Hydranautics ESNA1-LF2-LD Nanofiltration Membrane 8" x 40"

Nanofiltration membranes remove particles with a molecular weight cutoff of 200 to 1500. These membranes are ideal for applications requiring the removal of divalent ions, organics, color, bacteria and viruses. Each are ideally suited for integration with either RO or UF membrane products for primary or secondary treatment.

ESNA membranes by Hydranautics are designed using the latest technology and exhibit unparalleled performance at ultra-low pressures. Ideal for softening applications and removal of pesticides and pathogens, ESNA membranes provide 91%-99% salt rejection.

ESNA membranes also remove iron and TOC (Total Organic Carbon), while allowing passage of monovalent ions like sodium and chloride. This makes them the preferred choice for municipal potable water systems. Hydranautics advanced membrane technology and unique features of ESNA membranes help achieve significant savings in operation cost and energy. This makes them these membranes the preferred choice for municipal potable water systems.

ESNA1-LF2-LD is a high flow nanofiltration membrane that provides superior Natural Organic Matter (NOM) rejection and moderate hardness rejection, operating at less than 100 psi pressures. Thus, the membrane offers savings in costs and energy.
ESNA1-LF2-LD use patented Low Differential LDTM technology designed to minimize colloidal fouling.

ESNA1-LF2-LD membranes use a patented 34 mil thickness feed spacer that prevents colloidal fouling and increases effectiveness of membrane cleaning. As a result, the ESNA1-LF2-LD membrane does not need to be cleaned frequently ? thus reducing treatment cost ? while offering extreme durability and consistent performance.

ESNA1-LF2-LD membrane is acclaimed for its high NOM and color rejection. It also significantly reduces operating costs.
