Hydranautics ESNA1-LF2-LD


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.

ESNA1-LF2-LD membrane is available in 8-inch diameter sizes.
