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.

ESNA1-LF-LD membrane is available in 4-inch and 8-inch diameter sizes.
