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-LF-LD are high-performance nanofiltration membranes ideal for softening applications and removal of pesticides, bacteria and viruses. They provide 50%-90% salt rejection with ultra-low-pressure operations, increased energy savings, and significantly lower installation and operating costs.

They use patented Low Differential LDTM technology designed to minimize colloidal fouling.

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

ESNA1-LF-LD membrane is globally acclaimed for high hardness rejection characteristics in softening applications. It significantly reduces operating costs and provides optimum hardness rejection in softening applications.
