Brackish Low-Fouling
LFC® (Low Fouling Composite) elements combine neutral surface charge and hydrophilicity, providing significant reduction in fouling rates and increasing membrane efficiency by restoring nominal performance after cleaning. This membrane is well suited for the treatment of difficult feed waters for numerous municipal and industrial applications, which up to now required significant feed water pretreatment upstream of any composite reverse osmosis membrane.
LFC-3-LD Membrane Elements with Hydranautics 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 Feedwater conditions. Hydranautics LFC3-LD membrane elements are designed with a thicker brine spacer lowering the Delta P meeting the increased demand for lower fouling membranes that require less frequent cleanings while maintaining a high permeate flow.

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.
