Enjoy up to 250% greater productivity per membrane area compared with conventional polyamide membranes, at the lowest cost per gallon produced. ESPA2-LD 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 the trapping of small colloidal particles and improves the effectiveness of cleanings.
