Low Fouling Composite
LFC

PDF FORM featured product

LFC1 and LFC3

¬ Hydranautics' unique hydrophilic chemistry make these the only true low-fouling membrane in the industry for applications which demand high-efficiency flow and the highest salt rejection

LFC3 LD

¬ The Low Fouling Composite LFC3-LD (Low Differential pressure) provides a neutral surface charge that reduces fouling in wastewater and surface water with high fouling potential for reuse and reclaim applications.
