Membrane Formulations are designed to accommodate varying levels of seawater salinities worldwide with reliable field-proven performance. SWC5-LD-4040 membranes feature Hydranautics LD Technology - high-performance RO technology that helps reduce fouling from colloidal particles and biological growth. LD Technology uses proprietary feed spacers to reduce bio-growth (NSF 61 approved For drinking water). This innovative feed spacer design prevents trapping of small colloidal particles and improves the effectiveness of cleanings.
