Hydranautics ESNA elements provide 50% - 91% salt rejection with ultra-low operating pressures (below 100psi), and are ideal For softening applications and the removal of pesticides, bacteria, or viruses. Compared to conventional pretreatment, Hydranautics combine benefits of high recovery and low footprint requirement due to its optimized membrane area and novel cleaning regimes. 

Pricing is listed For membrane quantities up to 12. For pricing on quantities larger than 12 elements, please contact customerservice@evoqua. com to get a quote from a local salesperson.

ESNA1-LF-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 trapping of small colloidal particles and improves the effectiveness of cleanings.
