * The limitations shown here are for general use. For specific projects, operating at more conservative values may ensure the best performance and longest life of the membrane. See Hydranautics Technical Bulletins for more detail on operation limits, cleaning pH, and cleaning temperatures. Test Conditions: The stated performance is initial (data taken after 30 minutes of operation), based on the following conditions 1500 PPM NaCl solution 225 psi (1.55 MPa) Applied Pressure 77oF (25o C) Operating Temperature 15% Permeate Recovery 6.5 - 7.0 pH Range Key benefits High permeate flow 3 11,000 gpd (41.6 m /d) High salt rejection 99.7% (99.5% minimum) Lower colloidal fouling Reduced biofouling Increased membrane durability Lower dP (differential pressure) Greater tolerance to high pH cleanings Improved flux distribution
